“…The thickness of each monomer layer was controlled by plasma deposition time. [22] Characterization of the Bipolar Films Bipolar films composed of only a thin Aac film with thickness of 2 nm and a thin Aam film with thickness of 2 nm were analyzed by X-ray photoelectron spectroscopy (XPS, XSAM800, Kratos Ltd, UK) to determine the surface elemental compositions. The instrument was equipped with a monochromatic Mg K a (1 253.6 eV) X-ray source operated at 12 kV at a pressure of 5-7 Â 10 À9 mbar.…”

A facile approach to a highly bio-active interface material is reported. XPS reveals that polar entities exist at the interface between PPAam and PPAac nanolayers. They induce strong dipolar orientation polarizability and cause the redistribution of charges, which results in a remarkable increase of polar surface energy and hydrophilicity of the multistack bipolar films. In particular bipolar films with amine groups on their outermost surface show strongly enhanced cellular mobility. The attachment, adhesion, proliferation, migration, and coverage of ECs are significantly enhanced on such films. They are therefore promising as vascular implant materials, and could have applications as coating materials for tissue engineering.

“…Position settings of eight QCMs on the lower electrode are denoted as shown in Fig. 1(b) in ref [21]. Prior to plasma polymerization, both sides of eight QCMs were treated by plasma sputtering for 60 s under 100 W of RF power and 100 Pa of He pressure.…”

Styrene, allylamine, and acrylic acid were polymerized on a quartz crystal microbalance (QCM) by plasma polymerization technique under 100 W, 100 P, and a settled period of each. Coating amounts of plasma polymerized films (pp-films) were determined by QCM technique. Adsorption amounts of anti-C-reactive protein monoclonal IgG antibody (CRP antibody) and its F(ab')2 fragment of IgG antibody (CRP-F(ab')2 antibody) on three plasma-polymerized films and on a gold QCM surface as a reference were also determined by QCM technique. Immunoreaction amounts between antigen (CRP) and antibodies adsorbed QCM on pp-films were determined by QCM. Adsorption amount of CRP antibodies or CRP-F(ab' )2 antibodies for pp-films and gold were almost similar levels in the range of 50 to 100 Hz per area. Immunoreaction amounts of CRP depended on the combination of pp-films and antibodies. The largest dose-responses of Immunoreaction were obtained for pp-acrylic acid for CRP antibodies, and pp-allylamine for CRP-F(ab')2 antibodies. These results imply that molecular orientation of antibodies adsorbed on pp-films may be performed in different manners.

“…This method allows for solvent free deposition of a wide range of thin polymer films on the surface of most sensors including cantilever and quartz crystal microbalance (QCM) based sensors. 6 Plasma polymerization also offers excellent control over film thickness since it is directly proportional to polymerization time as confirmed by Kurosawa et al 7 A wide selection of monomers with many different functional groups can be used for plasma polymerization making it a very versatile technique. The choice of monomer naturally depends on the target analytes to be detected.…”

Data-driven modeling of nano-nose gas sensor arrays

et al. 2010

We present a data-driven approach to classification of Quartz Crystal Microbalance (QCM) sensor data. The sensor is a nano-nose gas sensor that detects concentrations of analytes down to ppm levels using plasma polymorized coatings. Each sensor experiment takes approximately one hour hence the number of available training data is limited. We suggest a data-driven classification model which work from few examples. The paper compares a number of data-driven classification and quantification schemes able to detect the gas and the concentration level. The data-driven approaches are based on state-of-the-art machine learning methods and the Bayesian learning paradigm.
