Prof. Dr. M. R. Rajan | Nanoparticles | Excellence in Research Award

The Gandhigram Rural Institute- Deemed to be University | India

Prof. Dr. M. R. Rajan is a distinguished researcher whose work spans aquaculture toxicology, green nanotechnology, environmental biotechnology, and fish health management. His research primarily explores the synthesis, characterization, and safe application of diverse metal and metal oxide nanoparticles—including selenium, silver, copper oxide, manganese oxide, magnesium oxide, chromium oxide, aluminum oxide, zinc oxide, carbon quantum dots, and graphene quantum dots—and their physiological impacts on numerous freshwater fish species. A major focus of his work is the incorporation of nanoparticles into fish diets to enhance growth performance, haematological and biochemical responses, antioxidant activity, and overall aquatic health, helping advance the emerging field of nanonutrition. He contributes significantly to the development of green-synthesized nanoparticles using plant extracts and waste-derived materials, assessing their antibacterial, larvicidal, and biomedical potentials, as well as their suitability for aquaculture applications. His studies also address key environmental challenges, including wastewater toxicity, tannery effluent pollution, and eco-friendly remediation strategies, while other works explore the role of probiotic gut microbiota in improving fish immunity and disease resistance. With 44 scientific publications and more than 220 citations, Prof. Dr. M. R. Rajan research offers valuable insights into sustainable aquaculture practices, nanoparticle biosafety, environmental health, and innovative nanobiotechnological solutions for aquatic systems.
