Electrolytes play a pivotal role in regulating cardiovascular functions, hydration, and muscle activation. The current standards for monitoring electrolytes involve periodic sampling of blood measurements using laboratory techniques, which are often uncomfortable/inconvenient to the subjects add considerable expense management their underlying disease conditions. wide range skin interstitial fluids (ISFs) correlations with those plasma create exciting opportunities applications such as electrolyte circadian metabolism monitoring. However, it has been challenging monitor these ISFs. In this study, we report minimally invasive microneedle-based potentiometric sensing system multiplexed continuous Na+ K+ consists miniaturized stainless-steel hollow microneedle prevent sensor delamination set modified electrodes multiplex We demonstrate measurement artificial ISFs fast response time, excellent reversibility repeatability, adequate selectivity, negligible potential interferences upon addition physiologically relevant concentration metabolites, dietary biomarkers, nutrients. addition, maintains sensitivity after multiple insertions into chicken model. Furthermore, calibrated sensors confirm accurate physiological Finally, skin-mimicking phantom gel model experiments sensor's developed platform can be adapted other applications, including real-time nutrients, proteins.

Abstract Porous liquids (PLs), an emerging type of flowing liquid materials that combine the merits porous solids and liquids, have garnered immense attention since concept PLs was proposed in 2007. Meanwhile, witnessed growing success versatile synthesis strategies applications, especially 2017. Given lack a timely comprehensive review, developing prompt summary with understanding is undoubtedly urgent. Thus, this critical review offers progress fundamental chemistry, developmental history, synthetic strategies, applications PLs. First, chemistry history are reviewed. Then, highlighted. Additionally, crosscutting studies pure theoretical simulations daunting characterization issues analyzed. Next, state‐of‐the‐art reviewed detail. In end, perspectives regarding remaining challenges future directions for presented. It speculated could inspire scientific communities who focus on task‐specific various such as gas sorption, membrane separation, catalytic conversion, chiral thermal management electrolyte, so on.

Abstract Sweat pH monitoring is a routine indicator in wearable biotechnology. The state‐of‐the‐art sensors mostly rely on organic materials but face the risk of biological toxicity. WO 3 typical H + ‐sensitive inorganic material with chemical stability, biocompatibility, and low cost sensitivity slow response. Lattice intercalation herein proposed as an efficient approach that can greatly improve selectivity ‐based sensors. Specifically, lattice promote from monoclinic phase to cubic phase, which enhances ion exchange capacity between . resistance decreases more than two orders magnitudes, improves interfacial charge transport. occupancy leads only , thus increasing recognition. intercalated x exhibits much improved sensitivity, reversibility, response time. Additionally, integrated solid reference electrode miniaturized chip for sweat monitoring. sensor good potential even at curving over 270°. On‐body measurments show high accuracy compared ex situ analyses. This work emphasizes concept proton regulate recognition contacts.
