Abstract

The present disclosure relates to Near-infrared fluorescent indicators for lysosomes and application thereof. These indicators are composed of lipophilic NIR BODIPY derivatives and ionizable bis-tertiary amine moiety, which enable the formation of a transient amphiphilic state in acidic environments specifically. This structural feature affords accurate lysosomal membrane targeting ability at nanomole staining concentration.
