Antimicrobial properties of the iFBH system. S.aureus survival rate as the percentage to the negative control (growth medium alone), CHRG01, ABU, TEMP-A, and ALA5-conjugated PEGMC, pristine PEGMC, commercial dressing (Hydrofera Blue), and ampicillin (AMP)-loaded PEGMC (positive control). ABU and TEMP-A-conjugated PEGMC and PEGMC-AMP showed a significant decrease compared to the negative control (*, p<0.05, compared to control).
