<p>Metalne nanočestice spadaju u nanomaterijale sa širokim spektrom<br />primena u plazmonici, elektronici, katalizi i biomedicini.<br />Razvijene su brojne metode njihove fabrikacije. U ovoj disertaciji<br />predstavljena je mogućnost sinteze metalnih nanočestica korišćenjem<br />jednog novog metoda, u kojem se koristi granični sloj elektrolita i<br />plazme. Niskotemperaturni joni iz plazme se pomoću električnog polja<br />uvode u elektrolit sa prekursorskim materijalom. Ovako uvedeni joni<br />iniciraju oksido-redukcione reakcije sa prekursorom metala u<br />nanometarski tankom sloju na površini elektrolita.<br />Razvijen je generator niskotemperaturne plazme baziran na<br />konfiguraciji dielektričnih barijernih pražnjenja. Urađena je njegova<br />karakterizacija i merenje struje formiranih reaktivnih jona. Metod je<br />verifikovan na primeru nanočestica srebra i platine.</p> / <p>Metallic nanoparticles are nanomaterials with wide range of applications in<br />plasmonics, electronics, catalysis and biomedicine. Thus, a number of<br />methods for their fabrication exist. In this dissertation a possibility of<br />synthesis of metallic nanoparticles using а new method, which exploits an<br />interface between plasma and electrolyte. By means of an electric field, lowtemperature<br />ions from plasma are introduced into the electrolyte with<br />precursor material. The ions from plasma start redox reactions with metal<br />precursor ions within a nanometer-thin layer on the surface of the electrolyte.<br />Nonthermal plasma generator based on dielectric barrier discharges was<br />developed and characterized. Currents of generated reactive ions were<br />subsequently measured. The developed method was verified by synthesis of<br />silver and platinum nanoparticles.</p>
