Metal Nano Powder

Silver Nanoparticle has been used as an antimicrobial agent for centuries. For example, the Phoenicians used silver vessels to preserve water and wine during their long voyages. In addition, ancient Egyptians believed that silver powder provided beneficial healing and antidisease properties thus silver compounds were used for prohibiting wound infection prior to antibiotics. used silver sulfadiazine cream is the standard antibacterial treatment for serious burn wounds and is still widely used in burn units today. In addition to their potential electronic and transparent conductor applications, the emergence of nanosilver materials in antimicrobial consumer goods and medical products is driving the growth of the nanosilver.

Silver Nanoparticle the metallic nanoparticles, including gold, silver, iron, zinc and metal oxide nanoparticles, have shown great promise in terms of biomedical applications, not only due to their large surface area to volume ratio but also because they exhibit different biomedical activities. These have been demonstrated in experiments using gold and cerium oxide nanoparticles for the treatment of tumors and for anti-inflammation, respectively.For silver, this precious metal was originally used as an effective antimicrobial agent and as a disinfectant, as it was relatively free of adverse effects. However, with the development of modern antibiotics for the treatment of infectious diseases, the use of silver agents in the clinical setting had been restricted mainly to topical silver sulfadiazine cream in the treatment of burnwounds.

Silver Nanoparticle can be synthesized in a variety of different ways, each with its own advantages and disadvantages. Till now, the most common methods of Silver Nanoparticle synthesis are through chemical reduction of silver salt (e.g., AgNO3) using a reducing agent (e.g., sodium borohydride). During chemical reduction, silver ion (Ag+) receives an electron from the reducing agent and reverts to its metallic form (Ag0) eventually clustering to form Silver Nanoparticle. Silver Nanoparticles is the most often used silver salt for these chemical methods of Silver Nanoparticles synthesis due to its low cost and high stability. Generally, a capping agent [e.g, poly(N-vinyl-2pyrrolidone) (PVP)] is used during chemical reduction to stabilize the nanoparticles and prevent them from aggregating.

Silver Nanoparticle the availability of silver nanoparticles has ensured a rapid adoption in medical practice. Their application can be broadly divided into diagnostic and therapeutic uses.Early diagnosis to any disease condition is vital to ensure that early treatment is started and perhaps resulting in a better chance of cure. This is particularly true for cancer. Lin et al reported silver nanoparticle based Surface-enhanced Raman spectroscopy (SERS) in non-invasive cancer detection . This approach is highly promising and may prove to be an indispensable tool for the future. In terms of therapeutics, one of the most well documented and commonly used application of silver nanoparticles is in wound healing. Compared with other silver compounds, many studies have demonstrated the superior efficacy of Ag NPs in healing time, as well as achieving better cosmetic after healing.
