Chaotropes are long known to destabilize protein assemblies and folding. We report that a boron cluster ion, as a weakly coordinating superchaotrope, can paradoxically stabilize protein folding even under extended thermal stresses while broadly inhibiting specific and nonspecific protein-protein interactions at millimolar concentrations for multiple proteins. Thermodynamic and kinetic investigations suggest that the boron cluster ion reduced the association rates of protein association and rendered protein-associative interactions entropically unfavorable.

Deep-ultraviolet photodetectors have promising applications in both civil and military fields, due to the advantage of effective light response without an external power supply. In this work, we proposed a self-powered deep-ultraviolet photodetector based on a p-CsCuI/n-ZnGaO heterojunction fabricated by a pulsed laser deposition technique. Under 260 nm illumination and 0 V bias, the photodetector exhibited a maximum responsivity and specific detectivity of 1.

The selective and rapid identification of alcohol vapors, including isomers and homologues, is crucial for environmental monitoring and industrial safety. Herein, a high-performance cataluminescence (CTL) sensing platform based on Eu-doped GdO was developed to discriminate alcohol vapors. Temperature-modulated CTL responses were employed to encode both thermodynamic and kinetic information, generating distinctive molecular fingerprints for tested alcohols to enable effective substance differentiation.

Evolutionary constraints governing flagellar number in bacterial pathogens remain poorly understood. While related species are hyperflagellated, maintains strict monoflagellation through the FleQ-FleN regulatory circuit. Here, we demonstrate that FleN dosage is essential for maintaining monoflagellation and bacterial fitness.

The increasing demand for highly reliable sensors capable of anti-interference and sensitive detection of aerosol-associated hypochlorite (ClO) drives progress in luminescence-based sensing technologies. Inspired by collective behavioral patterns in bird flocks, we developed a "bird-like flock" time-domain sensing method through the utilization of functional long afterglow nanomaterials (AGNPs) for ClO detection. Particularly, by translating avian aggregation-separation-alignment behaviors into an algorithmic framework, we presented a new sensing mode based on simplifying time decay curves into interpretable temporal metrics.

Membrane vesicle (MV) production is a natural phenomenon in Gram-negative bacteria and represents an emerging synthetic biology tool for the secretion of biomolecules or bioproducts. Manipulation of membrane components has proven successful in enhancing MV production. However, the impact of membrane disruptions on strain fitness and protein composition warrants further investigation for the use of MVs in industrial bioprocesses.

To reduce the "window period" in HIV detection, most analytical methods require additional enzymes for signal amplification. Exempting challenges like primer interference and false positives in amplification strategies, we developed an amplification-free bioassay that uses CRISPR's potent cleavage activity and the competent sensitivity of single-nanoparticle analysis. An attomolar detection limit was achieved with adequate selectivity.

: In the early stage of presbycusis, patients experience reduced speech perception in noisy environments despite normal audiometry, normally known as hidden hearing loss. Diagnostic indicators like the reduced amplitude of ABR wave I, elevated extended high-frequency threshold (EHT), and decreased middle ear muscle reflex (MEMR) amplitude aim to identify biomarkers of peripheral auditory pathology but remain inconsistent. Mismatch negativity (MMN) is a cortical auditory evoked potential generated when the brain detects sound changes.

As emerging pollutants, microplastics are pervasive in marine, terrestrial, and atmospheric environments as well as human tissues due to their small size, large specific surface area, and strong adsorption capacity. Consequently, developing efficient and rapid methods for identifying and differentiating microplastics is critical. Herein, a novel pyrolysis-assisted cataluminescence (CTL) sensor array was constructed, capable of efficiently distinguishing seven distinct types of microplastic samples.

Introduction: Cochlear implant (CI) success is often assessed using subjective tests like word recognition scores (WRS). However, these tests are unsuitable for children, non-native speakers, and individuals with cognitive impairments. Mismatch negativity (MMN), an objective measure of cortical auditory processing, offers a promising alternative for evaluating speech perception.

Integrated cataluminescence (CTL) sensing for both identification and quantification has become the focus in gas-sensing methods. With the development of an integrated circuit, inspiration from electronic automation provided a convenient approach for the application of CTL sensors. Here, a global dielectric barrier discharge plasma system supported by a digital code is raised for the process-oriented sampling and gaseous dynamic dual-route reaction for the rapid quantitative and qualitative analysis of oxidative volatile organic compounds (OVOCs).

Biological systems are complex, encompassing intertwined spatial, molecular and functional features. However, methodological constraints limit the completeness of information that can be extracted. Here, we report the development of INSIHGT, a non-destructive, accessible three-dimensional (3D) spatial biology method utilizing superchaotropes and host-guest chemistry to achieve homogeneous, deep penetration of macromolecular probes up to centimeter scales, providing reliable semi-quantitative signals throughout the tissue volume.

bacteria are enriched on poly(ethylene terephthalate) (PET) microplastics in wastewaters and urban rivers, but the PET-degrading mechanisms remain unclear. Here, we investigated these mechanisms with KF-1, a wastewater isolate, by combining microscopy, spectroscopy, proteomics, protein modeling, and genetic engineering. Compared to minor dents on PET films, scanning electron microscopy revealed significant fragmentation of PET pellets, resulting in a 3.
