Journal ArticleDOI
Plasma-Based Surface Modification of Polystyrene Microtiter Plates for Covalent Immobilization of Biomolecules
Stella H. North,Evgeniya H. Lock,Candace J. Cooper,J.B. Franek,Chris R. Taitt,Scott G. Walton +5 more
TL;DR: It is demonstrated that the plasma treatment followed by silane derivatization supports direct, covalent immobilization of biomolecules on microtiter plates and thus overcomes challenging issues typically associated with simple physisorption.
Journal ArticleDOI
Power supply and impedance matching to drive technological radio-frequency plasmas with customized voltage waveforms
J.B. Franek,Steven Brandt,Birk Berger,Martin Liese,Matthias Barthel,E Schüngel,Julian Schulze +6 more
TL;DR: A comparison with the reference case of an electrically asymmetric dual-frequency discharge reveals that the control range of the mean ion energy can be significantly enlarged by using more than two consecutive harmonics.
Journal ArticleDOI
Effect of Physicochemical Anomalies of Soda-Lime Silicate Slides on Biomolecule Immobilization
TL;DR: It is shown that recent changes in the chemical and physical properties of commercial soda-lime slides affect the ability of these slides to be covalently modified, and a correlation between magnesium content, surface roughness, and bioimmobilization efficiency is revealed.
Journal ArticleDOI
Determination of Ar metastable atom densities in Ar and Ar/H 2 inductively coupled low-temperature plasmas
Nick Fox-Lyon,Andrew J. Knoll,J.B. Franek,Vladimir Demidov,Vladimir Demidov,Valery Godyak,Mark Koepke,Gottlieb S. Oehrlein +7 more
TL;DR: In this article, a model combining electrical probe measurements of electron density (Ne) and temperature (Te), with analysis of spectrally resolved Ar plasma optical emission based on 3p − 1s optical emission ratios of the 419.8 -nm line to the 420.1-nm line was presented.
Journal ArticleDOI
Experimental investigations of electron heating dynamics and ion energy distributions in capacitive discharges driven by customized voltage waveforms
Birk Berger,Birk Berger,Steven Brandt,J.B. Franek,E Schüngel,Mark Koepke,Thomas Mussenbrock,Julian Schulze +7 more
TL;DR: In this article, phase-resolved optical emission spectroscopy (PROES) was used to study the spatio-temporal electron heating dynamics in an argon discharge driven by up to three consecutive harmonics of 13.56 MHz with individually adjustable harmonics' amplitudes and phases.
