A comprehensive review on biogenic metallic, metal oxide and metal sulfide nanoparticles for water treatment and sensing applications

Abstract

Green nanotechnology has recently emerged as a fast-advancing and interdisciplinary topic of study. Adopting green synthesis is critical for ensuring environmental sustainability and promoting health and safety. This article offers a comprehensive examination of several manufacturing techniques used for biogenic materials. This study focusses on the use of microorganisms and plant extracts to develop biogenically synthesised materials, including metals, metal oxides, metal sulphides, and their composites. This strategy is seen as a more ecologically sustainable substitute for conventional chemical methods. This article presents a conclusion on the green synthesis of nanostructured materials and their many uses, such as the adsorption and degradation of pollutants. This paper also provides a concise overview of colorimetric, electrochemical, and fluorescence sensing methods used to assess water quality. A decade-long investigation has been carried out to thoroughly examine biogenic materials for diverse applications. Moreover, it also presents current advancements in biogenically synthesised materials. Finally, this study provides a critical analysis of the possible uses and future prospects of biogenically synthesised materials, as well as the need for more research in this field.
