Wearable electrophysiological interfaces demand bioelectrodes that combine low-impedance, stable ion-electron transduction with high mechanical deformability, yet these requirements remain fundamentally incompatible in existing systems. Here, we present a nonpolarizable stretchable dry electrode based on a bead-on-string Ag/AgCl heterostructure, in which AgCl nanoparticles (NPs) are selectively assembled along percolated silver nanowire networks embedded within an elastomer matrix. This architecture spatially decouples Faradaic reaction sites from conductive pathways, constructing abundant, mechanically robust Ag/AgCl heterointerfaces for efficient ion-electron transduction while preserving continuous electron transport under large deformation. By systematically tuning the size of AgCl NPs (50-800 nm), the spatial distribution and interfacial length scale of Faradaic domains are optimized to maximize electrochemical performance. The resulting electrode achieves ultralow interfacial impedance (49 kΩ, 10 Hz), stable electrode potentials, and tolerance to severe mechanical deformation (ε > 370%), with minimal degradation over 500 stretch cycles. It enables low-noise, high-fidelity signal acquisition in the low-frequency regime, effectively suppressing motion artifacts and maintaining stable operation over 120 days of storage in air. When integrated with a spatiotemporal neural network for electrooculography decoding, the system achieves 98% accuracy in hands-free game control, demonstrating a robust paradigm for next-generation wearable bioelectronics.

A novel gas-sensing material and photocatalyst was successfully obtained by decorating Ag/AgCl nanoparticles on the W 18 O 49 nanorods through a clean photochemical route. The as-prepared samples were characterized using combined techniques of X-ray diffractometry, electron microscopy , energy dispersive X-ray spectrometry , and X-ray photoelectron spectroscopy. Gas-sensing measurements indicate that the Ag/AgCl/W 18 O 49 NRs sensors exhibit superior reducing gas-sensing properties to those of bare W 18 O 49 NRs, and they are highly selective and sensitive to NH 3 , acetone, and H 2 S with short response and recovery times. The Ag/AgCl/W 18 O 49 NRs photocatlysts also possess higher photocatalytic performance than bare W 18 O 49 NRs for degradation of methyl orange under simulated sunlight irradiation. Possible mechanisms concerning the enhancement of gas-sensing and photocatalytic activities of the Ag/AgCl/W 18 O 49 NRs composite were proposed.

Controlled silver chloride (0.01–0.50 mol%) and tin co-doped micro-spherical titania (AgCl@Sn-TiO 2 ) with enhanced visible range absorption is prepared through hydrothermal synthesis. Multi-element doped rutile TiO 2 nanocrystalline electron transporting layer (ETL) in perovskite solar cell (PSC) is reported for the first time, which uplifts the photovoltaic performance comparing with undoped TiO 2 electrodes. Theoretical DFT studies, investigating the change in electronic density of states with respect to the doping are performed. An optimum efficiency of 10.4% was achieved for 0.01% doped AgCl@Sn-TiO 2 , which provided highest efficiency with higher stability over 650 h comparing to undoped TiO 2 (10.0%) ETL based PSC prepared under the same ambient conditions. This report proves that, the AgCl@Sn-TiO 2 is one of the efficient materials having good potential for application in photoenergy conversion devices and may provide new insight into the design of advanced perovskite solar cells with titania based electron transport materials.

A structurally stable AgCl-COOH MWCNT/PES composite membrane was designed and fabricated by combining phase conversion and post-treatment techniques, which can solve the serious membrane fouling in industrial wastewater treatment. The carboxylation of MWCNTs not only enhanced their dispersion but also facilitated their binding with silver chloride, resulting in a stable composite structure that significantly improved contaminant degradation capabilities. The post-treatment technique increased the membrane’s water purification flux by 150 % (reaching 520 L·m 2 ·h −1 ·bar −1 ) while maintaining a high BSA retention rate of 95 %. Additionally, the composite membrane demonstrated excellent photocatalytic antifouling properties, with a flux recovery rate of 91.8 % under UV irradiation, and exhibited more than 99 % inhibition of Escherichia coli. This method provides a scalable solution for enhancing the performance of PES membranes in wastewater treatment applications.

