Dopamine is an essential neurotransmitter for daily cognitive functions controlling many neurophysiological processes including memory, cognition, and physical control. Development of analytical methods sensors to detect dopamine important health monitoring neurological research. This review provides overview recent advances in the development electrochemical catalytic biosensors based on enzyme enzyme-mimetic materials discusses their potential applications measurements biological fluids. The first part summarizes critically assesses different types enzymes mimetic that can be used catalytically convert dopamine, followed by a discussion biosensor’s fabrication, key design parameters, detection mechanism various electrode platforms ranging from single-use screen-printed electrodes microneedles implantable microelectrodes. second examples samples, saliva, urine, serum, cell cultures, brain tissue. We conclude with summary advantages limitations these devices clinical field, outlook future research towards implementation broader adoption neurophysiology, pharmacology, field.

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

Applied Organometallic Chemistry, Год журнала: 2024, Номер 38(4)

Опубликована: Янв. 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, Год журнала: 2024, Номер 261, С. 116515 - 116515

Опубликована: Июнь 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
