5. Illustrative results on the effectiveness of polymer-silver composite film

5.1 Yeast adhesion to plasma-modified surface: comparison with native surface

In the example presented here, the operating conditions chosen for plasma treatment (argon pressure = 40 mTorr, HMDSO flow rate = 0.1 sccm, P _HMDSO = 2.5 mTorr, I _Ag / I _Ar = 0.20) resulted in a composite film comprising 25% silver. The corresponding yeast detachment profile is shown in figure 10 . Control" profiles, obtained with baker's yeast previously adhered to virgin stainless steel and coated...
