Enhancing colloidal stability of nanodiamond via surface modification with dendritic molecules for optical sensing in physiological environments.

Pre-treatment of diamond surface in low-temperature plasma for oxygenation and in acids for carboxylation was hypothesized to promote the branching density of the hyperbranched glycidol polymer. This was expected to increase the homogeneity of the branching level and suppress interactions with proteins. As a result, composite nanodiamonds with reduced hydrodynamic diameters that are maintained in physiological environments were anticipated.

Tailoring Physicochemical Properties of VO Nanostructures: Influence of Solvent Type in Sol-Gel Synthesis.

The influence of different solvents, including aqueous and nonaqueous types, on the physicochemical properties of VO nanostructures was thoroughly investigated. Various characterization techniques, such as XRD, XPS, FTIR, Raman spectroscopy, UV-vis DRS, SEM, TEM, and BET, were employed to analyze the obtained materials. Additionally, the adsorption properties of the synthesized VO nanostructures for methylene blue were examined, and kinetic parameters of adsorption were calculated.
