(a) Molecular structures for the ratiometric aza-BODIPY PA responsive Cu(II) probes reported by Li et al. (185). (b) PA images of 72 (10 μM in PBS + 0.1% Cremophor EL, pH 7.4) in fluorinated ethylene propylene tubing overlaid with a 1 cm thick phantom treated with 0 and 10 equiv of Cu(II), with excitation at 767 nm. Highest and lowest intensity PA amplitudes are indicated by white and black, respectively. Scale bar represents 2 mm. Reproduced with permission from ref. 185.
