“…Upon infection, bacteria seek to increase the wound pH to create an environment that is more accommodating to their growth. [ 28,29 ] It has been proposed that this increase in pH could be a diagnostic handle through which to identify the onset of infection [ 30 ] and there is an increasing effort to develop disposable pH sensors that could be applied to wound monitoring.

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.

“…Given the importance of pH to a range of biochemical processes, including the activity of proteolytic enzymes, the ability to monitor pH and modulate it (through treatments and dressings) could be advantageous. New technologies are emerging to enable monitoring of pH in wounds, based upon electrochemical methods using potentiometric and voltammetric methodologies [9][10][11], inductance-based pH responsive hydrogels [12], optical fiber based sensors [13], and luminescence approaches through sensor films [14]. Investigators have also tried to elucidate whether there is a spatial disparity to pH.…”

“…These are typically based on dyes [4,5] or on inductive transducers [6] incorporated into wound dressings. For example, Trupp et al have synthesized a series of hydroxyl-substituted azobenzene derivatives as indicator dyes for optically monitoring pH between 6 and 10 [4].…”

Chronic wounds do not heal within 3 months, and during the lengthy healing process, the wound is invariably exposed to bacteria, which can colonize the wound bed and form biofilms. This alters the wound metabolism and brings about a change of pH. In this work, porous silicon photonic films were coated with the pH-responsive polymer poly(2-diethylaminoethyl acrylate). We demonstrated that the pH-responsive polymer deposited on the surface of the photonic film acts as a barrier to prevent water from penetrating inside the porous matrix at neutral pH. Moreover, the device demonstrated optical pH sensing capability visible by the unaided eye.
