Comparison of the cytotoxic effect and anti-inflammatory effect of NCs to RAW264.7, including DL-DHLA-AuNCs, R-DHLA-AuNCs, DL-DHLA-AuNCs-Zn, and R-DHLA-AuNCs-Zn: a RAW264.7 cells. b The western blot analysis (b) and semiquantitative analysis of IL-1β (c) and TNF-α (d) *P < 0.05;**P < 0.01;***P < 0.001; Data presented as mean ± SD. (n = 6 /group); Con indicated the culture of only RAW264.7 cells after 24 h; LPS represented the RAW264.7 cells were tested by LPS-stimulation after 24 h; Others represented RAW264.7 cells were pre-stimulated by LPS and then cultured with various agents after 24 h
