A review on environmentally benevolent synthesis of CdS nanoparticle and their applications

Abstract

The word ‘Nano’ received great attention of world, due to their fabulous and novel applications in numerous fields. Cadmium sulphide nanoparticles (CdS NPs) are unique in their properties due the size and shape, and are popular in the area of biosensor, bio-imaging, nano-medicine, molecular pathology, antimicrobial activities, photovoltaic cells, semiconductor, and drug delivery, etc. Due to its fascinating applications, it was synthesized using several methods and explored for its all possible applications. The most affordable, efficient, friendly and biocompatible way of creation of CdS NPs is biogenic synthesis using microorganisms such as bacteria, fungus, algae, enzymes, proteins and parts of plants. In biogenic synthesis of CdS, cadmium undergoes bio-reduction by the variety of natural products present in microorganism as well as in plants. In present review, inclusive study was piloted on the nano-synthesis, characterization and various applications of CdS NPs made using different plant sources and microorganism. • The CdS nanoparticles have been effectively produced by green synthesis using biological substrates. • The effort is made to categorize variety of biomaterials such as plants and microbes under green synthesis approach. • The study made here brings forward minute details of types of green protocols, bio-materials used, particle size, morphology, and multifunctional applications carried out of CdS nanoparticles. • The current review highlights on the diverse approaches of bio-inspired synthesis of CdS nanoparticles and their potential use towards biomedical, energy, and environmental applications.
