Cell survival fraction of S. aureus (A) and P. aeruginosa (B) biofilm treated with HCT hydrogels-mediated PDI. Biofilm cells were incubated with 20 μM TBO or HCT hydrogels containing 20 μM TBO for 1 h, followed by light exposure at 20 J·cm−2. Each value is the mean from three independent experiments ± standard deviation. * p < 0.05.
