摘要
随着细菌感染和抗生素耐药性形势越来越严峻,对开发快速、简单、灵敏的细菌检测和成像技术的需求越来越迫切。使用天然原料或者将低价值废弃物为原料得到的生物质碳点,不仅保留了传统半导体量子点优异的光电特性,还具有更好的生物相容性、更低的制备成本以及绿色环保的合成方法,符合未来能源可持续发展的趋势。生物质碳点已在细菌成像和检测上表现出极大的潜力,但面对如此丰富的生物质来源,如何选择合适的碳源并结合生物质碳点的优点构建效果更好的细菌成像和检测方法仍存在问题。本篇综述梳理了生物质碳点的种类,概述了生物质碳点在细菌成像和检测中的应用,对生物质碳点作为成像和检测传感器的不足进行了分析,希望为开发出更符合需求的成像探针和更有效的检测方法提供参考。
As the more serious bacterial infections and increasing bacterial antibiotic resistance,the development of fast,simple,and sensitive bacterial detection and imaging technologies is the need of the hour.Biomass-based carbon quantum dots obtained from natural raw materials or from low-value waste materials not only retain the excellent properties of semiconductor quantum dots,but also have better biocompatibility,lower cost,and green synthesis methods,which are in line with the future trend of sustainable energy development.Biomass-based carbon quantum dots have already shown great potential in bacterial imaging and detection,but facing with such an abundant biomass,how to select a suitable carbon source to construct a more effective bacterial detection and sterilization method is still a problem.In this review,we summarized the types of biomass-based carbon quantum dots,and the latest development in the application of bacterial imaging and detection.We also analyze the shortcomings of these applications,in order to help for the development of super imaging probes and more effective detection methods.
