“…Oxygen plasma turned out to be very efficient in reducing the surface energy of polymers, as has been reported by Öktem et al [28] and Mittal [29]. Oxygen or noble gases must be used during plasma treatment in order to stabilize free radicals formed on the surface being treated [30].…”

“…The density of amino groups per unit area was reported elsewhere (Mutlu et al 1991). Therefore, the presence of amino groups incorporated onto the PlzP-EDA surface (Mutlu et al 1999(Mutlu et al , 2008Biederman et al 2001;Saber et al 2002) form a steric barrier with very high density, repelling microorganisms approaching the surface, among the other precursors were studied in this research. The multi-component crosslinked EDA-based polymer coatings contributed to a significant reduction in adhesion of E. sakazakii when compared to bare 316 stainless steel.…”

In this study, the prevention of the attachment of test microorganism Enterobacter sakazakii onto stainless steel (SS 316) surfaces by radio frequency (RF) plasma polymerization (PlzP) technique using several hydrophilic monomers as precursors was reported. Different plasma conditions (RF discharge power of 20-80 W with exposure time of 10 min) were employed during the modifications. PlzP-modified surfaces were characterized in detail by static contact angle measurements in order to state the change of surface hydrophilicity. The surface topology of unmodified and PlzP [ethylenediamine (EDA)]-modified SS 316 plates was characterized by atomic force microscopy. The attachment of the model microorganism on the SS 316 surface modified by plasma using EDA at 45 W and 10 min was reduced by 99.74% in comparison to the unmodified control surface. For equilibrium adsorption behavior, Freundlich and Langmuir models were attempted and model parameters for Freundlich (K F and 1/n) and for Langmuir (a and b) were obtained. The values of the K F and 1/n were 5.6 and 0.58 and 0.9 and 0.39, respectively; the values of a and b were 25×10 4 and 1.82×10 −8 and 0.3×10 4 and 7.96×10 -8 , for bare and PlzP-EDA-modified SS 316 surfaces, respectively. As a result, PlzP technique was found to be an alternative simple method to decrease the microbial attachment and create bacterial anti-fouling surfaces.

“…The magnetic force was useful to enhance the response of the sensor. Many other studies were developed using the QMC technique to confirm the deposition of biological molecules on self-assembled superstructures and immunosensor assay (Shen et al, 2001;Calvo et al, 2004;Tlili et al, 2004;Mutlu et al, 2008;Boujday et al, 2009). A deep discussion on the use of QMC technique on the step-by-step immunosensor characterization and on immunosensor assay can be found in another specific chapter in this book.…”
