Wearable sensors enable the noninvasive continuous analysis of biofluid, which is great importance for healthcare monitoring. In this work, a wearable sensor was seamlessly integrated with microfluidic chip prepared by three-dimensional printing technology and multiplexed metabolite electrolytes in human sweat. The could rapid sampling sweat, avoids sweat evaporation contamination. Using Zn metal–organic framework as sacrificial template, hexagonal rod-shaped porous carbon nanorod (PCN) high porosity, large specific surface area, excellent conductivity synthesized exhibited robust electrocatalytic ability uric acid (UA) oxidation. Therefore, PCN-based showed sensitivity good selectivity UA wide linear range 10–200 μM low detection limit 4.13 μM. Meanwhile, potentiometry-based ion-selective electrode constructed pH K+, respectively, sensitivity, selectivity, reproducibility, stability. addition, testing under different bending states demonstrated that mechanical deformation had little effect on electrochemical performance sensors. Furthermore, we evaluated utility real-time UA, pH, K+ during aerobic exercise, amount consumed purine-rich foods levels urine further investigated. relationship between obtained. Overall, enables multiple electrolyte biofluids, suggesting its potential application personalized disease prevention.

Sweat is considered the most promising candidate to replace conventional blood samples for noninvasive sensing. There are many tools and optical electrochemical methods that can be used detecting sweat biomarkers. Electrochemical known their simplicity cost-effectiveness. However, they need optimized in terms of selectivity catalytic activity. Therefore, electrode modifiers such as nanostructures metal-organic frameworks (MOFs) or combinations them were examined boosting performance sensors. The MOF structures prepared by hydrothermal/solvothermal, sonochemical, microwave synthesis, mechanochemical, methods.

Due to the intense demand for low-cost, environmentally friendly, and stable uric acid (UA) detection methods, a novel biosensing nanosystem made with marine diatom was studied. Reduced by live (Thalassiosira pseudonana), metallic nanoparticles (CuX) were hybridized heteronanostructure (Diatom frustule, DF), showing peroxidase activity 2.66-fold over horseradish (HRP). To immobilize enzyme directionally increasing loading amounts, silaffin peptides (R5 T8) designed tagging urate oxidase (UoX). The on DF of tagged UoX 1.76-fold (R5) 1.54-fold (T8) that untagged UoX. immobilized UoX-R5 5.29–11.76-fold more than free at various pH levels (5–10) temperatures (20–60 °C).
