Fig. 10From: Polydopamine-Based Composite Nanoparticles with Redox-Labile Polymer Shells for Controlled Drug Release and Enhanced Chemo-Photothermal TherapyConfocal fluorescence images of live A549 cells treated with PBS, PDA@PMAA-1 nanoparticles, DOX-loaded PDA@PMAA-1 nanoparticles, and free DOX with or without NIR laser irradiation (λ = 808 nm, 5 W cm−2) for 300 s. Live cells were stained with Calcein-AM (green). The scale bar is 50 μmBack to article page
