摘要

碳点(CDs)作为一种新型的零维碳基纳米材料，由于其优异的荧光性质、良好的生物兼容性、低细胞毒性以及丰富的表面官能团等性质，在荧光传感和生物医学领域具有巨大的应用潜力。特别是针对肿瘤弱酸性的微环境特点，设计pH响应型碳点来实现对肿瘤的特异性治疗将尤为重要。本文对近年来基于pH响应型碳点的研究工作进行了系统的调研，综述了pH响应型碳点的荧光机制及其在pH传感、生物成像及癌症治疗等生物医学领域的应用，并对pH响应型碳点目前面临的主要挑战以及未来发展的方向进行了展望。

Abstract

As a new type of zero-dimensional carbon-based nanomaterials

carbon dots(CDs) have a great application potential in the fields of fluorescence sensing and biomedicine due to their excellent fluorescence properties

good biocompatibility

low cytotoxicity

and large surface functional groups. Especially given the weakly acidic microenvironment characteristics of tumors

it is crucial to design pH-responsive carbon dots to achieve specific treatment. This article has conducted a systematic investigation on the research work based on pH-responsive carbon dots in recent years and reviewed the fluorescence mechanism of pH-responsive carbon dots and their applications in biomedical fields such as pH sensing

bioimaging

and cancer treatment. Finally

the main challenges currently faced by pH-responsive carbon dots and the future development direction have been prospected.
