Ascribing to the abundance of Ti element, exceptional electrical conductivity, and electrocatalytic performance, titanium carbide MXene (Ti 3 C 2 T x , MX) is considered as an ideal conductive matrix employed for in situ preparation promising TiO NPs@MX/reduced graphene oxide (rGO) heterojunction electrodes uric acid (UA) detection. However, incapability achieving controllable growth synthesis nanoparticles (NPs) on MX nanosheets a bottleneck fabricating optimal NPs@MX hybrid. Herein, “on‐site transformation strategy” developed synthetize NPs@MX/rGO platform controllably by electrochemical oxidizing at various treatment times. The proposed approach allows greater operability grow NPs surface nanosheets. present linear voltammetric response toward UA concentration range 0.003–0.3 0.3–300 μ m low detection limit 0.78 n ( S / N = 3). Additionally, handheld system with smartphone readout point‐of‐care health monitoring, enabling fast, precise, specific recognition real urine samples. study provides facile fabricate future use other biomolecules'

Bimetallic MOFs-Based Electrodes for the Simultaneous Electrochemical Detection of Epinephrine and Nor-Epinephrine

Journal of The Electrochemical Society, Journal Year: 2024, Volume and Issue: 171(9), P. 097501 - 097501

Published: Sept. 2, 2024

We designed a bi-metallic Co-Ni/BTC/4,4′-BiPy metal organic frameworks (MOFs) as an electrode material for the electrochemical detection of epinephrine and nor-epinephrine. The MOFs were synthesized by solvothermal method. Following this, bimetallic modified with BTC amine rich 4,4′-BiPy to improve charge transfer kinetics through non-covalent π – interaction. This was employed sensing platform simultaneous exhibited 10–50 μM linear range limit 0.724 ± 0.128 (N = 3) 0.815 0.124 3), sensitivity 0.583 0.505 μA −1 cm −2 corresponding nor-epinephrine detection. Finally, sensor tested in blood urine samples spiked known concentrations Results confirmed usefulness proposed clinical samples.

Sensitive and Stable Electrochemical Sensor for Folic Acid Determination Using a ZIF-67/AgNWs Nanocomposite

Biosensors, Journal Year: 2022, Volume and Issue: 12(6), P. 382 - 382

Published: May 31, 2022

An electrochemical sensor using silver nanowires (AgNWs)-doped with a zeolite-like metal-organic framework (ZIF-67) was developed for highly sensitive and stable determination of folic acid (FA). The ZIF-67/AgNWs nanocomposite prepared by one-step reaction via template method drop-coated onto the surface screen-printed carbon electrode (SPCE) to form ZIF-67/AgNWs@SPCE sensing platform. square wave voltammetry (SWV) curve this platform measured in an electrolyte solution containing FA under optimum experimental conditions. redox peak current (IFA) increased increases concentration (CFA). There linear relationship between IFA CFA range 0.1 μM 10 μM, limit 30 nM. used as which maintained good stability over 7 days showed performance real samples high recovery rate (100.9-102.1%, n = 6).
