能够稳定地与带负电荷的核酸结合,从而提高了基于肽的纳米材料的载荷能力,靶向能力和转染的效率,并使材料能够实时成像。近几十年来,已经广泛研究了传统的use液分子,但是由于聚集引起的淬火(ACQ)效应,它们的排放可能会在高浓度下弱化。95,96在2001年,Tang和他的同事提出了聚集诱导的发射(AIE)的概念,以说明一系列在高度聚合状态下发出强效的效应分子。97 Di ff erent from the case of uorescent molecules a ff ected by the ACQ e ff ect, for AIE lumi- nogens (AIEgens) there is no need to control their concentration during use and they can emit uorescence in the aggregated state, and some AIEgens have photosensitivity, so they are widely used in bioimaging, 98 – 101 biosensing 102,103和生物疗法的ELD。104 - 109我们的小组审查了一些基于AIE的材料的应用。110 - 112
