A novel nanocomposite scaffold based on poly(vinyl alcohol) (PVA) and multiwalled carbon nanotubes (MWNT) were synthesized and characterized regarding to morphological, physical, and mechanical properties and also the preliminary biocompatibility was assessed by MTT assay. Additionally, the concept of developing hybrid systems was tested by bioconjugating functionalized MWNT to glucose oxidase and dispersed in the PVA matrix. The nanocomposites have presented mechanical properties, degree of swelling, and cytocompatibility comparable to the skin tissues. Moreover, the bionanocomposite with enzyme showed bioactivity toward injecting glucose with simultaneous antimicrobial behavior against bacterial pathogens due to the generation hydrogen peroxide.
