A wearable sweat biosensing device is demonstrated that stimulates and continuously measures ethanol concentrations at 25 s intervals, which then correlated with blood during a >3 hour testing phase. The involves baseline condition (no ethanol) followed by rapid rise of (oral bolus), finally, the physiological response body as return to (metabolized). Data sets include multiple in vivo validation trials careful vitro characterization electrochemical enzymatic sensor against likely...
Reported here is a new paradigm in sweat sampling and sensing, where sample volumes are dramatically reduced analyte contamination from the skin surface mitigated.
Moving to ultra-low (<100 nL) sample volumes presents numerous challenges, many of which can be resolved by implementation open nanofluidic films. These films are fabricated using a hexagonal network gold-coated microchannels capture all the following innovative advantages: (1) <100 nL cm-2; (2) zero analyte exchange and loss with film materials; (3) rapid omni-directional wicking transport >500 min-1 per square film; (4) ultra-simple roll-to-roll fabrication; (5) stable bio-compatible...
Abstract Reported here are laminated membrane electrodes, an improved design and more advantageous method of fabrication for previously reported thin layer cell electrode systems developed on track‐etch membranes. The approach potentially further improves flow resistance by dramatically reducing the surface area to volume ratio, but also produces a cohesive device that can be readily applied broad range applications. In addition, this new was implemented in scalable, commercial process...
