Characterization of the swelling of acrylamidophenylboronic acid-acrylamide hydrogels upon interaction with glucose by faradaic impedance spectroscopy, chronopotentiometry, quartz-crystal microbalance (QCM), and surface plasmon resonance (SPR) experiments

Article Abstract:

An m-acrylamidophenylboronic acid acrylamide copolymer is assembled by electro polymerization on Au-surfaces. The study has applied a battery of physical methods to characterize the swelling and shrinking of a glucose-responsive copolymer and has revealed different methods to characterize the structure of the hydrogels and the kinetics of glucose-induced swelling and polymer shrinking processes.

The use of impedance spectroscopy for the characterization of protein-modified ISFET devices: application of the method for the analysis of biorecognition processes

Article Abstract:

A novel method that is based on impedance measurements to characterize protein architectures assembled on the gate interface of an ISFET device is presented. The method is used to sense the dinitrophenyl antibody by following the formation of the antigen-antibody complex on the gate surface.

Nickel electrodeposition on a gold polycrystalline foil: A combined voltammetric and photoelectron spectroscopy study

Article Abstract:

In this discussion a combined photoelectron spectroscopy and electrochemical study of nickel deposition on gold is presented. The results show that Ni depositions is qualitatively and quantitatively controlled by the applied potential.
