Novel Approach for Silver Nanoparticle Synthesis Using Aspergillus terreus CZR-1: Mechanism Perspective
A novel biological approach for the rapid and cost effective synthesis of silver nanoparticles was attempted in the limelight of nanotechnology research. The present study demonstrates the synthesis of silver nanoparticle using fungus Aspergillus terreus CZR-1 (NCBI GenBank Accession
No. JF 681300). The fungal isolate was identified on the basis of morphological and molecular parameters. Transmission electron microscope (TEM) was used for size and shape study that reveal the spherical structure of monodispersed silver nanoparticle. To ensure the elemental proportion, electron
dispersive spectroscopy (EDS) was performed which confirms the 97 atom% of silver. The average size of silver nanoparticle was calculated using dynamic light scattering (DLS) was obtained to be 2.5 nanometer and the polydispersity index (PDI) was 0.195. The crystal structure of silver nanoparticle
was confirmed by high resolution transmission electron microscope (HR-TEM) and selective area electron diffraction (SAED) pattern.

- 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.
