Wound Diagnostics: Deploying Electroanalytical Strategies for Point of Care Sensors and Smart Dressings.

Chronic wounds are highly heterogeneous with the complications of tissue remodelling and issues such as infection generating a multitude of molecular and cellular species. It could be anticipated that were information regarding the dynamics of key wound biomarkers available to the clinician, more informed decisions could be implemented to encourage the reinstatement of normal healing processes. There are few diagnostic options available at the time of consultation and the aim of this review has been to assess the capability of electrochemical sensing strategies to provide detailed point of care information on the wound condition. Advances in functional materials and the greater accessibility of disposable printed systems are beginning to provide a solid foundation through which low cost devices could be realised and whose deployment could lead to more informed decision making and positive outcomes.
