Efficiency of biofilm inhibition of AuNPs, indolicidin, and AuNPs–indolicidin at intermediate (24 h biofilm) stages of development. Biofilm viability was quantified by the XTT assay. Data are reported as the mean±SD of three independent experiments. Statistically significant differences between groups: *p<0.05, **p<0.01 (Student’s t-test).
