Nanocomposite fibres for medical applications

Fibrous nanocomposites based on natural polysaccharides originated from algas were produced. Nanocomposite fibres were obtained by a wet method. Two kinds of ceramic nanofillers were applied i.e., nanometric amorphous silica (nSiO2) and natural hydroxyapatite (HAp). The presence of the nanofillers in a biopolymer matrix was determined using point X-ray microanalysis (SEM/EDS). FT-IR studies and Raman spectroscopy revealed that the presence of the nanofillers effected structure of the biopolymer chain, and structural changes depended on the introduced modifier type. Stronger effects were observed in case of material containing HAp as the nanofiller.
