摘要
量子点是半径小于或接近于激子玻尔半径的一类半导体纳米晶,作为一种新型的荧光标记物,其独特和可调谐的光学特性(宽的激发光谱、窄的发射光谱、可精确调谐的发射波长以及可忽略的光漂白等)使其在生物和医学方面显示出巨大的应用潜力。近年来量子点在定量分析方面的应用也取得了很大进展,为分析化学的含量测定提供了一种新的方法和技术,显示出极大的优越性。本文就量子点在金属离子和药物等的含量测定方面国内外的研究进展进行了综述。
Quantum dots (QDs) arc a kind of semiconductor nanopaticles with the radius equal to or less than the exciton Bohr radius. They have tremendous potential in the field of biology and medicine because of their unique and tunable optical properties (broad excitation spectrum, narrow emission spectrum, precise tunability of their emission peak and negligible bleaching, etc) as new fluoresent probes. Recently, because of their superiority in sensitivity, a new method based on them is introduced to analysis, and made great progress in the quantitative analysis. Here the applications of QDs in the assay of metal ions, some drugs and compounds, as well as the current research progress arc reviewed according to the advanced works worldwide.
