“…The carbon fragments could also be embedded within the wound as tissue remodeling commences leading to a need to debride the wound and further impeding the healing processes. An alternative approach to counter this issue has been investigated through the use of carbon composite polymers based on polyethylene [ 17 ] , [ 18 ] , [ 19 ] , [ 20 ] , and [16 ] respectively; the images presented here are original.…”

“…More importantly, they can be directly integrated within a conventional wound dressing. It was envisaged that the carbon component would provide the framework for electrochemical transduction enabling quantitative information on key biomarkers associated with wound healing to be extracted through an appropriate electronic monitor, [ 18 ] worn either by the patient or connected at the time of consultation. This would be a more viable solution given the inherent mechanical fl exibility of the composite fi lm -a prerequisite given the high degree of morphological variability encountered with diabetic ulcers.…”

“…The electroanalytical performance of these fi lms has been shown to accurately measure pH, having been tested in simulated and whole blood samples. [ 18,19 ] Thus far, urate has been used as an indicator of pH yet it has been established in recent years that its quantifi cation is of considerable interest as Fernandez et al (2012) have shown that its concentration is elevated as a consequence of tissue remodeling within the wound. The cellular trauma and associated healing processes result in the release of adenosine triphosphate (ATP) into the extracellular wound matrix, which is subsequently metabolized into uric acid.…”

The pH of wound fluid has long been recognized as an important diagnostic for assessing wound condition, but as yet there are few technological options available to the clinician. The availability of sensors that can measure wound pH, either in the clinic or at home could significantly improve clinical outcome - particularly in the early identification of complications such as infection. New material designs and electrochemical research strategies that are being targeted at wound diagnostics are identified and a critical overview of emerging research that could be pivotal in setting the direction for future devices is provided.

“…Again, substantial advances in the design of inexpensive electrode platforms has been achieved in recent years and can be typified by woven carbon fibre [51], conductive polymer films [52][53][54] and screen printed electrodes [55][56][57] -all of which could be fashioned into a mesh and which would bring a degree of commercial viability. One question that arises, however, is: where would the mesh be positioned?…”

Flexible Nanoporous Gold Electrodes for Electroanalysis in Complex Matrices

Flexible, three‐dimensional nanoporous gold (NPG) electrodes were fabricated on polydimethylsiloxane (PDMS) surfaces without any functionalization, and their electrochemical properties examined in the absence and presence of common biofouling agents using cyclic voltammetry and redox potentiometry. In this work, potassium ferricyanide and fibrinogen were used as a model redox probe and denaturing agent, respectively, to demonstrate that flexible NPG electrodes behave ideally and can make electrochemical measurements in biofouling solutions. Using cyclic voltammetry, the non‐faradaic capacitive current was shown to be directly proportional to the scan rate, while the redox chemistry of potassium ferricyanide in the presence and absence of fibrinogen demonstrated reversible voltammetry. Using redox potentiometry, Nernst plots for the potassium ferri‐/ferrocyanide redox system gave rise to an expected Nernstian slope of 60 mV. These flexible electrodes could be particularly beneficial in electrochemical sensing in complex environments. Proof of concept was demonstrated through the measurement of uric acid in red blood cell packets using cyclic voltammetry.
