(a) In vitro PAI of MDA-MB-231 cells incubated with various concentrations of IR-CS–PPy NCs using PAI system with 532–1000 nm wavelength and 625–1000 nm wavelength. (b) Representative digital photographs of MDA-MB-231 tumor-bearing nude mice for in vivo PAI. The white dash lines indicate the tumor area. (c) In vivo PAI of tumor tissues in MDA-MB-231 tumor-bearing nude mice at 0, 6, and 12 h after injection of IR-CS–PPy NCs (100 μL) using PAI system with 532–1000 nm wavelength, and 625–1000 nm wavelength. (d) Representative 3D PA images of tumor tissues MDA-MB-231 tumor-bearing nude mice at 0, 6, and 12 h after injection of IR-CS–PPy NCs using PAI system with 532–1000 nm wavelength.
