Abstract
Nanobiotechnology is a rapidly developing sector that is influencing every field of study, from electronics to biology. The core of nanobioctechnology is nanoparticles, because of their incredibly tiny size and large surface area, nanoparticles are capable of bringing about treatments and cures for illnesses that were previously not achievable. In this study zinc sulfide nanoparticles were synthesized by using co-precipitation method, this method produced high yield of nanoparticles with in less time and inexpensive chemicals which was easily available. 0.005mol of zinc acetate and 0.01mol of sodium sulfide were used in this research. Initially clear color of solution was observed which was changed into black color. Centrifuged the solution for 30 minutes at 300 rpm and then dried it at 110 degrees Celsius for 24 hours. UV analysis was done and the maximum absorbance was observed at 500 nm. FTIR analysis also confirmed the synthesis of ZnS nanoparticles. Anticorrosive activity is performed on the iron bar with the aid of nanoparticles which gave the positive results. Agar well diffusion method and culture based method were carried out and significant antibacterial property of the synthesized ZnS nanoparticles was observed against gram negative bacteria E. coli.
