Abstract This study introduces the synthesis of nitrogen-doped carbon dots (N-L-Ser-CDs) from L-serine and urea through a straightforward economical one-step solid-phase pyrolysis process. The incorporation nitrogen into resulted in remarkable 27.6-fold increase fluorescence intensity, featuring peak emission at 405 nm when excited 330 significant quantum yield 22.5%. These N-L-Ser-CDs displayed specific binding affinity for Cu2+, leading to pronounced quenching effect. However, upon interaction with glutathione (GSH), + Cu2+ complex was selectively restored. restoration attributed displacement surface due strong between GSH Cu2+. mechanism underlying this elucidated as an electron transfer process state Additionally, sensor developed exhibited linear detection range 0–90 µM limit 3 µM, 0-120 GSH. By integrating capabilities both GSH, successful logic-gated fluorescent probe developed. Most importantly, proposed method offers simplicity, affordability, ease use, while also showing potential practical real urine samples.

Abstract Carbon dots (CDs) with intrinsic bioactivities are candidates for bioimaging and disease therapy due to their diverse bioactivities, high biocompatibility, multiple functionalities in multimodal theranostics. It is a multidisciplinary research hotspot that includes biology, physics, materials science, chemistry. This progress report discusses the CDs applications The relationship between synthesis structure of summarized analyzed from material chemical perspective. including anti‐tumor, antibacterial, anti‐inflammatory etc. discussed biological points view. Subsequently, optical electronic properties can be applied biomedical field physical Based on functional review CDs, reviewed, diagnosis treatment, activity, Unlike previous reviews, this combines disciplines gain more comprehensive understanding mechanisms, functions, bioactivities.
