Abstract
Although luminescence metal organic framework (MOFs) has displayed the significant advantages, the limitations in the electrochemical performance (e.g. rapid charge recombination rates and inadequate charge transport) limited the sensing application of MOFs. Herein, a novel Cu-MOFs/BiVO4 nanorod-based electrogenerated chemiluminescence (ECL) sensor has been developed. Firstly, Cu-MOFs with strong luminescence were synthesized via the three-layer approach as ECL emitter. Furthermore, BiVO4 nanorods was modified on the electrode as the actuator to improve the electrochemical activity of Cu-MOFs in the ECL process. As an n-type semiconductor, BiVO4 formed a complementary structure with p-type semiconductor Cu-MOF. Therefore, electrons in the conduction band of BiVO4 transferred to that of Cu-MOF. As a result, more electrons reacted with coreactant on the surface of Cu-MOF, which effectively enhanced the ECL performance of 2D Cu-MOFs nanosheets. As a result, the quantitation of KRAS gene was realized in the linear range of 0.1 pM-1 nM with a detection limit of 0.02 fM. Moreover, the detection of KRAS gene in actual colorectal cancer samples was also carried out with good recovery, which offered a broad application possibility for ECL research and clinical analysis.

Development of novel nanocomposite-modified photoelectrochemical sensor based on the association of bismuth vanadate and MWCNT-grafted-molecularly imprinted poly(acrylic acid) for dopamine determination at nanomolar level. Talanta 2024; 266:125044. [PMID: 37586281 DOI: 10.1016/j.talanta.2023.125044] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2023] [Revised: 08/03/2023] [Accepted: 08/05/2023] [Indexed: 08/18/2023]
Abstract
This study proposes the development of a new photoelectrochemical (PEC) sensor for the determination of dopamine (DA) at nanomolar levels. The PEC sensor was based on a physical mixture of bismuth vanadate (BiVO4) with nanocomposite molecularly imprinted poly(acrylic acid) (MIP-AA) grafted onto MWCNTox by using the surface-controlled radical polymerization strategy with an INIFERTER reagent. XRD, diffuse reflectance spectroscopy (DRE), SEM, TEM, and TGA were employed to characterize the materials. Photoelectrochemical analyses were carried out with GCE/BiVO4/MIP-AA sensor under visible light using a potential of 0.6 V, phosphate buffer (0.1 mol L-1) at pH 7.0, and modifying the GCE with a film composed of monoclinic BiVO4 at 3.5 mg mL-1 and nanocomposite MIP prepared with acrylic acid (MIP-AA) at 0.1 mg mL-1. The proposed method using the GCE/BiVO4/MIP-AA sensor presented a limit of detection (LOD) of 2.9 nmol L-1, a linear range from 9.7 to 150 nmol L-1 and it was successfully applied for analysis of DA in urine samples using external calibration curve yielding recovery values of 90-105%. Additionally, the proposed PEC sensor allowed DA determination without interference from uric acid, ascorbic acid, epinephrine, norepinephrine, and other unwanted interferences.

Abstract
The fact that antioxidants scavenge free radicals in the human body and naturally treat many health problems that will occur in this way has increased the consumption of antioxidant-containing foods. However, consumption of artificially prepared antioxidants could cause cancer. Therefore, antioxidants from natural sources are preferred. Quercetin is an antioxidant present in natural samples. In this article, multi-walled carbon nanotubes (MWCNTs), a polymer composite (PC) consisting of a mixture of 15% (by mass) polystyrene (PST), 15% (by mass) polyacrylonitrile (PAN) and 70% (by mass) polyindole (PIN), and semiconducting BiVO4 were used to prepare electrodes, and then a photosensitive ITO/MWCNTs@PC@BiVO4-based sensor was fabricated for quercetin detection. Quercetin was analyzed via the photosensitive ITO/MWCNTs@PC@BiVO4 sensor in 0.1 M phosphate buffered saline (pH 7.4) solutions including various quercetin concentrations. The constructed quercetin sensor displayed a wide linear response between 10 and 200 μM and a limit of detection of 0.133 μM. The developed photosensitive ITO/MWCNTs@PC@BiVO4 demonstrated a high sensitivity (442 µA mM-1 cm-2), good reproducibility (relative standard deviation 3.6%), high selectivity and long-term stability (>49 days) towards quercetin sensing. The photoelectrochemical sensor was then applied to detection of quercetin in black tea as a real-life sample. Our study could lead to the development of novel photosensitive PC polyphenol sensors.

Abstract
A ternary nanocomposite photoelectrode composed of cadmium sulfide (CdS), polyaniline (PANI), and bismuth vanadate (BiVO4) was successfully designed by combining cyclic voltammetry (CV) with electrochemical deposition and high-temperature calcination. The first synthesized CdS/PANI/BiVO4 composite was used as a photoelectrochemical (PEC) monitoring platform for glutathione (GSH). The ternary CdS/PANI/BiVO4 nanocomposites exhibited higher PEC activity, which was attributed to the accelerated electron transfer by the loading of CdS and PANI, which enables the material surface to better adsorb the electrons separated by GSH, thereby oxidizing it into GSSH. The photoanodes were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), UV-vis diffuse reflectance spectroscopy, and photoelectrochemical experiments. Under the optimal experimental conditions, the BiVO4 electrode modified with CdS and PANI exhibited a linear response in the concentration range of 0.1-20 μM with a sensitivity of 0.669 μA mM-1 cm-2 and a detection limit of 40 nM. Moreover, the PEC sensor exhibits good reproducibility and long-term stability. In summary, the designed materials have excellent electrochemical properties, which make them ideal candidates for PEC detection of GSH.

Abstract
The quantification of 3-nitro-l-tyrosine (NO2-Tyr), an in vivo biomarker of nitrosative stress, is indispensable for the clinical intervention of various inflammatory disorders caused by nitrosative stress. By integrating the unique features of BiVO4 and MoS2 with matching bandgap energies, electrode materials with amplified response signals can be developed. In this regard, we introduce a hydrothermally synthesized bismuth vanadate sheathed molybdenum disulfide (MoS2@BiVO4) heterojunction as a highly sensitive electrode material for the determination of NO2-Tyr. Excellent electrochemical behavior perceived for the MoS2@BiVO4 augments the performance of the sensor and allows the measurement of NO2-Tyr in biological media without any time-consuming pretreatments. The synergistic interactions between BiVO4 and MoS2 heterojunctions contribute to low resistance charge transfer (Rct = 159.13 Ω·cm2), a reduction potential Epc = -0.58 V (vs Ag/AgCl), and a good response range (0.001-526.3 μM) with a lower limit of detection (0.94 nM) toward the detection of NO2-Tyr. An improved active surface area, reduced charge recombination, and high analyte adsorption contribute to the high loading of the biomarker for improved selectivity (in the presence of 10 interfering compounds), operational stability (1000 s), and reproducibility (six various modified electrodes). The proposed sensor was successfully utilized for the real-time determination of NO2-Tyr in water, urine, and saliva samples with good recovery values (±98.94-99.98%), ascertaining the reliability of the method. It is noteworthy that the electrochemical activity remains unaffected by other redox interferons, thus leading to targeted sensing applications.
