摘要：
A novel and ultrasensitive electrochemiluminescent (ECL) bioassay has been developed for the detection of atrazine (ATZ), whereby bifunctional S, N-codoped carbon dots (S, N-CDs) and activated mesoporous bicarbons (BCs) have been innovatively integrated to synergistically amplify the ECL signal. When endogenous dissolved O2 is used as a coreactant, its sluggish reduction hinders the enhancement of ECL intensity of the luminophore, thus restricting its further application in bioanalysis. Here, bifunctional S, N-CDs severe as not only the ECL luminophore but the coreaction accelerator of dissolved O2 to generate more intermediates to boost the coreaction without using any other coreactant and coreaction accelerator. The as-formed nanoarchitectures of BCs possess enlarged surface area as the nanocarriers. They could provide adequate active sites for immobilization of tyrosinase (Tyr), which greatly prompts the ECL bioassay applications. Such a smart integration of bifunctional S, N-CDs, activated mesoporous BCs and the enzyme inhibition reaction achieves a unique and attractive high-performance signal-on ECL bioassay, realizing ultrasensitive detection of ATZ. Under the optimal condition, this bioassay exhibits two linear ranges, from 0.0001 to 0.01 μg L−1 and 0.01–20 μg L−1 with a detection limit of 0.08 ng L−1 at signal to noise ratio of 3. The as-fabricated assay is sensitive and economical, opening a new way for the enhancement of ECL signal output and a versatile strategy for ultrasensitive ECL bioanalysis. © 2019 Elsevier B.V.

摘要：
A simple, facile and sensitive photoelectrochemical (PEC) bioassay protocol for metronidazole (MNZ) detection in common oral medicine samples has been proposed under visible-light irradiation, where novel hierarchical coral-like g-C 3 N 4 nanoarchitectures (cg-C 3 N 4 ) have been first explored as PEC sensing platform. Featured with the unique nanostructures (e.g., interlaced porous network architecture, and open boundaries), the as-formed cg-C 3 N 4 nanoarchitectures not only efficiently inhibit the recombination of photogenerated electron-hole but also enable the immobilization of capture antibodies as well as the antibody-antigen binding efficiency fluently, thus amplifying the photocurrent response. This newly constructed PEC immunoassay displays excellent performance for MNZ determination with high sensitivity and selectivity. Under the optimal condition, this bioassay protocol exhibits a linear range of 0.01–100 µM with a detection limit of 0.005 µM at signal to noise ratio of 3. The resulting PEC immunoassay has been proved to be applicable for sensing MNZ in common oral medicine samples. © 2018 Elsevier B.V.

摘要：
A unique split-type photoelectrochemical (PEC) immunoassay has been constructed for detection of low-abundance biocompounds (lysozyme, Lyz, used in this case) via a new trigger strategy by disintegrating bioconjugates of dopamine-grafted silica nanospheres (DA@SiO2NSs) for signal amplification. The preferred electron donor assembly of DA@SiO2NSs is first used as a molecular printboard for positioning anti-Lyz secondary antibody (Ab2) through an amide reaction. With specific immunoreactions in a high-binding microplate, a sandwich immunoassay, the DA@SiO2NSs-based bioconjugate is achieved. By initiating the disintegration of the bioconjugates via acid etching, numerous electron donors of DA are released, thus efficiently triggering hole-trapping with amplified signals obtained. The smart integration of ZnIn2S4-based heterojunctions as photoactive material, a split-type detection mode, and a new trigger strategy by disintegrating the DA@SiO2NSs-based bioconjugate offer an attractive high-throughput signal-on PEC immunoassay for detection of Lyz. Such an unusual PEC sensor exhibits an outstanding linear response to the concentration in the range between 0.002 and 500 ng mL-1, and the detection limit is as low as 0.6 ppt (S/N = 3). The as-fabricated assay is cost-effective and sensitive. It has been successfully used for measuring Lyz in real samples, which demonstrates great promise for practical applications. © Copyright 2018 American Chemical Society.

摘要：
Owing to the lack of chromophores and ionizable functional groups, it is a significant challenge to determine perfluorooctane sulfonyl fluoride (PFOSF) by traditional high-performance liquid chromatography or liquid chromatography/mass spectrometry, especially at a low concentration. In this work a unique photoelectrochemical (PEC) sensing strip has been developed for the first time for the detection of PFOSF. The sensing strip is cost effective and disposable, whereby BiOI nanoflake arrays are fabricated on a home-made screen-printed electrode through a facile one-step in-situ electrodeposition process, and then the molecule tags (i.e., molecularly imprinted polymers) for PFOSF are subsequently grafted on the surface. Benefitting from a three-dimensional interconnected framework, the as-fabricated sensing strip has a rapid response to the interfacial steric hindrance effect between the sensing platform and the target analyte of PFOSF. The elaborated PEC sensor exhibits a outstanding linear response to a concentration of PFOSF ranging from 0.05 to 500.0 ppb and a detection limit down to 0.01 ppb (S/N = 3) Furthermore, our low-cost and highly sensitive sensor has been further explored to detect PFOSF in real water samples, showing satisfactory results. © 2018 Elsevier B.V.

