“…The relationship of E pa and the pH was well-fitted to the linear function of E pa = −0.053 pH + 0.553 ( R 2 = 0.994). The experimental slope value (0.053 V/pH) was roughly equivalent to the one of the Nernst equation (0.059 V/pH), manifesting that the electrocatalytic oxidation of MSZ on the NiS/Ni 3 S 4 /NSC/GCE sensor required an equal number of protons and electrons. , …”

“…The experimental slope value (0.053 V/ pH) was roughly equivalent to the one of the Nernst equation (0.059 V/pH), manifesting that the electrocatalytic oxidation of MSZ on the NiS/Ni 3 S 4 /NSC/GCE sensor required an equal number of protons and electrons. 4,55 The kinetic behaviors of MSZ (100 μM) on the NiS/Ni 3 S 4 / NSC/GCE were investigated by CV at various scanning speeds (v = 40−500 mV s −1 ). As illustrated in Figure 5c, both anode (I pa ) and cathode peak currents (I pc ) for MSZ on NiS/Ni 3 S 4 / NSC gradually increased with the increase of the scan rates.…”

Herein, a metal−organic framework-derived NiS/ Ni 3 S 4 heterostructure embedded in N, S co-doped carbon (NiS/ Ni 3 S 4 /NSC) was successfully prepared and applied in electrochemical detection of anti-inflammatory drug mesalazine (MSZ). The exposed sulfur atoms of the NiS/Ni 3 S 4 /NSC composite could efficiently recognize and trap MSZ targets through the S−π interaction. Meanwhile, the active metal centers of NiS/Ni 3 S 4 / NSC revealed a high-performance catalytic property for the oxidation of MSZ on the working electrode surface. The highly efficient adsorption and electrocatalytic abilities of the NiS/Ni 3 S 4 / NSC composite enhanced the electrochemical signals for MSZ detection. Markedly, the glassy carbon electrode modified by NiS/ Ni 3 S 4 /NSC (NiS/Ni 3 S 4 /NSC/GCE) featured a low limit of detection (LOD, 4.4 nM) for the electrochemical analysis of MSZ in the 0.05−100 μM concentration range. Moreover, the sensor could avoid the interference of the coexisting species during detection of MSZ and also revealed satisfactory reproducibility, repeatability, and stability. Particularly, the NiS/Ni 3 S 4 /NSC/GCE sensor was used to monitor the contents of MSZ in practical drug, human serum, and urine samples with satisfactory recoveries. The remarkable performance demonstrated that the NiS/Ni 3 S 4 /NSC/ GCE sensor could be a prospective candidate for the accurate detection of MSZ in the biomedical fields.

“…Polypyrrole is a conductive organic polymer widely used in developing electrochemical sensors [11,12] due to present branching functional groups, such as carboxylic acid groups, which can facilitate anchoring other species, such as enzymes, onto the hybrid material surface. Laccase is an enzyme widely employed to develop electrochemical biosensors due to its excellent electrocatalytic properties toward phenolic compounds [13][14][15].…”

An electrochemical biosensor for the bisphenol A determination was constructed onto a glassy carbon electrode modified with a hybrid nanostructure based on polypyrrole‐3‐carboxylic acid/Sb2O5/reduced graphene oxide and laccase enzyme. The hybrid nanostructure was characterized by X‐ray photoelectron spectroscopy (XPS), HR‐TEM, SEM microscopy, and electrochemical techniques. The biosensor displayed excellent response for bisphenol A determinations by differential pulse voltammetry, showing a theoretical detection limit of 9.9 nmol L−1 in the linear range of 0.1–1.0 μmol L−1. The biosensor demonstrated excellent selectivity in the determinations of bisphenol A in tap water without significant interference from other species, such as 17β‐estradiol, Estriol, Progesterone, Catechol, Hydroquinone, Ascorbic acid, and Dopamine. The biosensor also has presented an excellent performance in bisphenol A determinations in water, with recovery tax ranging from 99.6 to 101 %. Therefore, it can be used satisfactorily to detect bisphenol A in real samples.
