Abstract null null This article reports the preparation of mesoporous layered nanohybrids of zinc chromium layered double hydroxide (Zn-Cr-LDH) and polyoxotungstate (POW) anions via an exfoliation-reassembling process. The hybridization of Zn-Cr-LDH and POW anions leads to forming a layer-by-layer intercalated structure with a randomly interconnected mesoporous nanoplate network composed of ‘restacked POW intercalated Zn-Cr-LDH nanosheets’ (Zn-Cr-WO). The gas-sensing performance of the pristine ...

Abstract null null Herein, the spinel CdGa2O4 and off-stoichiometric spinel CdGa2O4 (CdO-CdGa2O4) with 3D inverse opal spherical structure have been synthesized by the combination of ultrasonic spray pyrolysis technology and self-assembled hard-template method. The CdGa2O4, with band gap of 4.14 eV and baseline resistance of Mohm-level, exhibited excellent selectivity and high response to 1ppm formaldehyde. On the other hand, the CdO-CdGa2O4 composites (Cd:Ga atom ratio = 1.2:2), with band gap o...

Abstract null null In this work, a simple fluorescence sensing device based on an approach of solvent-free magnetic-tip microextraction into a single drop was developed. As proof-of-principle, the strategy was used to extract chloramphenicol (CAP). CAP was selectively recognized by a DNA-aptamer and replaced by a trigger in the assay. By combining DNA signal amplification, DNA walkers constructed DNA chains with G-quadruplex/protoporphyrin IX (PPIX) as the branches on the surface of the added Fe...

Abstract null null Early diagnosis and detection of drug-induced liver injury (DILI) is great significance for the effective prevention and treatment of patients with liver injury. Studies indicate that the up-regulation of peroxynitrite (ONOO ) levels in liver is profoundly involved in acetaminophen (APAP)-induced liver injury. Herein, we constructed diketopyrrolopyrrole (DPP)-based ratiometric fluorescent probes (DPP-DH-P and DPP-DEG-P) for detecting and imaging ONOO . Comparing two probes, DP...

Abstract null null The Li0.5La0.5TiO3 (LLTO) is a new sensing material demonstrating ultrafast response to H2S within one second. To further enhance the sensitivity, a LLTO-SnO2 core-shell structure was constructed by the assembly of thin SnO2 nanoflakes on the porous hollow LLTO spheres. The absorption and reaction activity of oxygen on the surface as well as the electron transfer processes were modified and discussed in detail. The formation of oxygen vacancy improves the onset potential of ox...

Abstract null null Fluorescent dyes have been considered as one of the most potential candidates for electrochemiluminescence (ECL) reagent due to the excellent photophysical and electrochemical characteristics in recent years. However, the severe self-absorption effect caused by narrow stokes shift inevitably limits its application for ECL. In this work, a new type of ECL emitter, 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene derivative, a BF2 complex of hydrazine-schiff base linked bispyrrole, na...

Abstract null null Ru-doped porous hollow SnO2 nanotubes were prepared by simple electrospinning method, and their crystal structures, morphologies, and formation mechanism of porous hollow nanotubes were fully elucidated. The sensor based on the porous hollow Ru-doped SnO2 nanotubes shows an excellent sensing response of ~340 with ultrafast response time of 0.58 s at 250℃ to 100 ppm acetone. Moreover, the sensor exhibits good stability and excellent selectivity. Finally, the mechanism of the en...

Abstract null null Perfluorooctance sulfonate (PFOS) is one of the most studied Per-and-polyfluoroalkyl substances (PFAS) due to its relatively high environmental ubiquity and toxicity. This study presented an ultra-sensitive voltammetric sensor for the detection of PFOS in tap water based on a glassy carbon electrode (GCE) modified with a thin coating of gold nanostar (AuNS) and electropolymerized molecularly imprinted polymer (MIP). The AuNS coating helps to enhance the voltammetric response o...

Abstract null null Smouldering fires are characterized by the production of early gas emissions that can include high levels of CO and Volatile Organic Compounds (VOCs) due to pyrolysis or thermal degradation. Nowadays, standalone CO sensors, smoke detectors, or a combination of these, are standard components for fire alarm systems. While gas sensor arrays together with pattern recognition techniques are a valuable alternative for early fire detection, in practice they have certain drawbacks—the...
