Flexible and washable self-powered biosensors based on textile bioelectrodes for sensing glucose in sweat
This study fabricated a flexible and washable self-powered biosensor—based on cellulose textiles—for sensing glucose in sweat. The sensor is integrated with T-shirts for practical use. The cellulose fiber was modified with carbon nanotubes and reduced oxide graphene to decrease its electron transfer resistance and ohmic resistance. Due to their low resistance, the bioelectrodes display high electrocatalytic efficiency of glucose oxidation and oxygen reduction. The biosensors are assembled by packaging the bioanodes and gel electrolytes together. The assembled biosensors have a low limit of detection (6.7 µM) and a wide linear range (0.02–0.5 mM). The great sensing performances are strongly associated with the location of bioanodes and biocathodes. The outer biocathode protects the central bioanode that comes from oxygen and ensures the structural integrity of the device during bending cycles. It also reduces the damage caused by the washing. The biosensor also exhibited selectivity, repeatability, and great stability in different pHs and during long-term storage. Finally, the average recoveries in real sweat are 104.9 to 106.0%. Thus, the flexible and washable self-powered biosensors have great potential for diabetes diagnosis at an early stage by sensing glucose in sweat.
期刊介绍：
The Journal of Solid State Electrochemistry is devoted to all aspects of solid-state chemistry and solid-state physics in electrochemistry.
The Journal of Solid State Electrochemistry publishes papers on all aspects of electrochemistry of solid compounds, including experimental and theoretical, basic and applied work. It equally publishes papers on the thermodynamics and kinetics of electrochemical reactions if at least one actively participating phase is solid. Also of interest are articles on the transport of ions and electrons in solids whenever these processes are relevant to electrochemical reactions and on the use of solid-state electrochemical reactions in the analysis of solids and their surfaces.
The journal covers solid-state electrochemistry and focusses on the following fields: mechanisms of solid-state electrochemical reactions, semiconductor electrochemistry, electrochemical batteries, accumulators and fuel cells, electrochemical mineral leaching, galvanic metal plating, electrochemical potential memory devices, solid-state electrochemical sensors, ion and electron transport in solid materials and polymers, electrocatalysis, photoelectrochemistry, corrosion of solid materials, solid-state electroanalysis, electrochemical machining of materials, electrochromism and electrochromic devices, new electrochemical solid-state synthesis.
The Journal of Solid State Electrochemistry makes the professional in research and industry aware of this swift progress and its importance for future developments and success in the above-mentioned fields.
