Abstract

Adhesion and alignment of primary human gingival fibroblast to Petri dishes were controlled by proper modification of the surface chemistry of the solid substrate. In particular, air plasma (glow-discharge) treatment, coupled to a masking technique, was used to pattern cell-adhesive areas on a cell-adhesion-resistant alginate coated surface. Fibroblasts were successfully confined to the air plasma-treated areas, which show a much greater growth rate and cell density as compared to the original alginate coated surface. Beside the implications for the study of the mechanisms of bio-adhesion at hydrophilic surfaces, these systems can be of interest for a number of applications in dental surgery and materials.
