摘要：
Water-soluble nanobiocomposite CdSe quantum dots were obtained using the stabilizing potential of natural biologically active polysaccharides galactomannan and κ-carrageenan. A complex of physicochemical methods was used to investigate the biphasic amorphous-crystalline structure of the obtained nanocomposites, the size range (4.8—6.9 nm) of the formed CdSe particles was determined, and, additionally, it was shown that aqueous solutions of the nanocomposites in question were characterized by the presence of photoluminescence in two spectral regions, namely, 410—450 and 510—580 nm.
