Recent Advances in Carbon Dot-based Fluorescent Probes for Detection of Heavy Metal Ions
重金属离子污染对生态环境和人类健康构成严重威胁.目前常用的重金属离子检测技术存在成本高、操作复杂且耗时费力等局限性,因此迫切需要发展低成本、简便和高效的新型检测技术.碳点(CDs)荧光探针作为一种基于碳量子点的荧光检测工具,凭借其独特的光学特性、良好的生物相容性及低毒性等优势,在重金属离子检测领域展现出广阔的应用前景.作为新兴纳米材料,CDs荧光探针已成功应用于Fe3+、Cu2+、Pb2+、Hg2+及Zn2+等重金属离子的检测.本文综述了近3年来基于CDs的荧光探针用于上述重金属离子检测的研究进展,归纳了其检测机理,并探讨了其当前面临的主要挑战及未来的发展方向.
Heavy metal ion pollution severely impacts the ecological environment and human health,making the sensitive and specific detection of heavy metal ions an urgent priority.Currently,commonly used detection methods for heavy metal ions are costly,time-consuming,and labor-intensive,highlighting the critical need to develop low-cost and user-friendly approaches for detecting heavy metal ions.Carbon dots(CDs)exhibit advantages such as unique optical properties,good biocompatibility,and low toxicity.As an emerging nanomaterial,CDs-based fluorescent probes have been used for detection of heavy metal ions.This review focused on the applications of CDs-based fluorescent probes in heavy metal ion detection.It introduced the sensing mechanism of CDs and summarized the research progress reported in the past three years on detection of heavy metal ions such as Fe3+,Cu2+,Pb2+,Hg2+,and Zn2+using CDs.In addition,the main challenges and future development directions of CDs-based fluorescent probes were discussed.
