The present study reports an eco-friendly approach to synthesize gold nanoparticles by simple reduction of chloroauric acid using Moringa oleifera leaf extract as reducing agent. Aqueous chloroauric acid when exposed to leaf extract was reduced and converted to gold nanoparticles in the size range between 20–60 nm at normal room temperature. Various phytochemicals present in the extract act as reducing agents and stabilizers. Gold nanoparticles were characterized by UV-Vis spectroscopy, atomic force microscopy and dynamic light scattering method. Leaf extract mediated gold nanoparticles exhibited excellent stability for more than thirty days at room temperature. This environment friendly approach of stabilized gold nanoparticle synthesis is non-toxic, cost-effective and can be efficiently utilized for several biomedical applications.

More about this publication?
  • Bionanoscience attempts to harness various functions of biological macromolecules and integrate them with engineering for technological applications. It is based on a bottom-up approach and encompasses structural biology, biomacromolecular engineering, material science, and engineering, extending the horizon of material science. The journal aims at publication of (i) Letters (ii) Reviews (3) Concepts (4) Rapid communications (5) Research papers (6) Book reviews (7) Conference announcements in the interface between chemistry, physics, biology, material science, and technology. The use of biological macromolecules as sensors, biomaterials, information storage devices, biomolecular arrays, molecular machines is significantly increasing. The traditional disciplines of chemistry, physics, and biology are overlapping and coalescing with nanoscale science and technology. Currently research in this area is scattered in different journals and this journal seeks to bring them under a single umbrella to ensure highest quality peer-reviewed research for rapid dissemination in areas that are in the forefront of science and technology which is witnessing phenomenal and accelerated growth.
