摘要

碳量子点(Carbon Quantum Dots

CQDs)是一种新型的碳纳米材料

因其强的量子限域效应和稳定的荧光性能等一系列优异性能

吸引了化学、物理、材料和生物等各领域科学家的广泛关注。相比传统半导体金属量子点

CQDs还具备优异的低毒性和生物相容性

更拓宽了其在生物领域内的研究前景。本文简要地介绍了CQDs的制备方法

主要包括自上而下和自下而上两个方向。除此之外

本文综述了CQDs突出的物理化学性质和性能

包括CQDs的荧光性能、生物相容性和上转换效应

并对CQDs在其在生物成像上的应用进行了归纳。

Abstract

Carbon quantum dots (CQDs)

a novel class of carbon nanomaterials

have received wide attention due to their strong quantum confinement effect and stable photoluminescence property. Compared with traditional metal quantum dots

CQDs also show relatively lower toxicity and better biocompatibility for potential biological applications. Brief introductions of synthetic methods are summarized here

focusing on two main directions: top-down route and bottom-up route. The prominent physicochemical properties including photoluminescence

low toxicity and up-conversion photoluminescence are reviewed in details. Furthermore

current applications in bioimaging are introduced in the review.
