A molecularly imprinted polymer based on a novel polyaniline–zinc sulfide nanocomposite for electrochemical detection of trimethylamine N-oxide

Abstract

The generation of gut microbiota-derived Trimethylamine N-oxide (TMAO) from the metabolism of dietary L-carnitine and choline is associated with a high risk of major adverse effects in humans. For this...

Disposable paper-based screen-printed electrochemical immunoplatform for dual detection of esophageal cancer biomarkers in patients' serum samples

“…The Brown-Anson model formula 63 was employed for calculating the surface concentrations of SPE, BSA/anti-CYFRA21-1/SPE, and BSA/anti-TP53/SPE immunoplatforms as provided in eqn (11): I p = n 2 F 2 γ * Aυ (4 RT ) −1 T is room temperature, i.e. , 300 K, R depicts the gas constant (8.314 J mol −1 K −1 ), F signifies the Faraday constant, i.e.…”

Reduced Graphene Oxide Nanosheets Enhance the Sensitivity of p-Cresyl Sulfate Detection Using a Molecularly Imprinted Polymer-Based Electrochemical Sensor

“…The second part undergoes continuous sonication for 17 h in order to remove the template using equal parts of methanol and water as the solvent. The sonication method for removal of the template from the polymer matrix was chosen in accordance to the previous work as reported in the literature . This solution was further centrifuged and washed with DI water and was dried at 80 °C overnight.…”

Prussian Blue-Gold Nanohybrids Combined with Headspace Microextraction for Colorimetric/SERS Dual-Mode Sensing of Trimethylamine N-Oxide

“…Alternatively, developing TMAO sensors is a promising approach to realize facile TMAO quantitative analysis. Although several sensors based on either electrochemical, fluorescent, or colorimetric methods have been reported for TMAO assay, − the detection sensitivity and selectivity are still far from satisfactory and await to be improved to meet the clinical requirements. However, owing to the relatively physical and chemical inertness of TMAO, it is highly challenging to develop sensitive and selective TMAO sensors.…”
