Here, we report the fabrication of a novel ε-caprolactam-silica (ε-SiO2) network and assessed its biocompatibility and ability to improve the antimicrobial activity of kanamycin. The results of the quantitative antimicrobial assay demonstrate that the obtained ε-SiO2 network has efficiently improved
