Description and Specifications

What is Silver Nanopowder?

Silver nanopowder (AgNPs) is a fine particle of silver, also known as silver nanoparticles. Its size varies from 1nm to 100 nm. The nanoparticles (Np) have a large percentage of silver oxide. Adding metal oxide, silicate, and polymers improves the bio-sensing of Silver NPs. Silver nanoparticles come in various shapes, such as spherical and diamond. It is commonly used in bio-sensing. It has high conductivity, powerful signal capacity, and biocompatibility. It is widely used in medicine, cosmetics, and many other industries. It is also used in environmental health, mechanics, and biomedical science. It is utilized in space industries and drug-gene delivery as well.

Silver NP is antimicrobial and effective against fungi, viruses, and algae. Its nature kills. It disrupts the cell membrane and stops the bacteria from growing again. The synthesis of AgNPs is entirely eco-friendly, cost-effective, and non-toxic. Metallic silver usually is not active. But when it contacts a reducing agent, it becomes active and is used in many fields.

When a silver nanoparticle is exposed to a specific light, the electromagnetic field sticks to electrons. This forms a charge separation, creating a dipole movement. This oscillation is maximum at a typical frequency. The shape of silver nanoparticles can be changed to control how it absorbs light. The smaller nanoparticles absorb light. The larger one’s exhibit scattering and move toward longer wavelengths. It has properties that help prevent bacteria growth. It is important in dental, surgical, wound, and burn treatments. Normally, silver-based compounds are highly toxic to microorganisms. Adding it to cells creates reactions that kill harmful bacteria.

Synthesis of Silver Nanoparticles

Silver NPs have various synthesis methods. The chemical method is preferred. Silver is broken down to nanosize colloidal silver in an aqueous liquid. The small silver particles is not stable. We need a stabilizing agent, Dodecanethiol, to make the reaction stable. It gets absorbed on the surface and forms a protective sheath. During the synthesizing of the AgNPs, drastic changes in shapes and sizes occur.

Features of Silver Nanoparticles

  • Small Size: The small size of this material allows it to mix seamlessly with other composites. This quality makes it ideal for medical applications.
  • Non-toxic: The green synthesis approach includes mixed-valence polyoxometalates, Tollens, and biological and eradication methods, making the nanoparticles non-toxic.
  • High surface area-to-volume ratio: A high surface area-to-volume ratio means there’s a huge surface area. This big surface area can hold lots of ligands, which are molecules binding to a central metal.
  • Absorption ability: The silver nanoparticles absorb well into the cell membrane. This causes changes and leads to the death of bacterial cells.
  • Electrical conductivity: Silver is high in electric charge conductivity.
  • Antimicrobial properties: Silver nanoparticles have antimicrobial properties because they release silver ions. This is considered a revolutionary way to kill microbes.

Application of Silver Nanopowder

The peptides colours and effects on silver nanopowder can be sensed. The peptides also impact the formation of silver nanoparticles. The efficiency of nanopowder-based sensors can be very high. It is widely used as a probe for surface-enhanced scattering and metal-enhanced fluorescence. It is also used similarly. It is also used as a sterilized nanomaterial in medical products. It is used in food, textile refrigerator surfaces, and personal care products. It is used with titanium dioxide to prevent coalescence in chemical reactions. Furthermore, it serves as the catalyst.

Safety Measures

  • Wear gloves, safety glasses, lab coats, and respirators when handling silver nanopowder.
  • Work in a well-ventilated area or use a fume hood to reduce exposure to airborne particles.
  • Minimize skin contact, and wash affected areas with soap and water if it occurs.
  • Do not eat, drink, or smoke in areas with nanopowder to avoid ingesting it.
  • Use methods to minimize dust and aerosol generation; consider enclosed systems.
  • Store it away from incompatible materials and label containers correctly.
  • Train personnel on hazards and emergency response when working with silver nanopowder.
  • Follow emergency procedures. Use eyewash stations and safety showers. Seek medical help after exposure.
  • Regularly assess risks and implement additional safety measures as needed.
  • Dispose of its waste following local regulations to prevent environmental contamination.
