摘要

The conventional methodologies involving chemical and physical modes of synthesizing nanoparticles are leaving behind hazardous footprints in the environment and have made the scientific community shift towards novel, sustainable approaches to manufacturing nanoparticles using bioresources like plants, fungi, bacteria, and algae. Nanoscale structures, possessing special plasmon resonance, can open up enormous avenues in all fields, especially in the field of agriculture. Among them, microalgae are gaining huge attention because of their special features like fast growth, tolerance to heavy abiotic stress, promising biomass productivity, and high multiplication rates even in nutrient-deficit water bodies and minimum cultivation time. Although there are sufficient reports of plant-based nanoparticle synthesis using green technologies, microalgae-mediated nanoparticles, and their vast applications, exclusively in the agricultural fields, are still found to be in their infancy. Thus, the present review precisely aims to compile the information regarding the synthesis of metallic nanoparticles using microalgae and their agricultural applications were discussed. Moreover, an attempt was made to expand present considerations of basic nanotechnology to the new horizons of applications in agriculture.