Ag/AgCl-decorated layered lanthanum oxide (La2O3) and niobium pentoxide (Nb2O5) plasmonic photocatalysts are fabricated through an ionic liquid-mediated co-precipitation method. Scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), powder X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), diffuse reflectance spectroscopy (DRS), and photoluminescence (PL) techniques were used to illustrate the physicochemical properties of the materials. The photoactivity was evaluated for the degradation of Acid Blue 92 (AB92) azo dye, a typical organic contaminant from the textile industry, and U251 cancer cell inactivation. According to the results, Nb2O5–Ag/AgCl was able to remove >99% of AB92 solution in 35 min with the rate constant of 0.12 min−1, 2.4 times higher than that of La2O3–Ag/AgCl. A pH of 3 and a catalyst dosage of 0.02 g were determined as the optimized factors to reach the highest degradation efficiency under solar energy at noon, which was opted to have the highest sunlight intensity over the reactor. Also, 0.02 mg/mL of Nb2O5–Ag/AgCl was determined to be of great potential to reduce cancer cell viability by more than 50%, revealed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and mitochondrial membrane potential (MMP) examinations. The mechanism of degradation was also discussed, considering the key role of Ag0nanoparticles in inducing a plasmonic effect and improving the charge separation. This work provides helpful insights to opt for an efficient rare metal oxide with good biocompatibility as support for the plasmonic photocatalysts with the goal of environmental purification under sunlight.

Maintenance-free, cost-effective, and long-lasting potentiometric sensors are highly anticipated for marine detection. Solid-state silver/silver chloride (Ag/AgCl) is considered the most suitable non-polarizable electrode for that purpose. However, the conventional fabrication of thin-film or porous Ag/AgCl electrodes has limitations in the case of simultaneous cost-effectiveness and stability endurance. In the present study, the multi-walled carbon nanotube (MCNT)/Ag/AgCl composite electrode with a 70 mg/cm 2 Ag load was prepared, having nanoporous MCNT/Ag conductive skeleton, and a three-dimensionally spreading Ag/AgCl thin layer. The prepared MCNT/Ag/AgCl composite electrode showed an excellent electrode performance, including low resistance, high exchange current density , and stable potential with long-term stability and low cost. The process kinetics and self-repairing mechanism between Ag and AgCl with the help of MCNT were elucidated. The usage of MCNT/Ag/AgCl composite electrode as a solid-state reference electrode and ocean electric field sensor was successfully evaluated, which provides a promising marine potentiometric sensor application for this nanoporous metal composite electrode via a novel preparation method.

Fabricated a broad-spectrum responsive AgCl@Ag photocatalyst with SPRE. • AgCl@Ag exhibits 2.4-fold higher MRR than TiO 2 under visible light. • Revealed SPRE-enhanced ·OH generation and synergistic removal mechanism. To overcome the ultraviolet (UV) light limitation of conventional TiO 2 -based photocatalysis-assisted polishing, AgCl@Ag composite particles with surface plasmon resonance effect (SPRE) were prepared via a precipitation-chemical reduction method. Their morphology, phase composition, surface chemistry, and optical absorption were characterized by SEM, XRD, XPS, and UV–Vis. Photocatalytic activity and polishing performance on single-crystal SiC were systematically compared with commercial TiO 2 under both UV and visible light. The AgCl@Ag particles showed uniform size, regular morphology, no surface impurities, and broad-spectrum absorption. Under UV light, both AgCl@Ag and TiO 2 achieved >90% methyl orange degradation within 30 min, with comparable polishing performance: AgCl@Ag yielded an MRR of 86.7 nm·h −1 and a surface roughness Sa of 3.25 nm, versus 77.0 nm·h −1 and 3.28 nm for TiO 2 . Under visible light, significant differences emerged. TiO 2 degraded only 13% of methyl orange in 30 min, with an MRR of 22.8 nm·h −1 and Sa of 6.78 nm. In contrast, AgCl@Ag achieved >55% degradation, an MRR of 55.0 nm·h −1 , and Sa of 4.93 nm under the same conditions. The SPRE of AgCl@Ag promotes photogenerated charge carrier separation, enabling ·OH radical generation that synergistically forms and mechanically removes the surface oxide layer on SiC.

AgCl/Ag@MOF(Ag) nanocomposites have been successfully fabricated through a simple and quick one-pot reflux approach for the first time, where AgCl/Ag nanoclusters are stabilized on the sheet-like MOF(Ag) surface. The as-prepared Ag-based MOFs fluorescent probe shows high fluorescence intensity and excellent fluorescence stability for sensing of tetracycline antibiotics (TCs) through mechanisms involving inner filter effect (IFE) and static quenching. The experimental results show that the detection concentration ranges for tetracycline (TET), chlortetracycline (CTC), and oxytetracycline (OTC) were 10–80 μM, 10–60 μM, and 10–30 μM, and with the detection limits of 2.59 nM, 1.36 nM, and 1.43 nM, respectively. The high sensitivity and selectivity of the fluorescent probe for TCs offers novel perspectives on utilizing supported MOFs as fluorescent probes for trace TCs detection in food by a fast, simple, and reliable method.

