“…The band at 482 cm À1 could be assigned to C-H bending, while the band from 2845 to 3022 cm À1 could be referred to C-H stretching, [32][33][34] and the band located at 3438 to 3700 cm À1 is referred to OH vibrations. 33 On the other hand, SV showed different bands at 730, 859, and 924 cm À1 , which could be assigned to V-O-V stretching vibrations, respectively, 37,38 VO 3À group antisymmetric vibrations, and V-O-Ag vibrations, [39][40][41] and VO 3 symmetric stretching vibrations, respectively. 41 Furthermore, the spectral regions between 3750-2750 and 2030-1200 cm À1 (highlighted in blue) are associated with the stretching and bending vibrations of physisorbed water molecules and surface hydroxyl groups.…”

The fast advancements in technology have generated significant interest in optoelectronic materials. Nevertheless, the difficulty of creating affordable materials with exceptional optical characteristics is an ongoing challenge. Therefore, the objective of this work was to tune the optical properties of poly(methyl methacrylate) (PMMA) by embedding silver vanadate (SV) in the polymer matrix. Moreover, the wettability test of the fabricated composite membranes showed a hydrophobic behavior, with the PMMA film containing 0.6 wt.% SV showed a contact angle of 86.75 ± 0.7°. Furthermore, SV showed high thermal stability with a maximum weight loss of 0.74% at 830°C, which is very high thermal stability at high temperatures. In addition, the 0.6 wt.% SV@PMMA film exhibited a maximum weight loss of 96.7% at 785°C. Moreover, the 0.6 wt.% SV@PMMA film showed the lowest indirect band gap energy (2.02 eV) compared to the other films and pure SV NPs. The findings demonstrate the potential of the synthesized films for optoelectronic applications.

“…The magnitude of the impact of complex matrices on the analytical signal in the presence and absence of antifouling molecules deposited on the sensor surface significantly affects the performance, and the limit of detection of the biosensor is an important aspect that needs consideration. , Earlier, Mandal et al − had reported the shape size, aggregation, hydration conformations, hydrogen bonding, and thermodynamic characteristics on collagen (fibrous protein) in acetic acid/acetate buffer, BSA (globular protein) in aqueous, and some peptide micelles in aqueous and nonaqueous environments. The interactions of various surfactants with the above-mentioned biomaterials have also been reported by the same authors.…”

The current study describes a simple method to fabricate soy protein-based nano-biocomposites (NBCs) impregnated with sago starch-capped copper oxide nanorods (CuO NRs), for electrochemical detection of cytosine, which is useful for de novo drug formulations in pharmaceutics. The physicochemical properties of the NBCs were studied in detail and might be useful for biomedical applications. CuO NRs of sizes of 18.1–22.7 nm were synthesized by varying the concentrations of sago starch (0.5–5 μM) and characterized using various analytical techniques. Sago starch acts as both a reducing agent and stabilizer. The NRs show better optical properties (increased band gap E g = 3.01 eV), which could find potential applications in the photovoltaic cells. The sago-capped CuO NRs were impregnated in soy protein (1:1 ratio), and the physicochemical properties of the fabricated nanobiocomposites (NBCs) were studied. Differential scanning calorimetry (DSC)/thermogravimetric analysis (TGA) was employed to determine the thermodynamic parameters, and the results indicate enhanced thermal stability of the NBCs. Moreover, increased water uptake of the NBCs demonstrates the biodegradability of the prepared NBCs that can find use in tissue engineering applications. This CuO-SG-SY/GCE can be used for the detection and quantification of cytosine in real-sample analysis. Thus, soy protein NBCs incorporated with sago starch-capped CuO NRs provide a simple and facile route, which is ecofriendly and cost-effective and has both industrial and pharmaceutical applications.

The proposed study describes a novel and disposable voltammetric sensor that designed for the sensitive determination of celestine blue (CelsB) using a pencil graphite electrode (PGE). The electrochemical characterization study of the designed sensor was performed by recording the cyclic voltammograms (CVs) and electrochemical impedance (EI) curves in 5.0 mM of Fe(CN)63-/4- including 0.10 M of KCl, and compared with the other carbon-based electrodes such as carbon paste (CPE) and glassy carbon (GCE) electrodes. The electrochemical behaviour of CelsB was examined at different carbon-based electrodes including PGE, CPE, and GCE by the cyclic voltammetric (CV) method. The recorded CVs showed that the remarkable response obtained at PGE toward oxidation of CelsB. Moreover, the PGE shows a wide linear range (4.0 − 150 μM) and detects the CelsB with a notable limit of detection (1.21 μM). In addition, the results from the interference studies proved that the PGE enables selective voltammetric determination of CelsB in presence of various species. A feasibility study for CelsB sensor was also tested on tap water and cherry apple juice samples and the recovery values obtained between 96.2 − 103 % with high precision and accuracy indicated that the PGE shows an acceptable and good applicability to real samples.
