摘要
量子点因其具有独特的物理和化学性质（如激发光谱宽、发射光谱窄，而且可通过改变量子点内核心材料的尺寸大小对其发射光波长进行调频等）被作为一种新型的荧光标记物在生物医学中获得广泛使用。就量子点的光学特性及其在生物、医学等方面的最新研究进展及应用前景进行简要综述，同时讨论了量子点存在的细胞毒性等主要问题。
Quantum Dots （QDs） with its unique optical properties including broad-range excitation, size- tunable narrow emission spectra and the adjustable emission wavelength by changing the size of core composition, is widely applied in biomedicine as a fluorescent marker in recent years. This paper focuses on the review of the characteristic of ODs, the prospects of its applications in biological and medical areas and the latest research development.Moreover, key issues including the potential toxicity of ODs are discussed.
