Abstract:

A novel technique of utilizing the dead banana flies (Drosophila Sp.) broth is reported with a conviction that dead animals and their tissue/organ wastes too can participate in nanoparticle synthesis. A very simple environment friendly protocol employing the broth of the fly yielded chalcognide (CdS) nanoparticles. X-ray and transmission electron microscopy analyses are performed to ascertain the formation of CdS nanoparticles. Individual nanoparticles as well as a few aggregate having the size of 5–18 nm are found. UV–Vis spectroscopy study revealed the surface plasmon resonance at 427 nm. The absorbance spectrum was used to estimate the value of optical band gap and particle size of CdS nanoparticles. The product also showed blue shift in the UV–Vis and PL spectra. A possible involved mechanism for the biosynthesis of CdS nanoparticles has also been proposed in which participation of Tropomyosin, Chitin and Metallothioneins is suggested.

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.
