  ABSTRACT: Facile and environmentally friendly method of the preparation of silver and gold nanoparticles embedded in potato starch matrix (Sp) was developed. UVVIS spectroscopy, transmission electron microscopy (TEM) and Fourier transform infrared (FTIR) spectra confirmed formation of ball shaped Ag and Au nanoparticles situated within the polysaccharide template. EDS spectra confirm presence of silver and gold nanocrystals in the obtained composites. Differential scanning calorimetry (DSC) showed that Sp/Au composite started to decompose earlier. The decomposition is slower and two-step, in contrast to Sp and Sp/Ag. NanoAg accelerates carbonization. Molecular weights of polysaccharide chains of the matrix were estimated with the size exclusion chromatography coupled with multiangle laser light scattering and refractometric detectors (HPSEC-MALLS-RI). Formation of nanosilver containing composites led to partial depolymerisation of polysaccharides from the amylose fraction. In the case of nanogold we observed depolymerisation of polysaccharide chains from both fractions.