摘要：
Erythrocyte-like hierarchical α-Fe<inf>2</inf>O<inf>3</inf>/Bi<inf>2</inf>WO<inf>6</inf>nanocomposites were synthesized by a simple and convenient hydrothermal method. The composites were assembled from α-Fe<inf>2</inf>O<inf>3</inf>/Bi<inf>2</inf>WO<inf>6</inf>nanoplates. The structures of α-Fe<inf>2</inf>O<inf>3</inf>/Bi<inf>2</inf>WO<inf>6</inf>nanocomposites were characterized by XRD, TEM, BET and gas sensing properties toward xylene were investigated in detailed. The sensors based on self-assembled α-Fe<inf>2</inf>O<inf>3</inf>/Bi<inf>2</inf>WO<inf>6</inf>nanoplates show much enhanced sensing performances to xylene than that of pure Bi<inf>2</inf>WO<inf>6</inf>. The sensing performance using 10 wt% α-Fe<inf>2</inf>O<inf>3</inf>/Bi<inf>2</inf>WO<inf>6</inf>reaches the highest response (S = 13.5) for the detection of 100 ppm xylene. Significant enhancement of the response and selectivity to xylene can be attributed to the formation of heterostructure and the synergistic catalytic activity from α-Fe<inf>2</inf>O<inf>3</inf>and surface decorated WO<inf>4</inf><sup>2–</sup>.<br/> ©2016, Springer Science+Business Media New York.

摘要：
Effective decomposition of perfluorooctanoic acid (PFOA) has received increasing attention in recent years because of its global occurrence and resistance to most conventional treatment processes. In this study, the complete mineralization of PFOA was achieved by the UV-photolysis of nitrate aqueous solution (UV/Nitrate), where the in-situ generated nitrogen dioxide radicals (center dot NO2) efficiently mediated,the degradation of PFOA. In particular, when the twinborn hydroxyl radicals were scavenged, the production of more center dot NO2 radicals realized the complete mineralization of PFOA. DFT calculations further confirm the feasibility of PFOA removal with center dot NO2. Near-stoichiometric equivalents of fluoride released rather than the related intermediates were detected in solution after decomposition of PEOA, further demonstrating the complete degradation of PFOA. Possible PFOA degradation pathways were proposed on the basis of experimental results. This work offers an efficient strategy for the complete mineralization of per fluorinated chemicals, and also sheds light on the indispensable roles of nitrogen dioxide radicals for environmental pollutants removal.

摘要：
Triphenyl Phosphate (TPhP), as a typical model of organophosphorus flame retardants (OPFRs), has been regarded as emerging environmental contaminants of health concern. In this study, a rapid and highly sensitive visible-light-response PEC sensor has been developed for the detection of Triphenyl Phosphate (TPhP) using electrospun template directed molecularly imprinted nanofibers modified BiOI nanoflake arrays (BiOINFs) as a photoactive electrode. The molecularly imprinted electrospun nanofibers (labeled as MI-ESNFs) were carefully characterized by scanning electron microscopy (SEM), UV spectra, FTIR spectra measurements and various electrochemical techniques. Under the optimized experimental conditions, the photoelectrochemical response was linearly proportional to the logarithm value of TPhP concentrations in the range of 0.01ngmL−1 to 500ngmL−1. Meanwhile, the sensor exhibited high selectivity and stability. © 2017 Elsevier B.V.

摘要：
A rapid and highly sensitive photoelectrochemical (PEC) method has been proposed for the determination of trace amounts of chromium in water samples under visible-light irradiation. Here, a unique nanostructured hybrid of formate anion incorporated graphitic carbon nitride (F-g-C<inf>3</inf>N<inf>4</inf>) is smartly integrated with a Cr(VI) ion-imprinted polymer (IIP) as a photoactive electrode (denoted as IIP@F-g-C<inf>3</inf>N<inf>4</inf>). The nanohybrid of F-g-C<inf>3</inf>N<inf>4</inf>exhibits an enhanced charge separation with substantially improved PEC responses versus g-C<inf>3</inf>N<inf>4</inf>. The newly designed IIP@F-g-C<inf>3</inf>N<inf>4</inf>PEC sensor exhibits high sensitivity and selectivity for the determination of Cr(VI) because it offers efficient photogenerated electron reduction toward Cr(VI). The PEC analysis is highly linear over Cr(VI) concentrations ranging from 0.01 to 100.00 ppb with a detection limit of 0.006 ppb (S/N = 3). Our approach can be used to detect Cr(VI), Cr(III) and the total chromium level in aqueous solution through oxidation of Cr(III) to Cr(VI) and the determination of the total chromium as Cr(VI). In practical applications, this low-cost and sensitive assay has been successfully applied for speciation determination of chromium in environmental water samples. ©2016 Elsevier B.V.

