Abstract

) and human keratinocytes (HaCaT) with the film surface. Consequently, after activation with ultrasound (1 MHz), the surface very effectively transferred the signal to the adhered cells, which resulted in fast and effective antimicrobial activity. Moreover, for adhered HaCaT cells, stimulation promoted proliferation, cell mobility, intercellular connections and cytoskeleton formation. In combination, these two types of interactions are very important for promoting skin regeneration and wound healing.
