“The production of quantum dots necessitates the use of very toxic precursors and solvents like TOP or TOPO, which have substantial upstream and downstream environmental consequences . There is a significant burden of organic and inorganic pollutants on air, water, and soil from the chemical production of cadmium selenide QDs. During the chemical production of CdSe, oxides of sulfur, nitrogen, and carbon are emitted into the air, while sulfur, sodium, iron, oils, and chloride ions are the primary water pollutants . As an example, conventional production utilizes the organometallic compound dimethyl cadmium as the cadmium precursor; however, dimethyl cadmium is an exceedingly poisonous, costly, and unstable solvent, making it unsuitable for large-scale synthesis . In comparison to conventional processes, microbial approaches include environmental benefits such as the capability to synthesize at room temperature and pressure, the utilization of renewable materials as electron donors, the utilization of inexpensive microbes, and the creation of biocompatible nanomaterials out of trash . The toxicity of an environment may therefore be decreased by the action of microbes.”
