a Fluorescence intensities of main organs and tumors after injection of APP NPs (n = 3). b In vitro PA images and fitted relationship between PA signal values versus different concentrations of APP NPs (25, 50, 100, 200, 400 µg mL−1). c Quantitative PA values and (d) in vivo PA images of tumors after intravenous administration of APP NPs at different time intervals. e Ultrathin sections of tumor tissue at various time points postinjection of APP NPs detected by fluorescence microscopy (scale bar: 50 μm). f–h Biochemical indicators of liver and kidney functions, including aspartate aminotransferase (AST), alanine aminotransferase (ALT), and blood urea nitrogen (BUN), of mice postinjection of APP NPs for 0, 1, 7, and 14 days (n = 3)
