Carbon Quantum Dots for Biomedical and Environmental Applications

This book provides a comprehensive examination of carbon quantum dots (CQDs), emphasizing their significant and multifaceted roles in biomedical and environmental applications. It encompasses a wide range of topics, beginning with the latest advancements in synthesis techniques, from bottom-up and top-down methods to green and scalable approaches, that influence the size, morphology, and surface chemistry of CQDs. A major focus is on functionalization strategies, which have been critical in tailoring surface properties of CQDs to enhance their selectivity, sensitivity, and stability for specific applications. • Encompasses both fundamental science and applied research. • Examines chemical doping, surface passivation, and conjugation with biomolecules or other nanomaterials to improve their performance in biological environments and environmental matrices. • Explores the use of CQDs in bioimaging, biosensing, targeted drug delivery, and phototherapy, highlighting their role in improving disease diagnosis and therapeutic efficacy while minimizing the side effects. • Discusses practical environmental applications such as pollutant detection, photocatalytic degradation of organic contaminants, heavy metal sensing, and water purification. • Serves as a guide to the current state and prospects of CQDs, fostering multidisciplinary engagement and inspiring novel approaches to harness their full potential. This book equips researchers, advanced students, and industry professionals in materials science and engineering and chemistry with the knowledge necessary to innovate and develop next-generation CQD-based technologies that address major challenges in healthcare and environmental sustainability.
