On the Biological Activity of a Gold-Containing Nanocomposite Based on Sulfated Carrageenan Polysaccharide
Abstract
The results of the synthesis of a biologically active nanostructured polymer system based on natural κ-carrageenan polysaccharide, which simultaneously acts as a reducing and stabilizing agent for emerging gold nanoparticles, are presented. The structure and nanomorphological characteristics of the resulting nanocomposite (in particular, in an aqueous solution), represented by κ-carrageenan stabilized Au0 nanoparticles, the size of which varies in the range of 6–20 nm, are established using modern spectral (infrared and optical spectroscopy, dynamic light scattering) and microscopic (transmission electron microscopy) methods. It is for the first time established that the Au0NP/κ-CG-DP nanocomposite has pronounced anticoagulant activity, affecting the intrinsic and extrinsic blood-coagulation pathways.
