Abstract:Srebro je znano kot močan naravni antibiotik. Kot aktivna protimikrobna komponenta se je dobro uveljavilo tudi na področju izdelave medicinskih oblog za oskrbo ran. Namen diplomskega dela je bila vezava srebra na celulozni nosilec (viskozna koprena) in spremljanje njegovega sproščanja v fiziološko okolje. Z uporabo fiziološkega medija in primerne membrane smo skušali simulirati rano in se tako približati realnemu dogajanju na rani. Za sproščanje srebra z viskozne koprene smo kot in vitro sistem uporabili modificirano Franz-ovo difuzijsko celico. Sproščanje smo spremljali z merjenjem koncentracije srebra s pomočjo metode atomske absorpcijske spektroskopije. Uspešno nam je uspelo vezati srebro različnih koncentracij na viskozno kopreno. Iz rezultatov sproščanja pa sklepamo, da je prišlo do zamašitev por membrane v Franz-evi difuzijski celici, saj se je iz vzorcev z različnimi vezanimi koncentracijami srebra sprostil enak delež srebra.

Title:DETERMINATION OF SILVER IN THE CELLULOSE MATERIAL AND ITS TRANSFER INTO PHYSIOLOGICAL ENVIRONMENT
Abstract:Silver is known as a powerful natural antibiotic. As an active antibacterial component it is well established in the field of medical dressing manufacture for wound care. The purpose of this diploma work was to bind silver on a cellulose matrix (viscose non-woven) and monitor its release in the physiological environment. Using a physiological medium and an appropriate membrane we simulated the wound and the processes inside it. We used a modified Franz diffusion cell as an in vitro system for silver release from the viscose non-woven. The method of atomic absorption spectroscopy was used to determine the concentration of released silver. Since the same amount of silver was released from samples with different initial concentrations, we can conclude that blocking of the membrane in Franz diffusion cell occurred during the release study.
Keywords:silver nano-particles, silver binding, silver release, antimicrobial properties, atomic absorption spectroscopy
