Author(s): Ankur Malik and Jainendra Pathak
Abstract: Nanotechnology has revolutionized several scientific disciplines with its ability to engineer and modify materials at the nanoscale. Due to its environmental friendliness and prospective uses across many industries, green nanoparticle synthesis has attracted much attention. Green nanoparticle synthesis produces nanoparticles by using natural resources instead of toxic chemicals and energy-intensive processes, such as plants, microorganisms, and biomolecules. Recent trends include utilizing microbes, biomolecules including enzymes and proteins, and plant extracts as reducing and stabilizing agents. This process gives nanoparticles unique features that increase their potential applications across medicine, catalysis, and agriculture. The key pathways for synthesizing nanoparticles are physical and chemical, usually expensive and possibly hazardous to the environment. In the recent past, the evaluation of green chemistry or biological techniques for synthesizing metal nanoparticles from plant extracts has drawn the attention of many researchers. Algal/cyanobacterial secondary metabolites have emerged as one of the the most promising natural compounds in the field of biotechnology and biomedical research. Formation of nano-conjugates from such compounds is still an unexplored and interesting field of research.
