Abstract

In this study; the foley catheters were modified by plasma polymerization technique and coated with alginate gels. Thismodification processes were applied to prevent bacterial adhesion onto the foley catheter surfaces. Here the mosteffective parameters were evaluated as the plasma polymerization system power and plasma exposure time for theeffective catheter surface modification. The obtained results showed that the plasma power affected hidrophilicity ofthe surface and wettability of the foley catheters was increased. The plasma exposure time increased the amount ofEDA deposition over the catheter surfaces and then caused more hydrophilicity for the foley catheter surfaces also.In this study, the bacterial strain ofE. Coli had a hydrophobic nature and therefore the increase in hydrophilicity ofthe surface of foley catheters decreased the adhesion risk for theE. Coli onto the catheter surfaces. As the numericalvalues of the obtained data; while the amount of bacterial colony formation unit was at 108 level initially, it wasdecreased down to 104-103level by changing the surface hydrophilicities as expected
