(A) In vitro CT images of AuNC@DHLA with various concentrations. (B) CT values in Hounsfeild unit (HU) of AuNC@DHLA as a function of concentration. (C) CT images of a tumor bearing C57BL/6j mouse before and after intratumor injection with AuNC@DHLA (10.0 mg mL-1, 100 μL) at 8 h. The CT contrast was obviously enhanced in the mouse tumor (red dashed circle). Scale bar: 1 cm.
