Monitoring of the evolution of human chronic wounds using a ninhydrin-based sensory polymer and a smartphone

The healing processes in cutaneous wounds, i.e., chronic represent a health problem affecting 1–2 % of the population. evaluation these wounds is mainly based on subjective parameters, although there medical consensus protease activity as best marker for disorders. Here we show correlation amino acid concentration and with their evolution, development test kit to straightforward determining this evolution. Our colorimetric sensory polymer film that change its colour upon contacting acids. allows quantification overall by simply analysing definition parameters obtained from photograph taken smartphone. We analysed human 34 patients mathematically demonstrate concentration, related activity, evolution wound’s diagnoses. This can help diagnosis usually evaluated treated along time different physicians, or even teams, providing an analytical tool not subjected evaluation.
