Electrochemical bioassays based on oxidase reactions are frequently used in biological sciences and medical industries. However, the enzymatic reaction kinetics are severely restricted by the poor solubility and slow diffusion rate of oxygen in conventional solid‒liquid diphase reaction systems, which inevitably compromises the detection accuracy, linearity, and reliability of the oxidase‐based bioassay...
Due to their marvelous electrical and optical properties, perovskite nanocrystals have reached remarkable landmarks in solar cells, light‐emitting diodes, and photodetectors. However, the intrinsic instability of ionic perovskites, which would undergo an undesirable phase transition and decompose rapidly in ambient humidity, limits their long‐term practical deployment. To address this challenge, halogenated...
Recently, flexible pressure sensors (FPSs) have attracted intensive attention owing to their ability to mimic and function as electronic skin. Some sensors are exploited with a biological structure dielectric layer for high sensitivity and detection. However, traditional sensors with bionic structures usually suffer from a limited range for high‐pressure scenes due to their high sensitivity and high...
Mesocarbon microbeads (MCMB) are highly desirable as anode materials for rechargeable potassium ion batteries (PIBs) due to their commercially availability, high stability and low‐cost. However, their charge storage and interfacial mechanisms are still unclear. In this work, the intercalation mechanisms and the solid‐electrolyte‐interphase (SEI) formation of the MCMB in four different electrolytes...
Noninvasive bioassays based on the principle of a hydrogen peroxide (H2O2) cathodic reaction are highly desirable for low concentration analyte detection within biofluids since the reaction is immune to interference from oxidizable species. However, the inability to selectively reduce H2O2 over O2 for commonly used stable catalysts (carbon or noble metals) is one of the key factors limiting their...
