“…The experiments performed by Sun suggested that the synergistic effect of V2O5/Carbon nanotubes leads to increased amount of single-stranded DNA being adsorbed onto the electrode's surface, thus increasing the electrochemical response. The biosensor produced by Sun et al was able to detect concentrations in the range of 1.0  10 -11 to 1.0  10 -6 mol L -1 , with detection limit of 1.76  10 -12 mol L -1 .Another biosensor based on these types of nanocomposites electrodes was reported by Alagappan et al[594] for detection of methylglyoxal, which is responsible for complications in diabetic patients. This bioelectrode was able to measure concentrations of methyglyxal in par-boiled rice ranging from 0.1 to 100 µM, with sensitivity of 1130.86 µA cm -2 , limit of detection of 2 nM and response time <18 s.Vanadium oxide has an isoelectric point of 3 which allows electrostatic attraction of the glutathione cofactor, that has a high isoelectric point(5.93).…”

In the absence of methyglyxal, glutathione will oxidize to hemithioacetal at -2.74 mV, while in the presence of 0.1 µM of methyglyxal the the required potential is -32.29 mV[594].…”

Human health, environmental protection and safety are just a few examples of current humankind main concerns, that drive the scientific community to develop sensors able to precisely monitor and alert to possible harms in real time. Over the years, semiconductor metal oxide-based materials have been largely employed as sensors dedicated to several applications, being particularly interesting at the nanometer scale, since it is largely known that smaller crystallite size enhances sensor's performance. Moreover, these materials are highly appealing as they can be produced by low-cost wet-chemical synthesis routes and are in general nontoxic, earth abundant and low-cost. This manuscript extensively reviews the recent developments of nanostructured semiconductor metal oxide sensors ranging from gas to humidity sensors, including ultraviolet (UV) sensors and biosensors. Zinc oxide (ZnO), titanium dioxide (TiO2), tungsten trioxide (WO3), copper oxide (CuO and Cu2O), tin oxide (SnO and SnO2), and vanadium oxide (VO2, V2O5)-based sensors either as nanoparticles or as continuous films/layers are described. Their sensing properties are correlated to size, shape, presence of defects, doping elements, amongst other relevant parameters. Different techniques and methods of fabricating these materials are addressed. The review is concluded with novel approaches for functionalization and future perspectives for sensor developments.

“…Similar to the sensor, a biossensor turn an analytical response into a measurable chemical signal and detects only a certain biological product as a target analyte. The use of different structures of V 2 O 5 as sensitive component in biosensor device has been explored in several target analyte such as urea, glucose, gene sequence, EGFET-biosensor, methylglyoxal in rice and among others [48][49][50][51][52][53].…”

The first synthesis of pentoxide vanadium (V2O5) as gel completed 135 years in 2020. Since its first synthesis, the V2O5 has attracted attention over the years in different areas in science and technology. There are several possibilities to obtain V2O5 resulting in different structures. Among these methods, it is possible to mention the sol–gel, hydrothermal/solvothermal synthesis, electrospinning, chemical vapor deposition (CVD), physical vapor deposition (PVD), template-based methods, reverse micelle techniques, Pechini method and electrochemical deposition that can be considered as the great asset for its varied structures and properties. Progress towards obtaining of different structures of V2O5, and phases have been resulted in lamellar structure with wide interlayer spacing, good chemical and thermal stability and thermoelectric and electrochromic properties. Throughout this advancement, its performance for industrial applications have made a strong candidate in electrochromic devices, photovoltaic cell, reversible cathode materials for Li batteries, supercapacitor, among others. This chapter will be to assist an updated review since the first synthesis up to current development.
