What is the difference between antibacterial nanosilver and nanocopper

Nano silver antimicrobial agent: It is a metal silver element with a particle size of nano, and the particle size is mostly about 25 nanometers.

Then, using a special technology, nanosilver is put into a carrier to make a solution.

Nano-silver ions.

Antimicrobial agents: nanomaterials due to small particle size, specific surface area.

Large, high surface energy, and large proportion of surface atoms, therefore, it exhibits three major effects: surface effect, small size effect, and macroscopic quantum tunneling effect.

Differences: Generally there will be descriptions in the product, if there are other ingredients, such as: complex silver, complexed silver, nano silver ions.

However, if it is not clearly stated that it is nano-silver particles, it belongs to silver ion antibacterial agents.

The production threshold of silver ions is very low, and the process is simple.

The diameter of silver nanoparticles is generally 5-10 nm; Whereas, the diameter of silver ions is measured in angstroms (a smaller unit of atomic measurement.

At present, the original color of nanosilver in the spectral test is light yellow or light red, and it cannot be colorless.

Therefore, if the color of the solution is colorless, then it can be basically judged to be a silver ion solution.

Nanosilver and nanocopper have a strong antimicrobial effect. The physical properties and applications of the two are different. Silver nanoparticles are often used as efficient, long-lasting, and non-toxic antimicrobial agents, while copper nanoparticles have low sterilization efficiency and are not durable, but their ductility has been widely used.

At present, safe and efficient nanosilver is mainly used for antibacterial.

Silver nanoparticles are safe, and at very low concentrations, silver nanoparticles exhibit strong antibacterial properties against microorganisms. Whereas, toxicity to mammals is low, and complications are rare. Secondly, the durability is good, and nano-silver can be attached to carriers such as chitosan to continuously release zero-valent silver ions.

Maintain a more stable silver concentration to achieve the purpose of long-lasting antibacterial. Third, broad-spectrum antibacterial, nanosilver can effectively inhibit more than 650 kinds of pathogenic bacteria including Brewing Bacillus aureus, Staphylococcus, Escherichia coli, Pseudomonas aeruginosa and other pathogenic bacteria, as well as fungi such as Ringworm. Fourth, it is not easy to develop drug resistance, and bacteria treated with nano-silver basically cannot survive, which can prevent bacteria from developing drug resistance.

Fifth, nano silver also has the advantages of small toxicity and easy use.

Nano-copper is a product made of nano-materials, which is superplastic and malleable, and can be elongated more than 50 times at room temperature without cracking.

Nano-copper can be used as a wave-absorbing material.

It has the advantages of frequency bandwidth, good compatibility, small quality and thin thickness.

In addition, nano-copper reacts with oxygen more easily than ordinary copper.

Due to its unique optical, electrical, magnetic, thermal and chemical properties, nano-copper powder can be widely used in high-efficiency catalysts and conductive plasma.

Ceramic material, high conductivity, high ratio.

It can be used as an additive in the textile industry and develop antibacterial fibers while having a broad-spectrum antibacterial effect and without the shortcomings of drug resistance of general antimicrobial drugs.

Expansion: 1. A nanometer is a unit of length.

1 nanometer is equal to 1 10-9 meters, and the particles of the substance have special properties when they reach the nanoscale.

Copper nanoparticles are finer and chemically reactive.

When the contact surface is large, so the reaction rate.

Fast. When elemental copper is made into "nano copper", it has a very strong chemical activity and can be burned in the air.

2. The mechanical properties of copper nanocrystals with an average volume of only 80 nanometers are amazing, and the strength is not only 3 times higher than that of ordinary copper, but also the deformation is very uniform, and there is no obvious regional narrowing.

This mechanical property of copper nanocrystals opens up a bright prospect for the fabrication of elastic substances that split equilibrium at room temperature.

Metallic and non-metallic surface conductive coating treatment Nano copper powder has a highly activated surface and can be used under oxygen-free conditions.

The coating is applied at a temperature below the melting point of the powder. It is used in the production of microelectronic devices.

High-efficiency catalyst Copper and its alloy nano powders are used as catalysts with high efficiency and selectivity, and can be used for dioxide.

Carbon and hydrogen are combined into methanol and other catalysts in the reaction process.

Conductive paste: Replacing the powder with nano copper can greatly reduce the cost of preparing electronic paste with superior performance. Promote the further optimization of microelectronic processes.

Anti-corrosion and deodorization The strong bactericidal effect of nano-copper can kill microorganisms and achieve a good anti-corrosion and deodorization effect.

Thermal conductivity and anti-wear Nano copper directly acts on the metal surface of the machine, which plays a role in repairing the surface of metal wear.

After the heat is emitted by friction, the product can use its nano properties to adhere to the metal surface, so that the original rough surface of the metal becomes smooth, and the protective film formed on the metal surface is stronger and smoother, so as to prolong the metal service life of the parts and save energy.

Nano-sensitive copper can be used in hot hydrogen generators, gel propellants, self-laughing nabburn active agents, catalyst bumper ears, water hand washing adsorbents, workpiece active agents, etc. Nanocopper reacts with oxygen more easily than ordinary copper.

It is mainly oil-soluble nano-copper, which does not carbonize at high temperatures like other organic substances, and can also fill friction defects at any time, which really plays a self-healing role.

Because nanosilver is not charged, it will not bind to a variety of bioactive substances in living organisms, so it will not be toxic and bacteria will not develop drug resistance.

Silver ions, we can be regarded as an antibacterial material or substance, the antibacterial effect of the material, generally speaking, is in a certain material on the vitality of microorganisms to produce adverse effects and consequences, these adverse effects and consequences, the most concentrated manifestation is to affect the growth of microorganisms, reproduction and death.

Silver ions are positively charged "cations".

It can produce redox reaction with the active tissues of living organisms, thereby losing activity and causing damage to organisms (traditionally called toxicity).
