Biophysics and Beyond

Green nanotechnology has emerged as a sustainable and eco-friendly alternative to conventional nanoparticle synthesis methods, minimizing the use of toxic chemicals and harsh reaction conditions. In this approach, biological resources such as plant extracts play a key role in the reduction and stabilization of metal ions to form nanoparticles. Among various nanomaterials, magnetite (Fe₃O₄) nanoparticles are of particular interest due to their excellent magnetic properties, chemical stability and wide-ranging applications in environmental remediation, catalysis and biomedical sciences. Plant-based synthesis is especially attractive because phytochemicals such as phenols, flavonoids, alkaloids and antioxidants act as natural reducing and capping agents, enabling efficient nanoparticle formation under mild conditions. Consequently, plant-mediated synthesis offers a cost-effective and sustainable pathway for producing Fe₃O₄ nanoparticles with significant potential for advanced environmental and technological applications.
