Abstract

Silk fibroin films incorporated with tetracycline was prepared and characterized by Fourier-transform infrared spectrometer and differential scanning calorimeter and examined antibacterial effect. The conformation of silk fibroin was changed from random coil to $\hat{a}$ sheet structure with incorporation of tetracycline. Antibacterial activity of the materials was evaluated against Gram-negative bacteria (Escherichia coli) and Gram-positive bacteria (Staphylococcus epidermis, and Staphylococcus aures) using agar plate method showing clear inhibition zone around tetracycline silk film. It is concluded that tetracycline-incorporated SF films are highly effective against bacteria.
