Electrode Coatings Based on Chitosan Scaffolds

Analytical Chemistry, 2000
Thin films of a biopolymer chitosan (CHIT) were cast on glassy carbon electrodes, modified by grafting Lucifer Yellow VS dye (LYVS) onto chitosan chains, and cross-linked with glutaric dialdehyde (GDI). The ion-transport and ion-exchange properties of such polymeric structures (CHIT, CHIT-LYVS, CHIT-LYVS-GDI) were studied using cyclic voltammetry ...

Lead electrocapture on hydroxyapatite coated electrodes

Chemosphere, 2005
Hydroxyapatite coated electrodes were made by a hydrolysis reaction involving silanes and hydroxyapatite particles on stainless steel. Aqueous lead ions were captured on the coatings with or without electromigration. Results depend on coating thickness, supporting electrolyte and the presence of the electric field.

Impedance spectra of polypyrrole coated platinum electrodes

2013 35th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2013
Polypyrrole (PPy) coated electrodes may provide new solutions to increase the charge injection capacity and biocompatibility of metal electrodes in e.g., neural stimulus applications. In this study, electrical impedance spectra of PPy coated platinum (Pt) electrodes having three different coating thicknesses were measured and modeled.

Conducting Polymers as Electrode Coatings for Neuronal Multi-electrode Arrays

Trends in Biotechnology, 2017
In this new era of bioelectronics, refining transduction pathways between biological systems and electrodes is becoming an increasingly important task. This forum provides insights on how conducting polymer electrode coatings provide more sensitive and compatible systems for recording between the nervous system and electronics.

Interfacial Properties of Copper‐coated Graphite Electrodes: Coating Thickness Dependence

Fuel Cells, 2009
AbstractCopper‐coated graphite electrodes have been prepared by physical vapour deposition (PVD) and characterised as anodes for Li‐ion batteries. The interfacial properties of the electrodes coated with copper layers of different thicknesses have been studied using impedance spectroscopy and compared with those of unmodified electrodes.

Laminin coated diamond electrodes for neural stimulation

Materials Science and Engineering: C, 2021
The performance of many implantable neural stimulation devices is degraded due to the loss of neurons around the electrodes by the body's natural biological responses to a foreign material. Coating of electrodes with biomolecules such as extracellular matrix proteins is one potential route to suppress the adverse responses that lead to loss of implant ...

Pyrolytically coated carbon cloth electrodes

Journal of Applied Electrochemistry, 1979
The performance of carbon cloth electrodes with a pyrolytic graphite coating deposited on their surface is reported. Cyclic voltammograms recorded with treated and untreated cloth, in the −0·9 to +0·9 V (versus Ag/AgCl) potential range, are compared.

Nanostructured PEDOT Coatings for Electrode–Neuron Integration

ACS Applied Bio Materials, 2021
Neural electrodes have been developed for the diagnosis and treatment of stroke, sensory deficits, and neurological disorders based on the electrical stimulation of nerve tissue and recording of neural electrical activity. A low interface impedance and large active surface area for charge transfer and intimate contact between neurons and the electrode ...

Membrane-type coatings on electrodes

Electrochimica Acta, 1988
Abstract The behaviour of electrodes coated with electronically insulating but permeable films is reviewed. The emphasis is on films with ion-exchange properties. The structure of the metal—film interphase, the film—solution interphase with its membrane equilibria, and transport processes across the films including the role of migration are discussed.

Electrodes with Activated Pyropolymer Coatings

Journal of The Electrochemical Society, 1986
The development of electrode coatings based on conducting activated pyropolymers has been actively persued at ELTECH Electrosearch laboratory since 1978. The activated pyropolymer coating is obtained by controlled thermal treatment, starting from solutions of pyropolymer precursors such as polyacrylonitrile (PAN) and catalysts precursors such as noble ...
