Arsenic species interactions with a porous carbon electrode as determined with an electrochemical quartz crystal microbalance.
The interactions of arsenic species with platinum and porous carbon electrodes were investigated with an electrochemical quartz crystal microbalance (EQCM) and cyclic voltammetry in alkaline solutions. It is shown that the redox reactions in arsenic-containing solutions, due to arsenic reduction/deposition, oxidation/desorption, and electrocatalyzed oxidation by Pt can be readily distinguished ...
متن کاملDesign and Characterization of a Rotating Electrochemical Quartz-Crystal-Microbalance Electrode
A novel design for a rotating electrochemical quartz-crystal microbalance (rEQCM) which includes easily and reproducibly exchangeable quartz-crystal holders is described. The rEQCM allows for well-controlled mass-transport conditions at the working electrode on a 10 MHz quartz crystal. Together with the flexibility of the proposed design, this makes it useful for a wide range of applications in...
متن کاملProbing protein adsorption onto mercaptoundecanoic acid stabilized gold nanoparticles and surfaces by quartz crystal microbalance and zeta-potential measurements.
The adsorption characteristics of three proteins [bovine serum albumin (BSA), myoglobin (Mb), and cytochrome c (CytC)] onto self-assembled monolayers of mercaptoundecanoic acid (MUA) on both gold nanoparticles (AuNP) and gold surfaces (Au) are described. The combination of quartz crystal microbalance measurements with dissipation (QCM-D) and pH titrations of the zeta-potential provide informati...
متن کاملHighly sensitive biomolecule detection on a quartz crystal microbalance using gold nanoparticles as signal amplification probes.
We report here a novel strategy for the high-sensitive detection of target biomolecules with very low concentrations on a quartz crystal microbalance (QCM) device using gold nanoparticles as signal enhancement probes. By employing a streptavidin-biotin interaction as a model system, we could prepare biotin-conjugated gold nanoparticles maintaining good dispersion and long-term stability by cont...
متن کاملA simultaneous electrochemical impedance and quartz crystal microbalance study on antihuman immunoglobulin G adsorption and human immunoglobulin G reaction.
The quartz crystal microbalance (QCM), in combination with electrochemical impedance spectroscopy (EIS), has been utilized to monitor in situ antihuman IgG (hIgG) adsorption on bare poly(o-phenylenediamine) (PPD)- and 1-dodecanethiol (C12SH)-modified Au electrodes and succeeding human IgG reaction, respectively. The resonant frequency (f) and the motional resistance (R(1)) of the piezoelectric ...
