Fluorescence sensing of glucose at nanomolar levels using an imprinted copolymer embedded with carbon quantum dots.

ABSTRACT: Monitoring glucose levels in intracellular fluid is important in healthcare, as it directly correlates with cell metabolism-related diseases. However, conventional methods typically require high-end equipment and can only be performed in laboratory settings. In this study, an imprinted copolymer composed of 3-aminopropyltriethoxysilane and tetraethyl orthosilicate, embedded with carbon quantum dots (CQDs), was developed for fluorescence-based glucose sensing. A facile preparation method yielded CQDs with sizes ranging from 0.7 to 5 nm and fluorescence emission at a wavelength of 435 nm. These CQDs were incorporated into a polymeric matrix in the presence of glucose, followed by a molecular imprinting process. The resulting polymeric particles exhibited a diameter of approximately 604 ± 15
