Abstract
Nanotehnologija ima veliki potencijal u mnogim područjima istraživanja te se sve više primjenjuje u raznim granama znanosti i tehnologije. Nanočestice zlata imaju svojstva koja im omogućuju široku primjenu, kao što je primjena u medicini, elektronici i drugim područjima. S obzirom da je potražnja za nanočesticama sve veća, metode sinteze nanočestica moraju biti ekonomičnije i ekološki prihvatljivije. Stoga je, u ovom radu, provedeno ispitivanje uvjeta sinteze nanočestica zlata uz glukozu kao ekonomski i ekološki prihvatljivu metodu njihove sinteze. Ispitan je utjecaj različitih koncentracija glukoze i tetrakloroauratne kiseline u svrhu sinteze što veće koncentracije nanočestica zlata, a što manje veličine uz konstantnu koncentraciju škroba. Reakcije su provedene u fosfatnom puferu na sobnoj temperaturi te uz prisustvo svjetlosti i kisika. Provedeno ispitivanje pokazalo je da početna koncentracija glukoze ima blagi utjecaj na sintezu nanočestica zlata, dok koncentracija HAuCl4 ima značajan utjecaj. Veličina sintetiziranih nanočestica zlata gotovo i ne ovisi o koncentraciji glukoze, dok koncentracija sintetiziranih nanočestica zlata ima blagi rast s porastom koncentracije glukoze.
Abstract (english)
Nanotechnology has an enormous potential in many fields of research and it is increasingly applied in various branches of science and technology. Gold nanoparticles have properties that allow them to be widely used, in medicine, electronics and other fields. As the demand for nanoparticles is increasing, nanoparticle synthesis methods should be economically and environmentally acceptable. Therefore, in this study, the influence of the reaction conditions on glucose-mediated gold nanoparticle synthesis was investigated, as economically and ecologically acceptable method for the synthesis of gold nanoparticles. The influence of varied glucose and tetrachloroauric acid concentrations was examined on the concentration and size of gold nanoparticles. The starch concentration was constant and the synthesis was performed in a phosphate buffer at room temperature with the presence of light and oxygen. This research has shown that the initial glucose concentration had a slight influence on a synthesis of gold nanoparticles, while the influence of HAuCl4 concentration was significant. The size of synthesized gold nanoparticles almost does not depend on glucose concentration and a slight increase in amount of gold nanoparticles with increase of glucose concentration is observed.
