Journal Title:Journal of Chemical, Biological and physical sciences

Nanomaterials have a great many medical applications which are growing rapidly to lead the wide scale production and application of engineered nanoparticles. Extension of nano engineering to the formation of fibers, sheets and volume-filling materials such as gels, networks and scaffolds as well as other none medical products such as cosmetics, sunscreens and food products are increasing. However, extensive usage of them may cause unwanted damages and toxicity to the living cells due to the increased surface reactivity of nanoparticles. The properties of many conventional materials will be changed when they are in nanoparticle form. This is typically because nanoparticles have a greater surface area per weight than larger particles which make them to be more reactive to some other molecules. In recent years ZnO nanoparticles have been used in different industrial sectors such as medicine, cosmetic materials and concrete, anti bacterial, textile and automotive industries. ZnO is currently being investigated as an antibacterial agent in both microscale and nanoscale formulations. Results have indicated that ZnO nanoparticles show antibacterial activity apparently greater than microparticles.
