Biocompatibility of AuNCs. A The viability of PDLCs treated with AuNCs of different concentrations was measured by CCK-8 at 48 h. B Live/dead staining of PDLCs treated with AuNCs (0.4 mM) for 48 h. The green fluorescence of the calcein probe indicates live cells, and red fluorescence of PI indicates dead cells. C H&E-stained images of liver and kidney collected from mice after different treatments. Con treatment with PBS, Lig ligature and treatment with PBS, Fn ligature with F. nucleatum inoculation, AuNCs ligature with alternate applications of F. nucleatum and AuNCs (0.4 mM)
