Biocompatibility of Carbon Layer on Polymer

Abstract

Polymers with modified surface structure are useful for medicine applications. This study is focused on the surface properties of polymers with carbon layers and their biocompatibility. For experiments was used polyethyleneterephtalate (PET). We used magnetron sputtering for producing of the carbon layers. Raman spectroscopy, goniometry, AFM – microscopy, X-ray diffraction and infrared spectroscopy were used in our experiments to describe the physicochemical properties of modified polymers. Biocompatibility of structure polymer-carbon layers was studied with method in vitro. We investigated adhesion of mouse 3T3-fibroblasts. The carbon layers have positive influence on biocompatibility.

The Properties and Application of Carbon Nanostructures

“…8) [38]. The number of adhering cells increases with increasing deposition time for deposition times up to 30 min (Fig.…”

“…Sputtered or evaporated [37] carbon structures can create nanostructures of different electrical or morphological properties. The opportunities for systematic investigation of nanolayers structures [38][39][40][41][42] are very promising for new application both in electronics or nanoengineering and biomedicine.…”