摘要：
A rapid and ultrasensitive signal-off photoelectrochemical sensor has been developed under visible-light irradiation, for the detection of perfluorooctanoic acid (PFOA), especially low level PFOA present in environment, whereby a novel nanostructured probe made of molecularly imprinted polymer (MIP) modified AgI nanoparticles-BiOI nanoflake arrays (AgI-BiOINFs) is designed as the photoactive electrode (denoted as MIP@AgI-BiOINFs). Here, the unique nanoarchitectured hybrid of AgI-BiOINFs was first in situ synthesized via a facile successive ionic layer adsorption and reaction (SILAR) approach and then employed as a matrix to graft the recognition element of MIP. Such a newly designed PEC sensor exhibits high sensitivity and selectivity for the determination of PFOA. The PEC analysis is highly linear over the PFOA concentration ranging from 0.02 to 1000.0. ppb with a detection limit of 0.01. ppb (S/. N=3). This value obtained by using the facile PEC sensor is comparable to the results obtained by using well-established liquid chromatography-tandem mass spectrometry (LC-MS/MS). Toward practical applications, this low-cost and sensitive assay was successfully applied to measure PFOA in real water samples. © 2015 Elsevier B.V..

摘要：
Driven by the urgent demand for the determination of low level perfluorooctanoic acid (PFOA) present in environment, a novel electrochemiluminescence (ECL) sensor has been first developed for the detection of PFOA using the molecularly imprinted polypyrrole modified two-dimensional ultrathin g-C<inf>3</inf>N<inf>4</inf>(utg-C<inf>3</inf>N<inf>4</inf>) nanosheets as a cathodic ECL emitter with S<inf>2</inf>O<inf>8</inf><sup>2-</sup>as coreactant. The prepared molecularly imprinted polymer (MIP) functionalized utg-C<inf>3</inf>N<inf>4</inf>nanosheets (MIP@utg-C<inf>3</inf>N<inf>4</inf>) exhibit a stable and significantly amplified ECL signal. It is found that the targets of PFOA could be efficiently oxidized by the electro-generated strong oxidants of SO<inf>4</inf><sup>-</sup>(from the reduction of coreactant S<inf>2</inf>O<inf>8</inf><sup>2-</sup>), thus leading to a low yield of the excited utg-C<inf>3</inf>N<inf>4</inf>(g-C<inf>3</inf>N<inf>4</inf>*) and finally a decrease in ECL signal. Based on this, a highly sensitive and selective MIP@utg-C<inf>3</inf>N<inf>4</inf>-based signal-off ECL sensor is developed for sensing PFOA. Such a newly designed ECL sensor exhibits highly linear over the PFOA concentration in two ranges, from 0.02 to 40.0 ng mL<sup>-1</sup>and 50.0-400.0 ng mL<sup>-1</sup>. The detection limit (S/N = 3) is estimated to be 0.01 ng mL<sup>-1</sup>(i.e. 0.01 ppb), comparable to the results obtained by using well-established liquid chromatography-tandem mass spectrometry (LC-MS/MS). Toward practical applications, this low-cost and sensitive assay was successfully applied to measure PFOA in real water samples, showing fine applicability for the detection of PFOA in real samples. ©2015 Elsevier B.V.

摘要：
A novel and highly sensitive visible-light photoelectrochemical (PEC) sensor for the detection of 2,4-D has been developed using a nanocomposite of molecularly imprinted gold nanoparticles-polypyrrole polymer (MIP) modified BiOI nanoflake arrays (BiOINFs) as a photoactive electrode (labeled as MIP@BiOINFs). Our results demonstrate that the smart combination of BiOINFs with MIP offers a high-performance photoactive sensing platform. It features the intrinsically excellent visible-light responsive properties of BiOI and prominent recognition ability from MIP. The designed MIP@BiOINF composite dramatically facilitates the PEC determination of 2,4-D. The detection limit for 2,4-D is found to be as low as about 0.04 ng mL<sup>- 1</sup> (S/N = 3). Moreover, the resulting sensor could be used to detect 2,4-D in spiked soil samples. ©2014 Published by Elsevier B.V.
