(A) Viability count (log10) of non-irradiated biofilm cultures (non-PDT) and PDT-treated (LED light at 113 J.cm−2, 5 min) by different groups. (B) Determination of SOSG fluorescence emission of Hy.NLC-HG. Free RB/non-PDT = positive control, ** p < 0.01, *** p < 0.001, compared between the treatment and the PBS control groups.
