Vancomycin release from ECnVs tethered in (A) collagen or (B) co-gel matrix. (C) Release profile were fitted by first-order kinetics from 0 to 8 h (solid line) and Kormeyer-Peppas model from 8 h to 96 h (dotted line). Ki = first order constant, Kkp = Korsmeyer release rate constant, and n = diffusional exponent. Each data represents mean ± standard deviation for n=4. The statistical difference of Ki states *p<0.05.
