Abstract

Nanotehnologija je područje koje naglo raste pronalazeći primjenu u znanosti i tehnologiji. Nanočestice srebra zbog svojih antimikrobnih svojstava su trenutačno najzastupljenije u proizvodnji dezodoransa, odjeće, zavoja, otopina za čišćenje, sprejeva i medicinskih proizvoda. U okviru ovoga rada provedena je ekološki prihvatljiva sinteza nanočestica srebra uz upotrebu glukoze kao reducensa. Pri tome su ispitani uvjeti reakcije tj. različite početne koncentracije srebrova nitrata, AgNO3 i glukoze u svrhu nastanka nanočestica što manjih veličina i što veće koncentracije. Provedeno ispitivanje pokazalo je da početna koncentracija glukoze ima blagi utjecaj na reakciju sinteze nanočestica srebra, dok je utjecaj koncentracije AgNO3 veći. Veličina sintetiziranih nanočestica srebra najmanja je pri najnižoj koncentraciji glukoze od 5 mM i najvišoj koncentraciji AgNO3, dok je brzina sinteze nanočestica najveća pri koncentraciji glukoze od 7 mM. Porast koncentracija sintetiziranih nanočestica srebra prisutan je s porastom koncentracije AgNO3.

Abstract (english)

Nanotechnology is a rapidly growing field with its application in science and technology. Due to their antimicrobial properties, silver nanoparticles are currently most prevalent in the production of deodorants, clothing, bandages, cleaning solutions, sprays and medical products. This study demonstrates an environmentally friendly synthesis of silver nanoparticles using glucose as a reducing agent. The reaction conditions ie different initial concentrations of silver nitrate, AgNO3 and glucose, in order to synthesis of nanoparticles of smaller size and high concentration were examined. Performed investigation has shown that initial glucose concentration had a slight influence on the synthesis reaction of silver nanoparticles, while the influence of AgNO3 concentration was greater. The size of synthesized silver nanoparticles is the smallest at the lowest glucose concentration of 5 mM and the highest concentration of AgNO3, while the nanoparticle synthesis rate is higher at the glucose concentration of 7 mM. An increase concentration of synthesized silver nanoparticles is present with an increase of AgNO3 concentration.
