Abstract

It was investigated that the cadmium sulphide nanoparticles causes lethal cellular toxicity on three different pathogenic fungal species namely Candida albicans, Candida parapsilosis and Candida trophicalis respectively. It was found that cadmium sulphide nanoparticles, whose size ranges between 35nm and 65nm were synthesized through wet chemical precipitation method. This was further characterized by XRay Diffraction analysis and Fourier Transformed Infra Red Spectroscopy. Different concentrations of cadmium sulphide nanoparticles, such a way, 250μg/ml 500μg/ml and 1mg/ml were taken and subjected to antimicrobial test, whose inhibitory zone varies for each candida species. Also, it was predicted that 1mg/ml nanoparticle concentration was responsible for significant fungicidal effects which produces a maximum zone of inhibition of 17mm diameter against Candia trophicalis.
