“…We have worked out the sensitivity of synthesized sample S1 and it even reached up to surprising 10 490.45 (µA m m −1 cm −2 ). All above results exhibit that the glucose sensor based on sample S1 has the characteristics of the highest sensitivity and as‐assembled sensor is much higher than that of many noble metal‐based and Cu‐based electrocatalysis . Above excellent electrocatalytic performances of sample S1 may thanks to the oxygen vacancies which can increase the rate that electron reaches to the surface to increase reaction probability as trapping centers.…”

Porous CuO particles with oxygen vacancies are first synthetized by a simple calcination of Cu 2 C 2 O 4 particles. Oxygen vacancies are confirmed by high resolution transmission electron microscopy, electron paramagnetic resonance measurements, and X-ray photoelectron spectroscopy. When porous CuO particles with oxygen vacancies are as-assembled as nonenzymatic glucose sensors, they reveal high sensitivity and good anti-interference ability. The existing oxygen vacancies can help to increase the rate that electron reaches to the surface and accelerate the kinetics of the surface redox reactions to enhance the electrochemical performances of materials. In this work, the response time of porous CuO particles with oxygen vacancies' modified electrode for the electrocatalysis reaction is less than 3 s. Meanwhile, the calibration plot is linear over the wide concentration range of 0.5 × 10 −6 -6.32 × 10 -3 m and a detection limit of 50 × 10 -9 m. The developed sensor displays high sensitivity of 10 490.45 µA mm -1 cm -2 and good antiinterference ability, which is prior than many previous noble metal-based and Cu-based electrocatalysts.

A novel, highly stable, selective, and sensitive non‐enzymatic glucose sensor was developed by simple and effective modification procedure. The modification of gold microelectrodes by electrochemically deposited gold nanoparticles resulted in increase of surface area up to 37 %. The nanostructured surfaces of the gold microelectrodes obtained by different modifications were studied by confocal microscopy, atomic force microscopy, and scanning electron microscopy. The gold nanoclusters exhibit great electrocatalytic properties toward glucose with a wide linear range from 0.5 to 50 mM, with a limit of detection 218 μM, and sensitivity of 185.2 mA mM−1cm−2. Moreover, the modified microelectrodes display good reproducibility, stability, and selectivity in the presence of poisoning compounds. Due to the small dimensions of gold microelectrodes and a very small volume of the sample, the microelectrodes make a contribution to miniaturisation of the system.

Nanostructured materials can now be engineered with great precision and complexity as a result of advances in design and fabrication, and offer distinct advantages in many biosensing and biomedical applications. The materials most widely used in this field are semiconductors and noble metals. Each offers multiple length scales of nanostructuring that program their physicochemical properties for different biosensing applications. Here, nanostructured materials and their applications are reviewed together with semiconductors and noble metals, as well as hybrid materials that unite these two classes—all with the goal of linking performance characteristics to applications in biomedicine.
