The impact of the synthesis on the size of nanoparticles

V magistrski nalogi je predstavljena primerjava dveh metod priprave nanodelcev, znotraj dveh metod smo spreminjali parametre in spremljali vpliv sprememb na velikost nanodelcev. Nanodelci so se pripravljali iz etil celuloze po emulzijske postopku, kjer smo kot polimerne stabilizatorje uporabljali različne polisaharide, ter spreminjali njihove koncentracije. Druga uporabljena metoda je bila dializna metoda, pri kateri smo uporabili različna topila in različne koncentracije etil celuloze. Velikost delcev smo analizirali z DLS metodo in z elektronskim mikroskopom, stabilnost disperzij smo določili z določanjem zeta potenciala.The comparison of two different nanoparticle preparation methods is presented in this master thesis. Within the two methods the parameters were changed and the effect of changes on the nanoparticle size was monitored. Nanoparticles were prepared from ethyl cellulose with emulsion method, as polymeric stabilizers different polysaccharides were used, and in different concentrations. The second used method was dialyzed method, where different concentrations of ethyl cellulose were used. Size of the particles was determined with DLS analysis and with electron microscope, stability of dispersion was determined with zeta potential