Inorganic arsenic threatens human health due to its high mobility and toxicity. In this work, rapid and effective treatment of As(III) wastewater was achieved by Z-Scheme photocatalyst (ZnFe 2 O 4 /Ag/AgCl). By means of peroxymonosulfate (PMS) activation, 50 mg/L As(III) was completely removed within 20 min under light irradiation. During photocatalytic system, free radicals ( SO 4 − , OH, O 2 − ) and non-radicals ( 1 O 2 ) were responsible for As(III) removal. The fast PMS activation was attributed to the loop conversion of Fe(III)/Fe(II) and Ag 0 /Ag + . Besides, density functional theory (DFT) calculations exhibited that Fe atoms were active sites for As(III) adsorption and Ag nanoparticles were spots for PMS activation. Specially, the dual active sites on photocatalyst could effectively minimize the distance between oxidizing product with arsenite molecular and thus facilitate As(III) fast oxidation.

Antibiotic contamination is increasing scrutinized recently. In this work, the Ag−AgCl/WO 3 /g-C 3 N 4 (AWC) nanocomposites were successfully synthesized using a two-step process involving electrostatic self-assembly and in-situ deposition for trimethoprim (TMP) degradation. The as-prepared photocatalysts were investigated and characterized by XRD, FTIR, XPS, TGA, SEM, TEM , UV–vis, PL and EIS. The experimental results indicated that 99.9% of TMP (4 mg/L) was degraded within 60 min when the concentration of AWC was 0.5 g/L. Reactive species scavenging experiments and electron spin resonance (ESR) experiments illustrated that superoxide radical (•O 2 − ) and photogenerated holes (h + ) were the main active species. The functional theory calculation and identification of intermediates via HPLC-MS revealed the possible degradation pathways of TMP. A double photoelectron-transfer mechanism in AWC photocatalyst was proposed. Five cycling photocatalytic tests and reactions under different solution matrix effects further supported that the AWC was a promising photocatalyst for the removal of TMP from the aquatic environment.

Direct detection of long-strand DNA by surface-enhanced Raman scattering (SERS) is a valuable method for diagnosis of hereditary diseases, but it is currently limited to less than 25-nt DNA strand in pure water, which makes this approach unsuitable for many real-life applications. Here, we report a 60-nt DNA label-free detection strategy without pretreatment by SERS with polyquaternium-modified Ag microcrystals derived from an AgCl cube. Through the reduction-induced decomposition, the size of the about 3 × 3 × 3 μm3AgCl cube is reduced to Ag, and the surface is distributed with the uniform size of 63 nm silver nanoparticles, providing a large area of a robust and highly electromagnetic enhancement region. The modified polycationic molecule enhances the non-specific electrostatic interaction with the phosphate group, thereby anchoring DNA strands firmly to the SERS enhanced region intactly. As a result, the single-base recognition ability of this strategy reaches 60-nt and is successfully applied to detect thalassemia-related mutation genes.Keywords:60-nt DNA direct detection;surface-enhance Raman scattering;Ag microcrystal;polycationic

An Ag@AgCl/Ag nanofilm/ZIF-8 composite photocatalyst was successfully constructed for the first time by loading Ag@AgCl and Ag nanofilm on the surface of ZIF-8 simultaneously via a simple deposition-photoreduction method. The formed Ag nanofilm was harnessed as a mediator to transfer photo-induced electrons from the plasmonic Ag@AgCl nanostructure to ZIF-8 for enhancing the photocatalytic reaction rate with visible light. The photocatalytic activity was evaluated by photocatalytic degradation of methylene blue (MB) under visible light irradiation. The first-order kinetic constant of MB degradation over Ag@AgCl/Ag nanofilm/ZIF-8 (14.762 h −1 ) was nearly 2 times of Ag@AgCl/ZIF-8 (7.932 h −1 ). The electrochemical impedance spectra, photoelectric conversion spectra and ESR DMPO-O 2 − species spectra revealed that AFZ had a lower resistance, higher photocurrent density and more generation of superoxide radical than those of AZ, meaning that the extended interface between Ag nanofilm and ZIF-8 could promote the quick electrons transfer and electron-hole pairs separation. This work provides a new type electrons transfer mediator in fabrication of efficient plasmonic photocatalysts.
