Biomass-waste derived Quantum Dots nanocomposite-based electrochemical sensor for detecting emerging pollutants

Emerging contaminants (ECs) have become a significant environmental concern due to their widespread presence and risks to health and ecosystems. Meanwhile, agricultural waste is also increasing, providing a valuable source for high-value materials. Traditional detection methods are costly, slow, and require specialized equipment and time-consuming laboratory analyses. Electrochemical sensors offer a low-cost, rapid, and sensitive alternative for EC detection and remediation. This project aims to develop innovative electrochemical sensors using carbon quantum dots (CQDs) and bacterial cellulose (BC), both sustainably derived from biomass waste. These nanomaterials together provide excellent conductivity, large surface area, and biocompatibility, improving sensor performance for detecting and degrading ECs. The research will tackle challenges in synthesizing quality carbon nanomaterials and integrating them into polymer matrices to create stable, efficient, and eco-friendly sensors. This sustainable project will benefit both host and home institutions by advancing their expertise in green synthesis and environmental sensing. By applying waste-derived nanomaterials, the collaboration will strengthen knowledge in sustainable technologies and circular economy principles. The partnership will also promote knowledge exchange, joint publications, and long-term cooperation, driving innovations to address global environmental challenges.
