研究目的
Investigating the synthesis of yellow emissive nitrogen-doped graphene quantum dots (N-GQDs) for Fe3+ sensing and bioimaging applications.
研究成果
The synthesized N-GQDs exhibit high fluorescence quantum yield, favorable biocompatibility, and strong resistance to photobleaching, making them suitable for Fe3+ detection in natural water and cellular imaging. The detection limit of 63 nM demonstrates high sensitivity and selectivity for Fe3+.
研究不足
The study focuses on Fe3+ detection and bioimaging, potentially limiting its applicability to other metal ions or broader sensing applications.
