“…Over the past decades, detecting metabolite biomarkers have been achieved by mainly using laboratory-based technologies including chromatography [ [7] , [8] , [9] , [10] ], spectrophotometry [ [11] , [12] , [13] ], electrochemical analysis [ 14 , 15 ], titrimetric [ 16 ], chemiluminescence [ 17 , 18 ], resonance light scattering assays [ 19 ]. However, such laboratory-based methods are expensive since they usually require large instruments and professionally trained operators.…”

“…Chronic diabetes disease has been affecting a large number of people all around the world, thereby developing a noninvasive glucose detection technique with high sensitivity, and low cost is of substantial importance [1,2]. Several methods, such as colorimetry [3], gas or liquid chromatography [2,4], fluorescence [5], Fourier transform infrared spectroscopy [6], chem-or electrochemiluminescence [7,8], and electrochemical techniques [9], have been employed to determine the glucose level in human serum and foodstuffs during the last few decades. However, there are some shortcomings of glucose determination by reported methods.…”

A novel molecularly imprinted electrochemical biosensor for glucose detection is reported based on a hierarchical N-rich carbon conductive-coated TNO structure (TNO@NC). Firstly, TNO@NC was fabricated by a novel polypyrrole-chemical vapor deposition (PPy-CVD) method with minimal waste generation. Afterward, the electrode modification with TNO@ NC was performed by dropping TNO@NC particles on glassy carbon electrode surfaces by infrared heat lamp. Finally, the glucose-imprinted electrochemical biosensor was developed in presence of 75.0 mM pyrrole and 25.0 mM glucose in a potential range from + 0.20 to + 1.20 V versus Ag/AgCl via cyclic voltammetry (CV). The physicochemical and electrochemical characterizations of the fabricated molecularly imprinted biosensor was conducted by transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD) method, X-ray photoelectron spectroscopy (XPS), electrochemical impedance spectroscopy (EIS), and CV techniques. The findings demonstrated that selective, sensitive, and stable electrochemical signals were proportional to different glucose concentrations, and the sensitivity of molecularly imprinted electrochemical biosensor for glucose detection was estimated to be 18.93 μA μM −1 cm −2 (R 2 = 0.99) at + 0.30 V with the limit of detection (LOD) of 1.0 × 10 −6 M. Hence, it can be speculated that the fabricated glucose-imprinted biosensor may be used in a multitude of areas, including public health and food quality.

“…Therefore, the detection of glucose is of great significance to human health. Over the past few decades, many techniques have been used to detect glucose in human blood, such as colorimetry ( Liu et al, 2011 ), gas chromatography ( Larsen, 2015 ), fluorescence ( Xie et al, 2017 ), and electrochemical sensors ( Lpa et al, 2019 ; Xu et al, 2021 ). Among them, the accuracy of colorimetry is poor, the gas chromatography equipment is complex and expensive ( Feng et al, 2016 ; Hui and Ying, 2017 ; Wang et al, 2020 ), and the fluorescence is very sensitive to some interfering substances ( Zheng et al, 2019 ).…”

A non-enzymatic electrochemical sensor for glucose detection is executed by using a conductive metal–organic framework (MOF) Cu-MOF, which is built from the 2,3,6,7,10,11-hexahydroxytriphenylene (HHTP) ligand and copper acetate by hydrothermal reaction. The Cu-MOF demonstrates superior electrocatalytic activity for glucose oxidation under alkaline pH conditions. As an excellent non-enzymatic sensor, the Cu-MOF grown on Cu foam (Cu-MOF/CF) displays an ultra-low detection limit of 0.076 μM through a wide concentration range (0.001–0.95 mM) and a strong sensitivity of 30,030 mA μM−1 cm−2. Overall, the Cu-MOF/CF exhibits a low detection limit, high selectivity, excellent stability, fast response time, and good practical application feasibility for glucose detection and can promote the development of MOF materials in the field of electrochemical sensors.
