Biofabrication of Gold Quantum Dots Using Cascabela thevetia Through Microwave Irradiation
Abstract:Microwave assisted bio-based green synthesis of highly monodispersed spherical Gold Quantum Dots (Au-QD) using the Cascabela thevetia flower extract is reported. The method is simple, cost effective and easily reproducible. The most interesting thing about the Cascabela thevetia extract was that, it reduced the precursor HAuCl4 to Au0 only in presence of microwave irradiation, and could not be executed properly under thermal and/or mechanical conditions. The synthesised material exhibited the surface plasmon resonance at 520 nm. The transmission electron micrographs of the nanoparticles showed the formation of spherical nanoparticles. The material synthesised was characterised by HRTEM, Electron Diffraction and XRD. The biomaterial functioned both as reducing and stabilizing agent.

- 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.
