Carbon Based Quantum Dots: Sensing, Imaging and Beyond

Abstract

Sensors detect the presence of molecules or substances by converting various stimuli into useful signals. Carbon quantum dots (CDs) are particularly effective for sensing due to their remarkable properties, which include chemical stability, low cost, high sensitivity, excellent luminescence, real-time detection capabilities, and rapid response times. Therefore, the design and synthesis of various CDs-based sensors using simple, mild, and cost-effective methods is crucial. However, challenges such as aggregation tendencies and low quantum yields in CDs require further modifications to enhance their effectiveness in sensing applications. In this presentation, our recent work on the fabrication of metal-integrated carbon dots, related hybrid materials, and their potential biomedical applications will be discussed.
