Great advances have been made in sensor-based methods for chemical analysis owing to their high sensitivity, selectivity, less testing time, and minimal usage of chemical reagents. Quantum Dots (QDs) having excellent optical properties have been thoroughly explored for variety of scientific applications wherein light plays an important role. In recent years, there have been an increasing number of publications on the applications of QDs as photoluminescent nanosensors for the detection of chemicals and biomolecules. However, there has been hardly any publication describing the use of QDs in the detection of various toxic chemicals at one place. Hence, a literature survey has been made on the applications of QDs as chemosensors for the detection of gaseous, anionic, phenolic, metallic, drug-overdose, and pesticide poison so as to open a new perspective towards the role of sensors in analytical toxicology. In this review, the QD-based analysis of biospecimens for poison detection in clinical and forensic toxicology laboratories is highlighted.

量子点作为用于检测有毒物质的纳米传感器：文献综述。

由于基于传感器的化学分析方法的高灵敏度，选择性，较少的测试时间和最少的化学试剂使用量，因此已取得了巨大的进步。具有出色光学性能的量子点（QD）已被广泛探索，其中光起着重要作用的各种科学应用。近年来，越来越多的出版物将量子点作为光致发光纳米传感器用于化学物质和生物分子的检测。但是，几乎没有任何出版物描述在一处检测各种毒性化学物质时使用QD的情况。因此，已经进行了有关QD作为化学传感器用于检测气态，阴离子，酚类，金属，药物过量的化学传感器的研究，和农药中毒，从而为传感器在分析毒理学中的作用开辟了新的视角。在这篇综述中，重点介绍了基于QD的生物标本在临床和法医毒理学实验室中进行毒物检测的分析。
