“…The slope was close to the theoretical value of 0.0591/2. Therefore, the ratio of the electron transfer number to the proton transfer coefficient in the redox process was about 2 : 1 . Protons participated in the electrocatalytic reaction of the CLE on the modified GCEs.…”

“…Clenbuterol hydrochloride (4-amino-3,5-dichloro-a-tert butyl aminomethyl benzyl alcohol hydrochloride; CLE) is a typical β-receptor agonist [1,2] that promotes protein synthesis and accelerates growth in animals [3]. Studies have shown that CLE can harm humans by entering the human body through the food chain if it remains in livestock products [4,5].…”

“…Enzyme-based methods have been used to improve the performance of CLE sensors [10][11][12]; However, enzymes are sensitive to reaction conditions, which restricts their application. Enzyme-free amplification methods have shown great potential in CLE detection [3,13,14]. The excellent catalytic performances of nanomaterials have been studied to improve the sensitivity of the CLE sensors [1,4,15,16].…”

We describe a novel enzyme-free sensor for clenbuterol (CLE) prepared by a simple electrochemical method. A new method to detect clenbuterol hydrochloride was developed by single-walled carbon nanotubes (SWCNTs) arrays and gold nanoparticles (AuNPs)-Cl À complex. SWCNT arrays modified glass carbon electrode (GCE) was first prepared by one-pot method with cyclic voltammetry.Then AuNPs were deposited on the SWCNT arrays and complexed with a high concentration of chloride ions (0.1 mol/L). The asfabricated SWCNT arrays/AuNPs senor have showed an excellent sensitivity in CLE detection with lower detection limit (0.5 ng/L) and wider linear range (1-800 ng/L). Its high performance can be attributed to the high catalytic activity of SWCNT arrays and the special absorption of CLE on AuNPs. The surface morphology of the electrode was analyzed by atomic force microscopy, X-ray photoelectron spectroscopy and SEM. This work offers a new method for the synthesis of SWCNT arrays and a novel avenue for CLE detection. The modified electrode was stable with 98.5 % of its initial current response after remained one month, it was used to detect CLE in human urine, animal tissues and food with satisfactory results.

The fast detection of 5‐hydroxymethyl‐2‐furfural (HMF) in food industry is vital because of its toxicity and mutagenicity. A glassy carbon electrode (GCE) modified with black phosphorene (BP) nanosheets was prepared and coated with Nafion to improve stability. The electrode has excellent electrochemical stability and current response for HMF electroreduction. The good linear relationship is in the concentration range of 0.1–10 μg/mL with the detection limit of 0.012 μg/mL. HMF electroreduction is a diffusion‐controlled process involving two electrons and two protons. The sensor was successfully applied to the measurement of HMF in milk with the recovery values of 92.92 %–96.33 %.
