摘要:
量子点是一种准零维的纳米材料,具有许多优异的光学性能,如宽激发、窄发射、强度高、寿命长、抗漂白等。因此,其作为离子探针具有灵敏度高、设备简单、重现性好、可用于现场快速检测等优点。本文综述了量子点作为荧光离子探针在金属离子、阴离子、小分子等检测方面的应用进展。
Abstract:
Quantum dots (QDs), a sort of quasi zero-dimensional (0-D) nanomaterials, possess numerous ex-cellent optical properties, such as wide excitation, narrow emission, strong intensity, long lifetime, and stable fluorescence etc. Therefore, QDs as fluorescence ion probes show many advantages like high sensitivity, simple instrument, excellent repeatability, and rapid spot detection. This paper reviews the recent advances of QDs as fluorescence ion probes in applications of detecting metal ions, anions, and small molecules etc.
