Biofilm inhibition (%) as a function of time, by MET/DOX gel, calculated as a percentage UV absorbance with respect to a negative control, i.e., the absorbance of a biofilm grown in broth without antibiotics released from Met/Dox gel. Bars represent the mean ± SD of triplicate results with separately grown bacteria ( with respect to the negative placebo control).
