ABSTRACT

The application of bio-nanotechnology is one of the most vigorous researches in present science and technology. It has emerged up as integration between biotechnology and nanotechnology for developing biosynthetic and environmental friendly technology for synthesis of nanomaterials. Nowadays, copper based topical creams have been widely used as a UV-blockers. In this study the copper nano-particles are synthesized by using extract of Indian gooseberry’s (phyllanthus emblica). Reduction of copper nano-particles was confirmed by UV-VIS analysis. The chemical groups studied using FT-IR analysis, strong peak at 1046.43 which is the characteristics of C-N stretching vibrations. SEM and TEM analysis showed the shape and average size of nano-particles. Zebrafish (danio rerio) embryos were used to conform the UV- blocker property of the synthesized copper nanoparticles and showed the UV-blocker property. Based on the result obtained with further analysis, synthesized copper nano- particle can be utilized in various fields such as cosmetology, dermatology, nanotechnology and so on.
