SILVER NANO PARTICLES-INDUCED CYTOTOXICITY

The demand for silver nanoparticles (AgNPs) is growing rapidly in many streams such as medical, pharmaceutical, healthcare, food, consumer, cosmetic, etc. Due to its use, it is used for several applications such as antibacterial properties, household, medicine. equipment and food industry, wound dressings, in diagnostics, orthopedics and anti-cancer agent. It has been found that these nanoparticles are unique in nature and are also able to change their “physical, chemical and biological properties and therefore can be used for various purposes. The preparation methods for the preparation of AgNPs are physical, chemical and biological. . Among all the three methods, the biological method is found to be a simple, eco-friendly, commercial and one-step method and does not require elevated temperature, pressure, force and lethal chemicals. Before applying nanoparticles for any purpose such as medicine, human welfare or healthcare, it is very important to characterize the prepared nanoparticles to verify the safety of any of the prepared nanoparticles. Analytical techniques that are used for the analysis of these AgNPs are UV-Vis spectroscopy, XRD, FTIR, DLS, XPS, SEM, TEM, AFM, etc. AgNPs have applications such as anticancer, antifungal, antibacterial, anticancer.
