“…As the electrode catalysts play a decisive role in glucose sensing performance, various materials have been employed to construct nonenzymatic glucose sensors. As reported noble metals such as Pt [7], Au [8], and Pd [9] display much higher activity for glucose oxidation. However, their further applications are limited by their rarity and high price.…”

Glucose detection is particularly important for clinical diagnosis and personal prevention and control. Herein, the smartphone-based amperometric glucose sensors were constructed using the NiS/CuS nanorods (NRs) as sensing electrodes. The NiS/CuS NRs were prepared through a facile hydrothermal process accompanied by the subsequent vulcanization treatment. The morphological and structural properties of NiS/CuS NRs were characterized with SEM, EDS, XRD, and XPS. Electrochemical measurements including cyclic voltammetry, chronoamperometry, and electrochemical impedance spectroscopy display that NiS/CuS NRs can act as highly efficient electrocatalyst for glucose detection. The NiS/CuS NRs electrodes present a wide detection range of 1–8000 μM for glucose sensing with the sensitivity of 956.38 μA·mM−1·cm−2. The detection limit was 0.35 μM (S/N=3). When employed in smartphone-based glucose sensing device, they also display a high sensitivity of 738.09 μA·mM−1·cm−2 and low detection limit of 1.67 μM. Moreover, the smartphone-based glucose sensing device also presents favorable feasibility in determination of glucose in serum samples with the recoveries ranging between 99.5 and 105.8%. The results may provide a promising viewpoint to design other new portable glucose sensors.

“…Glucose is one of the key molecules essential to the human body and is associated with energy and blood sugar levels. However, high concentrations can lead to diabetes, as well as complications such as kidney failure, blindness and stroke [200]. Zhao et al [201] proposed a flexible enzyme-free sweat glucose sensor based on coated carbon cloth, as shown in Figure 8a.…”

With the innovation of wearable technology and the rapid development of biosensors, wearable biosensors based on flexible textile materials have become a hot topic. Such textile-based wearable biosensors promote the development of health monitoring, motion detection and medical management, and they have become an important support tool for human healthcare monitoring. Textile-based wearable biosensors not only non-invasively monitor various physiological indicators of the human body in real time, but they also provide accurate feedback of individual health information. This review examines the recent research progress of fabric-based wearable biosensors. Moreover, materials, detection principles and fabrication methods for textile-based wearable biosensors are introduced. In addition, the applications of biosensors in monitoring vital signs and detecting body fluids are also presented. Finally, we also discuss several challenges faced by textile-based wearable biosensors and the direction of future development.

“…According to previous reports, increasing Au dispersion on the LDH can significantly enhance the detection sensitivity [ 59 , 60 ]. In addition, the size of gold nanoparticles also affects the detection results [ 8 ]. The Fe 3 O 4 @Au@CoFe-LDH glucose sensor shows good electrochemical response ( Figure 5 B).…”

“…Figure 1 illustrates the structure and mechanism of glucose sensor devices, which mainly contain four parts as follows: detection targets, sensitive device, transmission, and signal receiving system. Target molecules can be divided into two categories: invasive (blood [ 5 ]) and noninvasive (sweat [ 6 , 7 , 8 ], tear [ 9 ], saliva [ 10 ], and urine [ 11 ]). The traditional method of measuring glucose in blood by fingertip sampling not only brings psychological burden to patients, but also a cumbersome sampling process and strict operation.…”

Diabetes has become a chronic disease that necessitates timely and accurate detection. Among various detection methods, electrochemical glucose sensors have attracted much attention because of low cost, real-time detection, and simple and easy operation. Nonenzymatic biomimetic nanomaterials are the vital part in electrochemical glucose sensors. This review article summarizes the methods to enhance the glucose sensing performance of noble metal, transition metal oxides, and carbon-based materials and introduces biomimetic nanomaterials used in noninvasive glucose detection in sweat, tear, urine, and saliva. Based on these, this review provides the foundation for noninvasive determination of trace glucose for diabetic patients in the future.
