【摘要】 基于聚集诱导发光(AIE)机制的生物传感器具有灵敏度高、高量子产率、便于合成等优点,所以具有AIE特性的有机小分子得到了科研工作者的广泛关注.随着对AIE分子结构和理论知识的深入认识,针对细胞或微生物结构特点设计合成的可与细胞或微生物特异性结合的有机荧光分子,可准确、便捷、有效地实现对细胞或微生物的成像和靶向药物递送,对扩展有机分子探针的生物应用具有重要的推动作用.本文将重点阐述近几年具有AIE特性的四苯乙烯衍生物荧光分子在细胞和微生物识别成像,靶向递送和抗菌性能方面的应用,为后续研究工作提供借鉴和指导.更多还原

【Abstract】 Aggregation-induced emission(AIE) probes show high sensitivity, high quantum yield and can be synthesized conveniently. Organic molecules with AIE characteristics have attracted much attention from scientists. With the exploration of molecular structure and theoretical knowledge of AIEs, the developed probes can image cells and microbes selectivity, and deliver drugs effectively, which has an important role in promoting the biological application of organic molecular probes. In this review, we focus on the application of tetraphenylethylene derivatives with AIE characteristics in cell and microbial recognition imaging, targeted delivery and antibacterial properties in recent years,and provide references for the follow-up research work.更多还原
