Humic-based bionanocomposites containing stable paramagnetic gold nanoparticles for prospective use in pharmaceuticals

Structural peculiarities and supramolecular organization of medicinally promising nanocomposites, synthesized from humic substances, which essentially differ depending on decomposition degree, have been studied using electron spin resonance, transmission electron, and confocal laser scanning microscopy techniques and some other modern physical–chemical methods. It is shown that stable zero-valent gold nanoparticle of about 10–17?nm in size are formed in a natural macromolecular matrix. The nanocomposites obtained turn out to be stable in aggregative state for a long time and preserve their properties that are extremely important for prospective medicinal substances.     

Synthesis of Selenium-Containing Humic Nano-Biocomposites from Sodium Bis(2-phenylethyl)phosphinodiselenoate

New water-soluble selenium-containing nano-biocomposites have been synthesized by oxidation of sodium bis(2-phenylethyl)phosphinodiselenoate with hydrogen peroxide using humic substances to stabilize selenium nanoparticles. As shown by a set of physicochemical methods, the obtained hybrid nanocomposites are formed as spherical hexagonal selenium particles with a size of 13–30 nm, dispersed in a humic matrix.
