“…Moreover, to obtain the C dl (double layer capacitance), the voltammetry curves of Figure were used. Assuming that the charging of the electric double layer is solely responsible for the process, a linear behavior is obtained, and the angular coefficient gives the C dl . A linear relationship was obtained when the current was plotted against the scan rate variation, represented in Figure S3, Supporting Information.…”

Laser-induced graphene (LIG) has received great interest as a potential candidate for electronic and sensing applications. In the present study, we report the enhanced performance of a manganese carbonatedecorated LIG (MnCO 3 /LIG) composite electrode material employed for electrochemical glucose detection. Initially, the porous LIG was fabricated by directly lasing poly(ether sulfone) membrane substrate. Then, the MnCO 3 /LIG composite was synthesized via a hydrothermal method. Later, MnCO 3 /LIG was immobilized onto a glassy carbon electrode surface and employed for glucose detection. The structure of the MnCO 3 /LIG composite was carefully characterized. The influence of the MnCO 3 /LIG composite on the performance of the electrode was investigated using cyclic voltammetry curves. The MnCO 3 /LIG composite exhibited an excellent sensitivity of 2731.2 μA mM −1 cm −2 , and a limit of detection of 2.2 μM was obtained for the detection of glucose. Overall, the performance of the MnCO 3 /LIG composite was found to be superior to that of most of the MnCO 3 -based composites.

“…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.
