Journal ArticleDOI
Electrode passivation caused by polymerization of different phenolic compounds
TL;DR: An electrochemical quartz crystal microbalance was used to investigate the formation of polymeric products resulting from electrooxidation in aqueous solutions of phenolic compounds on the surface of Au and Pt electrodes as discussed by the authors.
Journal ArticleDOI
Diffusion in supported lipid bilayers: influence of substrate and preparation technique on the internal dynamics.
TL;DR: Over micrometer length scales, the validity of a purely Brownian diffusive law both in the gel and the fluid phases of the lipids is demonstrated.
Journal ArticleDOI
Enzyme-mediated amperometric biosensors prepared with the Layer-by-Layer (LbL) adsorption technique.
TL;DR: The stability of the biosensors was checked by observing an almost constant sensitivity for a period of approximately 20 days, thus indicating a stable adsorption of GOD.

TL;DR: A suite of software tools, referred to as PEx-Sensors, through which projection techniques are used to analyze electrical impedance spectroscopy data in electronic tongues and related sensors, showing that non-linear projection techniques such as Sammon's Mapping or IDMAP provide higher distinction ability than linear methods for sensor arrays containing units capable of molecular recognition.

TL;DR: In this paper, molecular-level interactions are found to bind iron tetrasulfonated phthalocyanine (FeTsPc) and polyelectrolyte poly(allylamine hydrochloride) (PAH) in electroactive layer-by-layer (LBL) films.
