An effective approach to develop targetable and responsive fluorescent probes for imaging of organelles based on cresyl violet scaffold

Xiaoyi Li et al.

Summary: Fluorescent probes combined with confocal microscopy are a powerful tool for imaging living cells and organelles, but there is a lack of a predictable method for designing such probes. In this study, a synthetic strategy based on the cresyl violet scaffold was proposed to construct targetable and responsive probes for organelles.
