Self-assembly of nanoparticles by human serum albumin and photosensitizer for targeted near-infrared emission fluorescence imaging and effective phototherapy of cancer
highly sensitive and selective ratiometricfluorescentprobe for Fe2+ was developed by linking an Fe2+‐insensitive fluorophore to an Fe2+‐sensitive reporter–fluorophore fragment. The fluorescence intensity ratio increased linearly with the concentration of Fe2+ (see scheme). The probe was applied to the ratiometricimaging of intracellular and adscititious fluctuations of Fe2+ in live HL‐7702 and HepG2
