“…4 Since the discovery of DA in the 1950s, the determination of DA has become very important in biomedical and biological analysis research studies and has received great attention from neuroscientists and chemists. 5 Especially, the change in the DA concentration in biological samples is an important indicator of possible physical abnormalities or diseases. Thus, the accurate detection of DA is of great significance for the clinical diagnosis of some diseases.…”

In this study, a novel Ni-BTC@Ni3S4 composite was fabricated by solvothermal reaction using an in situ etching vulcanization strategy and characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM), X-ray photoelectron spectroscopy (XPS), electron paramagnetic resonance (EPR), and Brunauer–Emmett–Teller (BET) analyses. The existence of a sulfur vacancy and Ni3+ in the as-prepared vein-like Ni-BTC@Ni3S4 greatly promoted the electrochemical sensing activity of the materials. Herein, a simple electrochemical sensor (Ni-BTC@Ni3S4/CPE) has been fabricated and used for the detection of dopamine (DA). The current signal of the Ni-BTC@Ni3S4/CPE-modified electrode was linear with the concentration of DA in the range of 0.05–750 μM (R 2 = 0.9995) with a sensitivity of 560.27 μA·mM–1·cm–2 and a detection limit of 0.016 μM. At the same time, the sensor has good stability and anti-interference ability. This study could provide a new idea and strategy for the structural regulation of composite electrode-modified materials and sensitive sensing detection of small biological molecules.

Development of hybrid nanozymes with high catalytic efficiency is of critical importance for enzyme mimics in biological catalytic fields. Herein, we reported a polydopamine (PDA) surface modification-assisted pyrolysis strategy for preparing CoO nanoparticles/N-doped carbon sheets/reduced graphene oxide composites (CoO/N-CS-rGO). In this strategy, PDA with abundant amines and imines could serve as an eco-friendly N-contained precursor and a connecting agent between GO matrix and CoO. Due to the superior conductivity of N-CS-rGO, synergistic catalysis between CoO nanoparticles (NPs) and N-CS-rGO, and intrinsic oxidase-like characteristic, the CoO/N-CS-rGO was used as an ultrasensitive signal amplification platform for simultaneously analyzing dopamine (DA) and uric acid (UA) in a neutral solution. Significantly, the fabricated electrochemical sensor showed ultrahigh sensitivities of 1378 μA mM–1 for DA and 1393 μA mM–1 for UA. The linear range of 0.5–110 μM for DA and 1–125 μM for UA could be obtained by this sensor. Furthermore, the stability and selectivity of the CoO/N-CS-rGO-based hybrid biosensor were evaluated. The results showed that the biosensor performed good stability and brilliant selectivity against interfering analytes. Also, the CoO/N-CS-rGO/GCE was adopted to monitor two analytes in human serum samples with high accuracy. This work provides an efficient PDA-assisted synthetic strategy to prepare hybrid nanomaterials and shows broad prospects for biosensing, biotechnology, and clinical diagnosis.

In the present work, exfoliated graphite oxide (E-GO) was prepared by sonicating graphite oxide (GO) (prepared by modified Hummer’s and Offemam methods). Prepared GO and E-GO were characterized using infrared absorption spectroscopy, X-ray diffraction, and scanning electron microscopy. The electrocatalytic properties of GO and E-GO towards detection of dopamine (DA), uric acid (UA), and folic acid (FA) were investigated using cyclic voltammetry and differential pulse voltammetry. Our results revealed that E-GO has a slighter advantage over the GO as an electrode modifier for detection DA, UA, and FA, which might be ascribed to the good conductivity of E-GO when compared to the GO.
