Abstract
Three types of silica hybrid nanomaterials, doped with silver, were studied for their antifungal effect against fungi Penicillium chrysogenum strain 2303. The hybrid nanomaterials based on SiO2 and cellulose ethers - hydroxypropyl cellulose, hydroxypropylmethyl cellulose and carboxymethyl cellulose, and silver were prepared by sol-gel method. The antifungal effect was quantified against P. chrysogenum 2303 based on the inhibition zone measurement by the agar diffusion test. The results showed that the hybrid nanomaterials containing hydroxypropylmethyl cellulose, doped with the highest silver concentration of 2.5 mass % Ag, have the most prominent antifungal effect towards the fungi in comparison to the other nanomaterials.
