“…Due to drawbacks such as the use of extreme conditions and hazardous reagents, the synthesis procedures have shifted towards eco-friendly approaches involving living entities, either using unicellular or multicellular organisms. Biological constituents, as depicted in Figure 1, serve to be a great platform for their non-toxic and economic synthesis [16], which not only include various microorganisms and plants but also their products and components such as extracts, isolates, enzymes, etc. These have been effectively utilised in polymer preparation, catalysis, sensor technology, disease management, and labelling of optoelectronic recorded media [13].…”

Advanced agronomic methods, urbanisation, and industrial expansion contaminate air, water and soil, globally. Agricultural and industrial activities threaten living biota, causing biodiversity loss and serious diseases. Strategies such as bioremediation and physiochemical remediation have not been effectively beneficial at treating pollutants. Metal-based nanoparticles (NPs) such as copper, zinc, silver, gold, etc., in various nanoformulations and nanocomposites are used more and more as they effectively resist the uptake of toxic compounds via plants by facilitating their immobilisation. According to studies, bio-based NP synthesis is a recent and agroecologically friendly approach for remediating environmental waste, which is effective against carcinogens, heavy metal contamination, treating marine water polluted with excessive concentrations of phosphorus, nitrogen and harmful algae, and hazardous dye- and pesticide-contaminated water. Biogenic resources such as bacteria, fungi, algae and plants are extensively used for the biosynthesis of NPs, particularly metallic NPs. Strategies involving green synthesis of NPs are nontoxic and could be employed for commercial scale production. Here, the focus is on the green synthesis of NPs for reduction of hazardous wastes to help with the clean-up process.
