Abstract:

A green, low-cost and reproducible Lactobacillus mediated biosynthesis of carbon coated Al2 O3 nanoparticles (cc-Al2 O3 NPs) is reported. The synthesis is performed near to room temperature in the laboratory ambience. X-ray and transmission electron microscopy analyses are performed to ascertain the formation of cc-Al2 O3 NPs. Individual nanoparticles of spherical shape having the dimensions of 8–22 nm are found. The probable mechanism involved for the biosynthesis of cc-Al2 O3 NPs has been discussed. An experiment for assaying the purification promise of cc-Al2 O3 NPs was also carried out in which appreciable lowering in the levels of pH, TSS and TDS was observed in water samples collected from two different sources.

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.
