“…Metals such as gold, 5,6 platinum, 7,8 palladium, 9,10 copper, 11,12 cobalt, 13,14 nickel 15, 16 and their metal alloys 17,18 have been widely investigated and exploited for non-enzymatic glucose sensing. It should be noted that noble metals and their alloys exhibit high catalytic activity towards glucose oxidation, but their high cost and low availability limit their large-scale application.…”

CuCo 2 O 4 nanowire arrays supported on carbon cloth (CuCo 2 O 4 NWAs/CC) were prepared via a simple hydrothermal synthesis and subsequent calcination process. As a 3D binder-free electrode for nonenzymatic glucose sensing, CuCo 2 O 4 NWAs/CC shows high sensing performance towards glucose under alkaline conditions, with a wide detection range from 1 mM to 0.93 mM, a low detection limit of 0.5 mM (S/N ¼ 3), and a high detection sensitivity of 3.93 mA mM À1 cm À2. Moreover, CuCo 2 O 4 NWAs/CC shows good selectivity in the presence of common interferents and good reproducibility for glucose detection, which make it a promising electrode material for sensitive determination of glucose in human samples.

“…Conductive polymers, such as polyaniline (PANI) are also being employed as semipermeable membranes to screen against the interfering species such as uric acid, ascorbic acid and acetaminophen. Ahammad et al employed gold nanoparticles adsorbed onto glassy carbon electrode modified with PANI [42] as the semipermeable membrane. Using electrochemical impedance spectroscopy technique, they were able to detect glucose concentrations from 0.3 mM to 10 mM with a detection limit of 0.1 mM.…”

Glucose biosensors have received significant attention in recent years due to the escalating mortality rate of diabetes mellitus. Although there is currently no cure for diabetes mellitus, individuals living with diabetes can lead a normal life by maintaining tight control of their blood glucose levels using glucose biosensors (e.g., glucometers). Current research in the field is focused on the optimization and improvement in the performance of glucose biosensors by employing a variety of glucose selective enzymes, mediators and semipermeable membranes to improve the electron transfer between the active center of the enzyme and the electrode substrate. Herein, we summarize the different semipermeable membranes used in the fabrication of the glucose biosensor, that result in improved biosensor sensitivity, selectivity, dynamic range, response time and stability.

“…In the trend of ultrasensitive detection, electrochemical methods are often used. The indicator-free DNA hybridization sensor based on graphene nanocomposite as the enhanced sensing platform for detection breakpoint cluster region gene and the cellular abl (BCR/ABL) [1] and non-enzymatic glassy carbon sensor modified with gold nanoparticles (GNPs) onto conductive polyaniline (PANI) for detection of glucose [2] can be given as examples. Electrochemical methods can be also adopted for the quantitative detection of medicament-diclofenac with the use of aptasensor based on bimetallic AgPt nanoparticledecorated carbon nanotubes [3] or to sensitive impedimetric determination of melamine with molecularly imprinted polymer-based electrode [4].…”

A capacitive sensor based on S-{12-[1-(pyridin-4-ylmethyl)-1H-1,2,3-triazol-4-yl]dodecyl} ethanethioate (FT), a compound with a functional group exhibiting selective affinity towards Cr(VI) ions, was developed. FT was mixed with shorter-chain thiol-decanethiol (DT), to obtain an Au electrode surface well covered by a thiol monolayer. The composition and high quality of self-assembled monolayers (SAMs) were crucial factors influencing the performance of the capacitive sensor. In this work, SAMs formed from FT and DT mixtures with different compositions were studied. For physicochemical characterization of SAMs X-ray photoelectron spectroscopy (XPS), contact angle measurements as well as atomic force microscopy (AFM) were used. Cyclic voltammetry was employed to estimate an electrode surface coverage. Based on the obtained results, the composition of thiol layer providing the best parameters for capacitive sensing of chromium(VI) was chosen. Moreover, the analytical performance of sensor was verified.
