I am Dr. Ratan Sarkar, an Associate Professor in the Department of Physics at Jogesh Chandra Chaudhuri College, University of Calcutta. My research spans nanoscience, biomolecular interfaces, magnetic nanomaterials, graphene-based hybrids, supercapacitors and photocatalytic and biomedical applications. I completed my B.Sc. (Hons.) and M.Sc. in Physics from Visva-Bharati University, followed by a Ph.D. in Physics from Indian Association for the Cultivation of Science (IACS).
My Ph.D. research focused on bio-templated nanoparticle formation, exploring how biomolecules such as lipids and proteins can guide the nucleation, growth, and assembly of inorganic nanoparticles. Using Langmuir and Langmuir–Blodgett techniques, I studied nanoparticle–protein interactions, lipid monolayers, and the interfacial behaviour of biomolecules. This work contributed to understanding bio-inspired pathways for synthesizing functional nanomaterials.
My subsequent research expanded into magnetic nanoparticles, ferrite nanostructures, and graphene oxide composites. I have worked on photocatalysis, drug delivery and supercapacitors. These studies combine nanostructure design, magnetic behaviour, optical properties, and biocompatibility, highlighting applications in environmental remediation and targeted drug delivery.
I have published in journals such as Material Research Bulletin, Flat Chem, The Journal of Physical Chemistry B, RSC Advances, Journal of Microencapsulation, Journal of Magnetism and Magnetic Materials, Colloids and Surfaces B, and Indian Journal of Physics etc. I have also authored a book chapter published by Elsevier.
I have presented my research at numerous national and international conferences, including ICN+, ICONSAT, JEMS (Germany), and ICOMF14 (France), and have delivered invited lectures on nanoparticle synthesis and self-assembly. I received UGC International Travel Support (2018), DST Travel Grant (2012), and qualified the Joint CSIR-UGC NET.
My core research interests include:
• Bio-templated nanomaterial synthesis
• Graphene oxide and hybrid nanocomposites
• Magnetic and ferrite nanostructures
• Photocatalysis and dye degradation
• Nanomedicine and drug delivery
• Nano materials for supercapacitor application
Through my academic and research activities, I aim to advance sustainable materials, bio-inspired synthesis routes, and multifunctional nanostructures with applications in healthcare, environment, and advanced technologies.
