Abstract Uranyl ion (UO 2 2+ ) pollution is a serious environmental problem, and developing novel adsorption materials essential for UO monitoring removal. Although some progress achieved, it still challenging task to develop an material with indicating signal real‐time evaluation of the degree concentration. Herein, this paper describes smart photonic crystal hydrogel (PCH) material, which not only can be used function but also utilized removal based on chelation ligand groups in PCH...
Bisphenol A (BPA), one of the most abundantly produced endocrine disrupting chemicals, is widely used in everyday plastic products and thus must be monitored. Multimode sensing platforms are able to combine advantages different strategies while solving issues inaccurate test results single signal sensing. However, exploration this field limited due compromise conditions inevitable mutual interferences systems. Herein, we constructed a two-dimensional photonic crystal dually cross-linked...
The stimuli-responsive DNA hydrogel has attracted wide attention in the fields of chemical and biological sensing. However, it is still a challenge to integrate characteristics with low-cost, high mechanical strength, signal self-expression into simultaneously. Herein, 2D photonic crystal double network (2D PhC DN-DNA hydrogel) sensing platform developed via combining array selective recognition polyacrylamide (PAM)/DNA DN hydrogel. change configuration induced by specific target triggers...
A novel aptasensor platform has been developed for quantitative detection of adenosine triphosphate (ATP) based on a ratiometric surface-enhanced Raman scattering (SERS) strategy. The thiolated 3′-Rox-labeled complementary DNA (cDNA) is first immobilized the gold nanoparticle (AuNP) surface and then hybridizes with 3′-Cy5-labeled ATP-binding aptamer probe (Cy5-aptamer) to form rigid double-stranded (dsDNA), in which Cy5 Rox labels are used produce signals. In presence ATP, Cy5-aptamer...
Uranium, both radioactivity and chemical toxicity, poses significant environmental health risks when released through nuclear industry activities uranium mining. Sensitive detection of uranyl ions (UO₂²⁺) in wastewater is...
A simple, label-free, and visual photonic crystal-based β-lactamase biosensor was developed for β-lactam antibiotic inhibitor in which the penicillinase (a β-lactamase) immobilized on pH-sensitive colloidal crystal hydrogel (CCH) film to form (PCCH) biosensing film. The hydrolysis of penicillin G antibiotic) can be catalyzed by produce penicilloic acid, leading a pH decrease microenvironment PCCH film, causes shrink CCH triggers blue-shift diffraction wavelength. Upon addition inhibitor,...
In pH 5.5 PBS buffer, PVP selectively coordinated with Cr(<sc>vi</sc>), causing PVP-AgNPs aggregation, the solution color changed from bright yellow to orange, and characteristic absorption peak of PVP–AgNPs at 390 nm lowered, a new 530 appeared.
A new method based on biomass Fe-CDs with fluorescence properties and simulated oxidase activity colorimetric fluorometric dual-readout assay for highly effective detection of AA was established.
N,S-CDs with orange fluorescent emission were synthesized via a hydrothermal method using o -phenylenediamine and thiourea. A novel fluorometric for the determination of VB 12 based on IFE was established.
Herein, a novel type of phosphorus and iron-doped carbon dot (P,Fe-CD) with outstanding peroxidase activity excellent fluorescence performance was hydrothermally synthesized to colorimetrically fluorimetrically detect tannic acid (TA).
A simple 2DPPCH biosensor was developed for colorimetric detection of penicillin G and penicillinase inhibitors based on the enzymatic hydrolysis reaction between penicillinase.
Abstract A colorimetric assay for the determination and quantification of ascorbic acid (AA) is presented using silver nanoparticle (AgNP) single‐walled carbon nanotube (AgNP/SWCNT) nanocomposites prepared a microwave‐assisted method. The AgNP/SWCNT possessed oxidase‐like properties toward 3,3′,5,5′‐tetramethylbenzidine (TMB) could catalyze oxidation TMB to form blue product (λ max = 652 nm) in absence H 2 O . AA can specifically inhibit TMB, resulting decline absorbance value colour fading....
MicroRNAs (miRNAs) play crucial regulatory roles as post-transcriptional regulators for gene expression and serve promising biomarkers diagnosis prognosis of diseases. Herein, a dual-signal amplification method has been developed sensitive selective detection miRNA based on rolling circle (RCA) enzymatic repairing (ERA) with low nonspecific background. This strategy designs padlock probe that can be cyclized in the presence target to initiate RCA reaction, after which TaqMan probes are...
Herein, a novel liquid crystal microarray (LCM) film with optical regulation ability is first constructed by combining crystals (LC) and the highly ordered microporous structure of inverse opal photonic (IOPhCs). The LCM films are fabricated infiltrating LC molecules into polymer IOPhCs, their properties very different from those without LC. Interestingly, property can be controlled changing orientation molecules, which varies interfacial force. In combination polarization images, spectral...
