“…Such sensor could become the basis of a POC device for chronic wound care. Several sensors to assess wound healing progression have been developed, targeting infection, pH, oxygen, uric acid, hemoglobin, and broad-spectrum proteases (Dargaville et al, 2013;Edwards et al, 2013;Sharp, 2013;Krismastuti et al, 2014Krismastuti et al, , 2015aKrismastuti et al, , 2017Ochoa et al, 2014;Salvo et al, 2015;Jankowska et al, 2017;RoyChoudhury et al, 2018). These sensors have not reached yet the stage of deployment in the clinic due to the challenges involved, such as the complex wound environment with hundreds of proteins present in a wide pH range.…”
