摘要: Dehydration and over-hydration are a serious health concern in endurance sport activities, especially tropical climates. Current methods for detection inconvenient not widely applied. Point-of-care hydration monitoring during event is an ideal preventative therapy, as it allows personalize real-time feedback towards preventing related injuries. Gold nanoparticles allow colorimetric detection, whose color changes due to colloidal stability. The red-shift the plasmonic band induces change from red purple upon aggregation that can be observed by naked eye, which gives promising applications point-of-care therapies. We developed gold nanoparticle-based sensor rapid of dehydration ‘proof-of-concept’ artificial sweat ion concentrations. was designed distinguish between through easily changes. In addition, exhibited fast response time within minutes. tool over-hydration.
