Antibacterial effect of calcium oxide nano-plates fabricated from shrimp shells

Abstract

We used shrimp shells as a novel and green source of precursors to produce calcium oxide nano-plates ranging from 40 to 130 nm (in length) and 30 to 100 nm (in width). These nanoparticles were found to possess effective antimicrobial activity against gram positive and gram-negative bacteria. The percentage yield of the calcium oxide nano-plates (8%) enables this method to become a highly effective industrial technique.
