Abstract
Bio-inspired Nanotechnology and bio-inspired material fabrication is an emerging field of research in recent times and it comprises a new field called Bionanotechnology. It not only offers biosynthesis of material or biocompatible biomaterials but it offers a sustainable materials. In this article, it is reported for the first time that hemoglobin (Hb) protein mediated biosynthesis of calcium carbonate (CaCO3) nanoparticle preparation by Langmuir Blodgett (LB) technique. LB technique offers a surface chemistry method for biosynthesis of nanomaterials. The pressure-area isotherm data shows a stable pure Hb and Hb-CaCO3 composite Langmuir film which has been successfully transferred to the solid substrate. The LB film of Hb-CaCO3 composite has been characterized by TEM image, SAED pattern, high resolution fringe pattern of the calcium carbonate crystal. The demonstrated work finds huge potential in the field of Biomaterials and Bionanotechnology.
