Abstract:
A dual responsive NIRF turn-on protein delivery system incorporating an NIRF turn-on probe and protein into one single nanoparticle has been constructed. It can be taken up efficiently by A549 cells, where protein release and NIRF recovery happen simultaneously in response to low pH and excessive H2O2. This work provides a novel system for monitoring intracellular protein delivery.
