CAT and abscess: Figure 7C shows representative photographs of MRSA-infected subcutaneous abscess within 11 d of treatment in the 4 groups, and the corresponding graphical representations of the quantitative measurement of abscess areas are presented in Fig. 7D. It was found that the mice treated with CAT–Ce6 NCs showed much faster scarring and small abscess areas compared to the other 4 groups during the entire treatment.
