AuNCs@SiO₂-FA nanoprobes for fluorescence imaging. (a) In vitro fluorescence image of AuNCs@SiO₂-FA in 0.01 M PBS with different concentrations; (b) In vivo fluorescence image of 50 uL AuNCs@SiO₂-FA injected subcutaneously at three different doses (area-1: 56 mg/mL; area-2: 112 mg/mL; area-3: 226 mg/mL) into the left mice. The left mice without injection was selected as control; (c) fluorescence image of tumor tissues with tail vein injection at the concentration of 287 mg/mL at 6 h postinjection.
