Figure 3. Bacterial killing, EPS degradation and biofilm disruption by the combination of CAT-NP and H2O2.
a , Viability of S. mutans within CAT-NP treated-biofilms 5 min after H2O2 exposure. b, EPS degradation within biofilm 30 min after H2O2 exposure. c, Degradation of insoluble glucans produced by GtfB and soluble glucans from GtfD. Data are shown as mean ± s.d. *P< 0.001 (vs. control).
