Abstract

Pierwszym przedmiotem zgłoszenia jest sposób otrzymywania kompozytu na bazie chitozanu, obejmujący etap biotechnologicznego przygotowania aktywnego barwnika, etap przygotowania nanocząstek metalicznych, wytworzenie ciekłego nanokompozytu, charakteryzujący się tym, że do 30 cm<sup>3</sup> roztworu chitozanu o stężeniu 2% (w/v) dodaje się aktywny barwnik, który stanowi piomelanina, do końcowego stężenia 200 µg/cm<sup>3</sup> i 3 cm<sup>3</sup> koloidalnego roztworu nanocząstek srebra o stężeniu 400 µg/cm<sup>3</sup>, opcjonalnie do mieszaniny dodaje się hydroksyapatyt w ilości 1% wagowego względem objętości mieszaniny i miesza się w temperaturze pokojowej, aż do uzyskania jednorodnej zawiesiny. Zgłoszenie obejmuje również nanokompozyt otrzymany sposobem oraz zastosowanie kompozytu.
