Summary: The study investigated the dielectric, impedance, modulus, and conductivity properties of Co3O4, NiO, and Co3O4-NiO nanocomposites with varying NiO concentrations. It was found that dielectric constant, conductivity, and activation energy are influenced by temperature, frequency, and concentration. The AC conduction mechanism was analyzed based on the Correlated Barrier Hopping and Non-Overlapping Small Polaron tunneling models. The Nyquist plot and AC conductivity variation as a function of temperature provided insights into the material's electrical conduction behavior.

Summary: Establishing a platform with different nanostructured oxides is a novel idea for developing highly sensitive and selective sensing devices. The study successfully created 3D-heterostructures consisting of 1D nanowires of NiO and WO3, exhibiting selective behavior towards different gases. The improved sensing performance of the heterostructures is attributed to charge carrier transport through specific interfaces and modulation of charge carriers in the electron depletion layer of WO3 and hole accumulation layer of NiO and NiWO4.

Summary: This article introduces an artificial intelligence-enhanced metamaterial waveguide sensing platform for the analysis of aqueous mixtures in the mid-infrared spectrum. With this platform, the absorption spectra of ternary mixtures in water can be successfully distinguished and decomposed to predict concentration. Additionally, accurate classification of 64 mixing ratios and four concentrations (below the detection limit of 972 ppm) with a classification accuracy of 98.88% and 92.86% respectively, as well as concentration prediction with root-mean-squared error ranging from 0.107% to 1.436%, are achieved. This research demonstrates the potential of further extending this sensing platform to a mid-infrared spectrometer-on-chip for data analytics of multiple organic components in aqueous environments.

Summary: In this study, a lysosome-targeting buffering fluorogenic probe (Lyso-BFP) was designed and synthesized, demonstrating excellent photostability, pH specificity, and responsiveness to lysosomal acidification in living cells. The performance of Lyso-BFP in pH sensing was attributed to the inhibition of the photo-induced electron transfer process. Lyso-BFP allowed for wash-free imaging and long-term real-time monitoring of lysosome pH changes based on its off-on fluorescence behavior and buffer strategy.

Summary: In this study, a near-infrared fluorescent probe HCBG was developed for imaging of alpha-GLC. HCBG exhibited excellent selectivity and sensitivity towards alpha-GLC in complex bio-samples, and showed good cell permeability for in situ real-time imaging. Through the high-throughput screening system established by HCBG, a natural alpha-GLC inhibitor was successfully isolated and identified. This study provides a novel fluorescence visualization tool for discovering and exploring the biological functions of diabetes-related gut microbiota, and a high-throughput screening approach for alpha-GLC inhibitor.

Summary: The molecular subtype of breast cancer guides treatment and drug selection. Invasive tests can promote cancer cell metastasis, so the development of high-performance, low-cost diagnostic tools for cancer prognosis is crucial. Liquid biopsy techniques enable noninvasive, real-time, dynamic, multicomponent, quantitative, and long-term observations at the cellular, genetic, and molecular levels. A Cu-Zr metal-organic framework (MOF) nanoenzyme with monatomic Cu attachment has been synthesized and proven to have high catalytic performance. The sensor constructed using this nanoenzyme shows potential for accurate classification of breast cancer serum samples.

Summary: This study presents a method to fabricate independently functioning microneedle (MN) electrodes with narrow intervals for high precision electrochemical sensing. The optimized mixture of photocurable polymer and single-wall carbon nanotubes was used to mold single composite MNs, which were then attached to pre-patterned electrodes. Plasma etching and electropolymerization were performed to enhance the electrochemical activity, and Prussian blue and glucose oxidase were electrodeposited on the MNs for glucose detection. The MN electrodes showed good sensitivity and linearity, and the feasibility of glucose detection was demonstrated in an in vivo mouse study.
