Biosyntéza nanočástic ušlechtilých kovů

Abstract

This thesis focuses on the biosynthesis of noble metals nanoparticles, on their practical aspects, biosynthesis mechanisms and factors that affect them. Isolation and resulting immobilization of biosynthesised nanoparticles is discussed. Different biosynthesis studies are evaluated and sorted depending on the type of used biomass. The aim of the practical part of the thesis was to perform the pilot experiments of silver and gold nanoparticles biosynthesis by means of golden algae Mallomonas kalinae. Prepared nanoparticles were characterized by transmission electron microscopy and their size distribution was evaluated using the image analysis. Based on these biosynthesis experiments, further experiments were proposed, particularly the biosynthesis of noble metals nanoparticles with siliceous algae, its optimization and potential applications of these nanoparticles.
