architecture allows investigation of environmental sensitivity apart from providing excellent ability to target sub-cellular organelles. The synthesized fluorophores showed low cytotoxicity and excellent localization within the lipid droplets. Further, the fluorophores were also utilized to study viscosity changes within the LDs induced by Nystatin. More importantly, we also demonstrate imaging of LDs in multi-cellular
荧光探针为可视化脂滴 (LD) 的动态形态和研究它们的生理相互作用提供了非常有效的工具。在这项工作中,我们利用带有腈和酯取代基的溶剂化显色香豆素探针进行活细胞成像。荧光探针的特征在于供体(二乙氨基)和受体(腈和/或酯)取代基和可旋转的双键。设计的架构除了提供针对亚细胞细胞器的出色能力外,还允许研究环境敏感性。合成的荧光团在脂滴内显示出低细胞毒性和出色的定位。此外,荧光团还用于研究制霉菌素诱导的 LD 内的粘度变化。更重要的是,C. 线虫。
