A novel and ultrasensitive electrochemical biosensor based on MnO2-V2O5 nanorods for the detection of the antiplatelet prodrug agent Cilostazol in pharmaceutical formulations

Binder-free Mn–V–Sn oxyhydroxide decorated with metallic Sn as an earth-abundant supercapattery electrode for intensified energy storage

“…Upon deconvolution, no extra peaks were observed, indicating the predominance of one valence state of vanadium (V 4+ ). [66][67][68][69][70] The Sn 3d spectrum showed two asymmetric peaks at 497 and 486.6 eV that correspond to Sn 3d 5/2 and Sn 3d 3/2 , respectively. 33,71,72 The deconvolution of these peaks revealed four extra peaks.…”

Development of Electro-Reduced AgNPs/MnO2/rGO Composite toward a Robust Sensor for the Simultaneous Determination of Piroxicam and Ofloxacin

“…29 Nevertheless, the poor interfacial contact, retarding the charge transfer, limits the utilization of MnO 2 -derived materials for the electrochemical determination of antibiotic species. 30 Consequently, the preparation of high-performance MnO 2based electrodes, which can sensitively detect PRX and OFX antibiotics, has remained an unanswered problem.…”

“…Thus, structural diversity and various chemical oxidation states of Mn, which are able to promote redox reactions, has featured MnO 2 material as a potential candidate for electrochemical analysis . Nevertheless, the poor interfacial contact, retarding the charge transfer, limits the utilization of MnO 2 -derived materials for the electrochemical determination of antibiotic species . Consequently, the preparation of high-performance MnO 2 -based electrodes, which can sensitively detect PRX and OFX antibiotics, has remained an unanswered problem.…”

Sensitive Determination of SARS-COV-2 and the Anti-hepatitis C Virus Agent Velpatasvir Enabled by Novel Metal–Organic Frameworks

“…However, the determination range is somewhat expensive and time-consuming. In this regard, electrochemistry can provide highly sensitive and rapid analysis techniques that are simple and cost-effective. − The electrochemical determination of VLP using the molecular-imprinted polymer deposited on a 3D starfish-like hollow nickel skeleton decorated with the MWCNT–Au NP-modified glassy carbon electrode has recently been reported in pharmaceutical formula and biological fluids . Despite the achieved good linearity (5.66–90.60 nM) and low limit of detection (LOD) (0.227 nM), the high cost of the composite and the tedious synthesis method render the whole process hard to adopt for routine analysis .…”
