– Potential improvements in cancer therapy with fewer side effects
– Advanced drug delivery systems for better medical treatments
– Environmental benefits through reduced chemical waste and pollution
Background
The nanomaterial industry generates large quantities of metal-based nanomaterials for various technological and biomedical applications, but conventional synthesis methods place a burden on the environment through toxic chemicals and hazardous waste. Green synthetic approaches have emerged as eco-friendly, sustainable alternatives using nature-derived production methods to reduce the ecological footprint.
Objective
To provide a comprehensive review of recent green methodologies for synthesizing silver and gold nanoparticles, survey major nanoparticle characterization techniques, and examine the biological effects and biomedical potential of green synthesized silver and gold nanoparticles.
Results
Green synthesis methods successfully produced silver and gold nanoparticles with controlled size, shape and surface properties. The biological entities used in synthesis significantly influenced the physicochemical characteristics and biological activities of the nanoparticles. Plant-mediated synthesis showed advantages over microbial methods in terms of speed, scalability and ease of production. The nanoparticles demonstrated antimicrobial effects against various pathogens and selective cytotoxicity against cancer cells while showing biocompatibility with normal cells.
Conclusion
Green synthesized silver and gold nanoparticles show great potential for biomedical applications including antimicrobial therapy, cancer treatment, drug delivery, and biosensing. However, careful selection of biological materials and comprehensive characterization are essential to ensure reproducible synthesis and predictable biological performance. Further optimization and standardization are needed for industrial scale production.
