摘要:

对细胞器及其微环境的时空动态分析是理解细胞生命活动的关键. 传统荧光染料存在高浓度猝灭及光稳定性差等局限, 难以满足长时程、 高信噪比的活细胞成像需求; 基于此, 聚集诱导发光(Aggregation-induced emission, AIE)材料被开发并展现出独特优势.本文系统总结了AIE分子探针的设计策略及其在线粒体、 溶酶体、 脂滴、 细胞膜、 细胞核、 内质网和高尔基体等细胞器成像方面的应用, 分析了超分辨成像、 近红外AIE探针的分子设计、 跨物种成像、 逻辑响应和毒性评估等方面所面临的挑战, 并展望了AIE分子探针细胞器成像的未来发展.

Abstract:

The spatio-temporal analysis of organelles and their microenvironments is pivotal to understanding cellular life processes. Conventional fluorescent dyes suffer from limitations such as quenching at high concentrations and poor photostability, rendering them unsuitable for long-term, high signal-to-noise ratio live-cell imaging. Aggregation-induced emission(AIE) materials have emerged to address these challenges, demonstrating unique advantages. This paper systematically summarises design strategies for AIE molecular probes and their imaging applications in organelles including mitochondria, lysosomes, lipid droplets, cell membranes, nuclei, endoplasmic reticulum, and Golgi apparatus. It identifies challenges in super-resolution imaging, molecular design of near-infrared AIE probes, cross-species imaging, logic response, and toxicity assessment, while outlining future directions for organelle imaging with AIE molecular probes.

Key words: Aggregation-induced emission, Molecular probe, Organelle imaging
