Metal-free, cost-efficient, redox-active electrode materials, combining graphene derivatives with nitrogen-rich polymelamine (PM), are widely explored as an interface layer for electrocatalysis and an electrochemical sensor platform. However, conventional chemical routes often yield derivatives of PM suffering from impaired redox behavior, restricting their electron-transfer kinetics. Herein, an optimal potentiodynamic method has been established to electrodeposit PM on electrochemically reduced graphene oxide (ErGO). A supporting electrolyte, containing Cl-, enhances the formation of intermediates NH3+ and ═NH2+ at the monomeric melamine, eventually interacting with the residual oxygenated functional groups of ErGO to form PM. In situ Raman spectrum analysis revealed the influence of the defective area and the graphitization ratio on the ErGO surface during the course of electropolymerization of melamine. Under optimal electrodeposition conditions (E = 0-1.6 V; ν = 0.1 V/s), the amount of electrodeposited PM on the ErGO surface was determined to be 16.5 μg/(cycle·cm2), using electrochemical quartz crystal microbalance analysis. An ErGO-PM-modified glassy carbon electrode (GCE) and a screen-printed electrode exhibit the direct electrooxidation of acyclovir (ACV). Amperometric analyses of ErGO-PM-modified electrodes exhibited the lowest detection limit of 137.4 pM with analytical robustness, rapid steady state, and reproducibility promising for ACV detection in complex biological matrices.

Abstract Tin (Sn2+) ions incorporated hydroxyapatite (HAp) nanospheres are prepared by wet chemical. The Sn2+ ions lead to reduce crystallite size with modified vibration groups. The nanosphere is achieved on incorporation. The surface area and pore diameter are enhanced at low Sn2+ ions (11.29%). The specific capacitance (231 F g-1 at 3 mAg−1) (230%) is augmented at higher incorporation (27.27%) compared to pristine. The 100% cyclic stability up to 800 cycles is achieved. Here, the correlated partial amorphization, atomic disorder and surface properties are realized. Thus, the tin-calcium phosphate demonstrates an outstanding candidate for electrochemical energy storage application.

Hybrid nanomaterials with inherent physicochemical properties and cytocompatibility are beneficial for healthcare utilities. This paper demonstrates the hybridization of transition-metal oxide (molybdenum trioxide, MoO3), optoelectrochemically active dye complex (Ru(II)), and biopolymer (chitosan, CS) into a single nanosystem. The asafetida-resin-mediated green synthesis of MoO3 nanoparticles (g-MoO3 NPs) enabled chemical adsorption of Ru(II) and CS. Optical imaging functionality of pristine g-MoO3, g-MoO3-Ru(II), and g-MoO3-Ru(II)/CS has been evaluated using Caenorhabditis elegans, as an in vivo animal model, at an excitation wavelength of 450 nm and observed emission of ∼600 nm. The localization of chitosan on the surface of g-MoO3-Ru(II) exhibits cytocompatibility promising for intracellular imaging. The intracellular antioxidant properties of the g-MoO3-Ru(II)/CS nanocomposite are more profound than pristine NPs as assessed by measuring reactive oxygen species and protein carbonyls against the standard drug resveratrol. The electrochemical transducing ability of the hybrid g-MoO3-Ru(II) nanocomposite has been tested using butein, as a model herbaceutical, with nanomolar precision (50-1250 nM). The triad composite of metal oxide, dye, and biopolymer enabled synergistic properties that are suitable for multifunctional application in intracellular imaging, antioxidant, and electrochemical sensor studies.
