About me

Debolina Ghosh is a PhD research scholar in the Centre for Environment,Indian Institute of Technology (IIT) Guwahati, India. She received her undergraduate and postgraduate degree in Biotechnology from the School of Biotechnology, Kalinga Institute of Industrial Technology (KIIT), Bhubaneswar, Odisha in 2020. She has a fervid interest in translational research specifically designed for environmental-related challenges and their targeted remedial applications. She believes a strong foundation is key and devotes most of her time to reviewing literature across various interdisciplinary fields trying to identify research gaps and new opportunities. Her primary goal is to explore and diversify her existing knowledge to address global environmental issues and bring about significant and tangible benefits to the real world. During her M.Tech dissertation, she actively worked on wastewater treatment using adsorption, bioremediation, photocatalyst-mediated organic material degradation and other allied techniques. This eventually led her to explore wastewater treatment as her primary area of research interest. Debolina is a recipient of the prestigious Prime Minister's Research Fellowship (PMRF), awarded to the country's excellent doctoral candidates for pursuing their research.

Research

In the last decade, there have been tremendous efforts in designing effective chemosensors for designing a quick and reliable, robust testing system to detect crucial environmental analytes and their targeted remediation techniques. Fluorescent polymer gels or fluorescent hydrogels are generally known to be light-emitting, which showcases this type of material with advanced applications in the field of environmental sensing and chemical sensing applications. Quinoxaline derivatives are naturally representative fluorophores. When embedded in the polymeric gel skeleton, it can lead to predominant fluorescence. Hydrogen bonding, pi-pi stacking interactions, and Van der Waals forces may enable the probe to form a crosslinked network in the polymeric backbone, thereby leading to the formation of a hydrogel. Even though there is research on fluorescent hydrogels using different fluorophores, no significant research output is observed with respect to incorporating a quinoxaline derivative fluorophore probe molecule into a polymeric hydrogel matrix targeted at several wastewater sensing applications. Based on this my primary research domain includes:-

  • Design and Synthetis of Fluorescent Hydrogel based Chemosensors
  • Sensing of Pollutants
  • Remediation of Pollutants
