“…MTT tests and SEM observations showed a decrease in colonization of the different strains on the heparinized polyurethane surfaces, confi rming that preadsorbed heparin plays a role in mediating biomaterial surface/bacterial cells interactions. The cellular behaviors of human umbilical vascular endothelial cells, such as attachment, growth and proliferation, were signifi cantly increased onto the PU fi lms surface modifi ed by microwaveinduced argon plasma treatment (Lim et al, 2008).…”

“…It has been shown that in plasma inactivation treatment the major role is played by the neutral species [3,[5][6][7][8][9], which has led the attention to be focused on the post-discharge region, where active radicals and excited species rather than charged particles are present [10][11][12]. The post-discharge, compared with the discharge zone, has the great advantage of fulfilling the two conditions of much lower gas temperature and absence of charged species since these could damage the material to be sterilized.…”

The distribution of active species in remote oxygen and nitrogen plasma and the germicidal effect (GE) of Staphylococcus aureus on the surface of medical poly(tetrafluoroethylene), polyvinyl chloride and polyethylene terephthalate films, which had been widely used in medical devices, were studied. The results showed that the concentration of electrons and ions decreased rapidly with increasing the distance from the center of induction coil, which approximated to 0 at 40 cm, whereas the concentration of both oxygen and nitrogen radicals reduced slowly, which decreased 20% within 40 cm. Fast etching action on cell membrane by electrons, ions and radicals are primary reasons of oxygen and nitrogen plasma inactivation, which leads to the cellular contents effuse and engender bacteria death, however, the GE of UV radiation in remote plasma is feebleness comparatively. The GE also depends on the oxidation of gas for discharge and the surface characters of material.

“…Plasma surface modification is commonly used to increase the surface oxygen concentration and interfacial adhesion. It is known that native and plasma-modified polymers with oxygen-containing surface groups generally support protein and cell adhesion [13]. The studies in the literature have determined that cell proliferation and expression can be regulated by the chemical properties of the matrix [39].…”

“…Although different plasma modification techniques were reported to obtain functional groups on different 2D polymer films [11][12][13][14][15], there are not enough studies indicating the effects of plasma on both 2D and 3D structures. In this study, the effects of low-pressure water/O 2 plasma modification on 2D degradable PCL (poly-ε-caprolactone) membranes and 3D non-degradable NWPF (non-woven polyester fabric) discs were investigated for periodontal ligament (PDL) cell cultivation.…”

In this study, low pressure water/O 2 plasma treatment was performed in order to obtain COOH functionalities on the surface of poly-ε-caprolactone (PCL) membranes as well as non-woven polyester fabric (NWPF) discs. The plasma treatments were performed in a cylindrical, capacitively coupled RF-plasma-reactor and then following steps were performed: in situ (oxalyl chloride vapors) gas/solid reaction to convert -OH functionalities into -COCl groups; and hydrolysis under open laboratory conditions using air moisture for final-COOH functionalities. COOH and OH functionalities on modified surfaces were detected quantitatively by using fluorescent labeling technique and an UVX 300G sensor. Electron spectroscopy for chemical analysis (ESCA) was used to evaluate the relative surface atomic compositions and the carbon and oxygen linkages located in non-equivalent atomic positions of untreated and modified surfaces. Atomic force microscope (AFM) analysis showed that nanoscale features of the PCL surfaces are dramatically changed during the surface treatments. Scanning electron microscopy (SEM) results indicated the changes in the relatively smooth appearance of the untreated NWPF discs after the plasma treatment. Periodontal ligament (PDL) fibroblasts were used in cell culture studies. Cell culture results showed that plasma treated PCL membranes and NWPF discs were favorable for the PDL cell spreading, growth and viability due to the presence of functional groups and/or nanotopographies on their surfaces.
