荧光纳米粒子是指可以发荧光的量子点或将荧光团通过包埋、共价键连接以及超分子组装等方式引入有机或无机纳米粒子中,使其可在特定条件下产生荧光效果。因其与传统染料相比更高的荧光亮度、更强的稳定性、分散性以及生物相容性,荧光纳米粒子已广泛应用于检测、标记等工作中。分析了3种荧光纳米粒子——无机粒子、有机共轭型粒子以及有机非共轭型粒子,分别对其合成、应用进行阐述分析,以指导应用于航空领域的研究。
Fluorescent nanoparticles refer to quantum dots that can fluoresce or to organic or inorganic nanoparticles into which fluorophores are introduced by means of embedding,covalent bonding and supramolecular assembly,enabling them to produce fluorescence effect under specific conditions.Fluorescent nanoparticles have been widely used in detection,labeling and other work because of their higher fluorescence brightness,stronger stability,better dispersion,and superior biocompatibility compared with traditional dyes.In this paper,three kinds of fluorescent nanoparticles—inorganic particles,organic conjugated particles and organic non-conjugated particles were analyzed,and their synthesis and applications were expounded and analyzed to guide future research and applications in the field of civil aviation.
