    The Preparation and Application of Nanoparticles

    What are nanoparticles, and how are they used? Nanoparticles The use of ceramic coatings in solar cells, scratch-resistant eyeglasses (and other products), anti-graffiti paints on walls, transparent sunglasses, stain-repellent fabric, self-cleaning glass, and crack-resistant paints is increasing.

    What are the components of a nanoparticle?
    Nanoparticles or ultrafine particles are defined as particles of matter with a size between 1 and 10 nanometres. The term can be applied to larger particles (up to 500 nm) or fibers or tubes with a diameter less than 100nm in just two directions.

    What is the effect of nanoparticles in the body on health?
    The effects of inhaled Nanoparticles Inflammation of the lungs and heart problems are possible. Human studies show that breathing soot triggers a generalized inflammatory response, and changes the system which regulates involuntary cardiovascular functions such as heart rate control.

    What are some examples nanoparticles of?
    Moreover, nanoparticles may be classified as either hard (e.g. titania, silica, or silicon dioxide particles) or soft (e.g. liposomes vesicles and nanodroplets).
    Some of the most common food products containing nanotechnology are candies (M&M's and Skittles), plastic containers, and baby bottles.

    Nanomaterials also have many applications in medicine and bioengineering.Targeting drugs with nanometer magnetic materials as drug carriers have been successfully developed, which are called "biological missiles".In other words, drugs are carried on the protein surface coated by magnetic Fe3O4 nanoparticles, injected into human blood vessels, and delivered to the lesion site through magnetic navigation to release drugs, which can reduce the side effects caused by drugs in the liver, spleen, kidney, etc.The information of various biochemical reactions and electrochemical information can be obtained by using nanosensors.Nanoparticles can be used as a nano robot, into the person's blood, to human body health checks, dredge in cerebral thrombosis, remove fat deposits in the heart arteries, viruses, and even can eat kill cancer cells, etc., can be predicted that with the development of the preparation of nanometer materials technology development and function, there will be more and more new nano material has been widely used in many high-tech fields.

    The growth of gold nanoparticles within tumors can help fight cancer
    In many studies, gold has shown to be a promising tool in the fight against Cancer. Researchers have developed a method to grow gold nanoparticles within cancer cells. They can aid in imaging, and they can even be heated to kill tumors.

    Previous research has used gold nanostars to battle cancer. However, one of the major challenges is getting these nanoparticles inside the tumors. They can be equipped with peptides which hunt down the cancer or they can sneak into tumors by attaching themselves to white cells.
    Researchers found that they could grow gold inside cancer cells. This method is quicker and doesn't need as much gold.

    The team used PEG as a vehicle for ionic Gold, which is basically gold salts dispersed in a liquid. The cancerous cellular environment converts the ionic gold into plasmonic gold particles when it is applied. The team claims that this can be done in just 30 minutes. It is much faster than traditional treatments which take up to 24 or more hours.

    The difference between nanoparticles and nanomaterials

    What is nanopowder? Nanopowder It is also known as nanoparticle and refers to ultrafine particle sizes between 1-100nm. Some people refer to it as ultrafine particle. It is bigger than atomic particles and smaller than normal particles. Nanoparticles are absorbed into the body by the outermost layer, such as the skin or the lungs. The amount of migration they undergo from the exterior to the internal depends on their physical and chemcial properties.
    What's the difference between nanomaterials (also called nanoparticles) and nanomaterials?
    Nanomaterials Refers to materials that are in the nanoscale (1nm100nm), in at most one dimension, in three-dimensional space. They can also be composed of these basic units. The particle diameter of 10 nanometers contains 4000 molecules and the surface-atoms are 40%. For example, a particle with a diameter of 1 nanometer contains 30 molecules and surface-atoms are 99%.

    Nano Cobalt Powder
    Nano cobalt is a powder that can be gray, black or spherical. Cobalt Nanoparticles can be used for a variety applications, such as sensors and imaging. Cobalt is classified as a hazardous substance and can cause skin allergies. Inhalation has been shown to cause breathing difficulties and asthma symptoms.
    Laser evaporation creates spherical metal particles. Cobalt does not have a high abundance, but it is widely distributed in soil, rocks, mineral water and oceans, meteorites, sunlight, star atmosphere and plants.

    How Can Gold Nanoparticles Be Used to Kill Bacteria

    One team discovered that bacteria can be exposed to nanoparticles of gold, which causes their cells to burst and leak material, leading to death.


    Each year, more than 25,000 people die from bacterial infection that cannot be treated with antibiotics. Drug resistance is increasing. Researchers are looking for other ways to combat the bacterial threat.
    Since ancient Egyptian times gold has been used for many medical purposes. Recently, doctors have started to use gold to treat and diagnose cancer. It is an inert metallic that doesn't react or change to contact with living organisms. It can be used in nanomedicine to make cancer cells grow.

