Enhanced simultaneous voltammetric detection of dopamine and uric acid using Au@Ni‐metal–organic framework‐modified electrode

Applied Organometallic Chemistry, Journal Year: 2024, Volume and Issue: 38(4)

Published: Jan. 13, 2024

A novel conductive Ni‐based metal–organic framework (MOF) decorated with Au nanoparticles (AuNPs; Au@Ni‐MOF) was developed and used as a drop‐cast thin‐film electrode to individually simultaneously quantify dopamine (DA) uric acid (UA). The Ni‐MOF composite synthesized using an in situ growth strategy involving the of [Ni 3 (BTC) 2 (H O) 6 ]n (BTC = 1,3,5‐benzenetricarboxylate) coordinatively unsaturated Ni (II) sites. powder then mixed AuNP solution produce Au@Ni‐MOF hybrid material. material employed surface modifier for screen‐printed carbon electrode, its efficacy detection DA UA assessed differential pulse voltammetry (DPV) cyclic voltammetry. sensor exhibited remarkable sensitivity, achieving low limits approximately 0.027 0.028 μM (S/N 3) simultaneous quantification UA, respectively. extensive linear range 0.5 1 mM, coupled excellent sensitivities 1.43 1.35 μA −1 cm −2 , Furthermore, performance human serum urine samples successfully validated DPV, which revealed outstanding recovery rates 93.8–105.0% minimal relative standard deviation below 3%. Moreover, exceptional dispersion stability, high selectivity, were attributed well‐arranged combination AuNPs Ni‐MOFs, enabling use non‐enzymatic sensing applications targeting UA.

Zr-based metalloporphyrin MOF probe for electrochemical detection of parathion-methyl

Biosensors and Bioelectronics, Journal Year: 2024, Volume and Issue: 261, P. 116515 - 116515

Published: June 20, 2024

An electrochemical (EC) sensor based on metalloporphyrin metal-organic framework (MOF) for the detection of parathion-methyl (PM) has been developed. The prepared MOF-525(Fe) exhibits great signal enhancement toward PM owing to its unique structural properties and activities. Under optimal experimental conditions, as-prepared EC exhibited excellent sensing performance with a wide linear range (0.1 μM-100 μM) low limit (LOD, 1.4 nM). Compared corresponding Fe (linker), superior sensitivity (28.31 μA cm
