ABSTRACT

Single-walled carbon nanotubes (SWCNTs) form complexes with amylose, amylopectin and other polysaccharides provided the latter are non-ionic as proven by Raman spectroscopy, rheological and thermal (TG/DTG and DSC) studies. Numerical simulations carried out for SWCNTs with dextrans proved that enveloping polysaccharide chains around SWCNTs is not crucial for the complex formation. ZnS and CdS quantum dots could be generated inside sodium hyaluronate or potato starch gels and they did not agglomerate on evaporation of the gels to dryness. There were no recognizable interactions between quantum dots and polysaccharide matrix. On generation of CdS quantum dots in potato starch gels, formation of polysaccharide nanotubes was observed. Such nanotubes included CdS quantum dots. Potato starch gels provided a suitable matrix hindering nanosilver and nanogold particles from agglomeration.

Keywords: carbon nanotubes, polysaccharide nanotubes, quantum dots