    New research has revealed a mechanism whereby gold nanoparticles kill bacteria.
    The researchers made nanoparticles the size of stars and near perfect spheres in the lab. Each was approximately 100 nanometers across, which is one eighth of the width of a human hair.
    "What we found was the bacteria surrounding these nanoparticles began forming, then deflated and finally died like an inflatable. Vladimir Baulin of University of Rovira Wilhelli Chemical engineering department said, "It seems that the cell wall explosion."

    This theory was tested by researchers who built bacteria models and observed the interactions of these bacteria with tiny gold particles measuring just 100 nanometers.
    The results showed that the uniformity in the surface layers of these nanoparticles creates a mechanical force which stretches the cells of surrounding bacteria. This causes the bacteria to burst much like a balloon that is stretched from different points.

    The study was performed by The Universitat Rovira I Virgili (Spanish), the University of Grenoble (France), and the Universitat der Saarlandes (German), RMIT University, Australia. The article was published in Advance Materials.

    The gold nanoparticles, which are tiny particles made of gold, have a diameter between 1 and 100nm. They are highly electron dense, have dielectric properties and catalytic activity. They can bind with many biological macromolecules and not affect their biological activity.
    Two types of gold nanoparticles are available: solid powder and liquid solution.
    Solution of gold nanoparticles are sols that have been dispersed into an aqueous solution. The color of the nanoparticles depends on a variety of factors. Its color is determined by a number of factors. Smaller gold nanoparticles (2-5nm diameter) appear yellow. Medium-sized gold nanoparticles (10-20nm diameter) appear wine-red. Larger, more concentrated gold nanoparticles (30-40nm diameter) appear purplish. Additionally, it exhibits the characteristics of nanoparticles: quantum size effect; surface effect; volume effect; and macroscopic quant tunneling effect.

    Nano diamond has been widely studied in biological, electronic and quantum engineering fields

    Overview of Nano diamond The nano-diamonds, also known as diamond nanoparticles, are diamonds smaller than 1 micron in diameter and can be created by an explosive or meteorite strike. Due to its low cost, ease of large-scale synthetic, surface functionalization, high biocompatibility and easy synthesis, nano diamond has been extensively studied in the electronic, biological and quantum engineering areas.
    Structure of nanodiamond
    It is important to consider three main aspects of the structure and function of diamond nanoparticles. Through a variety of diffraction experiments, it was determined that the shape and size of diamond nanoparticles are spherical or rectangular. The diamond cage is the core of diamond nanoparticles. It is mostly made of carbon. Although the core structure is very similar to the diamond, the diamond nanoparticles have a surface similar to graphite. A recent study revealed that the surface is mainly made of carbon. However, it also contains a lot of phenol and pyrrole as well as sulfonic, carboxylic, and hydroxyl groups. Sometimes, there are defects in the structure of diamond-nanoparticles. A recent study has shown that the frequency and size of nitrogen-vacancy center decreases with diamond nanoparticles.
    Production methods for nano-diamond
    Other than the explosion, other synthesis methods include hydrothermal, ion bombardment and laser bombardment, microwave crystal chemical vapor deposition (MPCVD), ultrasonic synthesizing, and electrochemical. High-purity nanoparticles can also be produced by high-pressure and high-temperature graphite C3N4 decomposition. For commercial production of Nano Diamonds, the industry standard is detonation-synthesis. The most common explosive used to produce them is a mixture trinitrotoluene/hexose or monosaccharide.
    The explosion takes place in a stainless steel chamber that is sealed and oxygen-free. It produces Nano diamonds as well as other graphite compound averaging 5 nanometers. Nano diamonds can only be created by detonation synthesis if there is no oxygen. This happens at temperatures above 3000K and pressures over 15 GPa. To prevent the formation nanoparticles of diamond, the oxidation system must be rapidly cooled to increase the production of Nano-diamonds. This is because diamond remains the most stable under such conditions. Detonation synthesizers use liquid and gas coolants like water, water-based mousse and ice. Detonation results in synthesis, which is a mixture nano diamond particles and graphite carbon forms. Therefore, thorough cleaning must be done to remove all impurities. To remove metal and SP2 impurities, either solution phase nitric acids oxidation or gaseous Ozone treatment are used.
    Application prospect of Nano diamond
    Nano diamond's strength, hardness, thermal conductivity and biocompatibility are unique, making it a popular choice for precision polishing, lubrication and high-performance metal matrix composites.
    Nano diamond is a material of rich characteristics and connotations. This is an area that presents great opportunities and challenges. Nano diamond is a product of years of research and production. This material can be used to produce raw materials, defense industry, precision polishing industry, biomedicine, electronic, mechanical and chemical industries. There are many applications for this material in our everyday lives. I believe it will have a wide application in other industries in the near future.

