Abstract:
Detecting environmental contaminants is crucial for protecting ecosystems and human health. While traditional carbon dot (CD) fluorescent probes are versatile, they may suffer from limitations like fluctuations in signal intensity, leading to detection inaccuracies. In contrast, ratiometric fluorescent probes, designed with internal self-calibration mechanisms, offer enhanced sensitivity and reliability. This review focuses on the design and applications of ratiometric fluorescent probes based on CDs for environmental monitoring. Our discussion covers construction strategies, ratiometric fluorescence principles, and applications in detecting various environmental contaminants, including organic pollutants, heavy metal ions, and other substances. We also explore associated advantages and challenges and provide insights into potential solutions and future research directions.
摘要:
检测环境污染物对于保护生态系统和人类健康至关重要。传统的碳点(CD)荧光探针用途广泛,它们可能会受到信号强度波动等限制,导致检测不准确。相比之下,比率荧光探针,设计有内部自校准机制,提供增强的灵敏度和可靠性。本文重点介绍了基于CD的比例荧光探针在环境监测中的设计和应用。我们的讨论涵盖了建筑战略,比率荧光原理,以及在检测各种环境污染物中的应用,包括有机污染物,重金属离子,和其他物质。我们还探索相关的优势和挑战,并提供对潜在解决方案和未来研究方向的见解。
