Abstract: Carbon quantum dots (CQDs) have emerged out as potential competitor to semiconductor QDs, and are quasi-spherical nanoparticles consisting of amorphous to nano-crystalline cores. The excellent features in terms of high chemical stability, low-cost synthesis, easy scalability, environmental friendliness, broadband optical absorption, low toxicity, strong photoluminescence (PL) emission, and optical properties make them a potential material in photo-catalysis, bio-sensing, drug delivery, chemical sensing, bio imaging and electro-catalysis domain. Herein, we present them as sensitive and selective sensor material for toxic heavy metals & metalloids (Arsenic, Selenium & Chromium) detection in water below WHO guidelines. The surface of as synthesized CQDs is modified with appropriate ligand and assays are established for their application toxic metals/metalloids determination in water. The developed sensor interface is fully characterized in terms of its structural (HR-TEM, XRD, SEM, etc.) and optical (UFS, XPS, PL, UV-Vis, Raman) properties. Besides, the technical parameters have been extracted to design a portable optical system for on-site detection of these pollutants in water, which is the present need. The in-vitro toxicity study of CQDs is also conducted to understand their toxic effect before environmental application deployment.

Biography:
Dr. Pooja is a Senior Principal Scientist at CSIR-Central Scientific Instruments Organisation (CSIR-CSIO) and honorary Professor with Academy of Scientific and Innovative Research (AcSIR), New Delhi. She did her M. Tech from IIT Roorkee and PhD from AcSIR, New Delhi. Her research focuses on the design of Materials for hydrogen production, water/air pollutants degradation, and monitoring of environmental contaminants. Dr. Pooja has an impressive portfolio of over 102 research papers published in high-impact journals, and 23 book chapters. She has edited 7 books as lead editor, filed 4 patents, secured 2 design registrations, and 2 copyrights/trademarks. She has developed 4 technologies, with 2 successfully transferred to industry.
Her contributions to science have been recognized through numerous prestigious awards, including the TWAS Young Affiliate (2025), IIT Roorkee Distinguished Young Alumni Award (2024), NASI Young Scientist Platinum Jubilee Award (2021), INAE Young Engineer Award (2020), SERB Women Excellence Award (2020), IEI Young Engineer Award, and Haryana Yuva Vigyan Ratan Award (2019) among others. She has been honored with international fellowships such as the CSIR Raman Research Fellowship to visit Drexel University, USA; IUSSTF Water Advanced Research and Innovation (WARI) Fellowship, and the Canadian Commonwealth Fellowship. Dr. Pooja is also an active member of several national and international science academies, including the Global Young Academy (Germany), Indian National Academy of Engineers, Indian Academy of Sciences, National Academy of Sciences, and Indian National Young Academy of Sciences. She has represented India in BRICS Young Scientist Conclave and the SCO Young Scientist Conclave. Recently, she was recognized among the Eminent 125 Women in Science by the CII Compendium and listed in the top 2% of researchers globally, according to a Stanford University and Elsevier study in 2022, 2023, 2024. She is also prolific orator and delivered more than 72 talks at national and international platform, and is coordinating science outreach activities in Chandigarh and Haryana schools at her institute level.