    What are gold nanoparticles used for?

    What exactly is colloidal or sol gold? It is a colloidal suspension (or colloidal solution) of nanoparticles of gold in fluid (usually water). Colloid colors are typically wine red for spherical particle sizes less than 100nm or blue/purple (for more spherical particles, or nanorods).

    Property of Colloidal Gold
    Colloid gold nanoparticles' properties and applications are greatly affected by their shape and size. A rod-shaped particle, for instance, has transverse and longitudinal absorption peaks. Their anisotropy will impact their ability to self-assemble.

    How are gold nanoparticles utilized?
    Drug delivery system
    The biological distribution of drugs can be optimized to target diseased cells, tissues and organs with gold nanoparticles. If drug distribution is not sufficient, nanoparticles are able to deliver drugs. This includes targeting unstabil drugs like proteins, siRNA, and DNA. It also allows for drug delivery to more difficult locations (brain, retina and tumors). Their size and function determine the properties of nanoparticles. The properties of nanoparticles can also vary depending on their surface function and size. This is due to the variability in drug release or particle disintegration (e.g., sensitive biodegradable plastics that react to pH). An optimal nano-drug distribution system will ensure that active drug is accessible within the appropriate time and duration at the site of action. The concentration must be more than min. The effective concentration (MEC), should be lower than the min. toxic concentration (MTC).
    For drugs like Paclitaxel, nanoparticles of gold are being investigated. Hydrophobic drugs can only be delivered by molecular packaging. The nanoparticles were found to have a high efficiency in bypassing the reticuloendothelial systems.

    Enhancer for Radiotherapy
    It has received a great deal of interest to use gold nanoparticles and others containing heavy elements to raise the dosage to cancer patients. Due to the fact that gold nanoparticles can absorb tumors more than those in healthy tissues nearby, it is possible to increase the dose. Local deposition of radiation near nanoparticles seems to account for the biological effects of the treatment. It is similar to heavy ion therapy.

    Toxic gases
    Researchers developed an inexpensive and easy method of detecting hydrogen sulfide in the atmosphere based upon the anti-aggregation properties of gold nanoparticles. Hydrogen sulfide is dissected in an alkaline buffer solution. The solution creates HS,HS- which stabilises AuNPs. It also ensures they stay red. This permits visual assessment of hydrogen sulfide levels.

    What do gold nanoparticles consist of?
    Turkevich, et al.1951 devised a procedure for the production of AuNPs. This involved treating tetrachloroauric acids (HAuCl4) by boiling water with citric Acid. Citric acid is a reducer and stabilizer. Frances modified the ratio of citric acid to gold to improve the process. It has been used extensively to produce moderately stable, spherical AuNPs. However, it is also capable of producing larger AuNPs (e.g. 100 nm).

    Why is gold nanoparticles so red?
    The visible spectrum is where gold nanoparticles have their resonance frequency. Because smaller gold nanoparticles are more sensitive to violet, blue, green, and yellow wavelengths they appear red.

    What is Nano Silver Good For?

    Why is nano-silver good for you? The benefits of using nano-silver in various industries such as pharmaceuticals, healthcare, and consumer goods.
    These nanoparticles can be very tiny particles, with sizes from 1 to 100 nanometers. Nanosilver is composed of Silver nanoparticles. These nanoparticles are useful as antibacterial or antifungal agents in the industry, water treatment, consumer goods, as well as for cleaning clothing, cosmetics and food containers. In some filter systems to purify groundwater, silver nanoparticles can also be used.

    What does silver colloid consist of?
    Coloidal silver and silver solution both contain silver nanoparticles that are suspended in liquid bases.

    Are you allowed to eat colloidal Silver?
    When taken orally, silver accumulates in the body. The silver can build up in your body for many months, causing your skin, eyes and internal organs to turn bluish. It's called "argyria" by doctors. It is permanent.
    Only in very rare circumstances, colloidal silver may cause seizures or other serious side effects.
    It is possible for colloidal silver to interact with certain prescription drugs such as penicillamine, Depen, Quinolone Antibiotics and tetracycline.

    Colloidal Silver can be good for you health.
    The ability to kill bacteria through the destruction of proteins makes colloidal silver useful for wound dressings. However, silver is neither a useful mineral nor has any known functions in the body. The skin can turn permanently blue if it is taken orally. Brain function issues can also be caused by oral silver.
    While colloidal silver has been proven effective in treating infections, hay fever and skin conditions among other ailments, it is not supported by any scientific research. It is currently not possible to prove the effectiveness of colloidal sodium in treating COVID-19. The use of colloidal silver in the treatment of COVID-19 is not recommended.
    The scientific evidence is not in support of the treatment with colloidal Silver dietary supplements for any type of disease.
