Abstract:	Naravni polimeri so se uveljavili kot obetaven material za sintezo in pripravo nanoporoznih delcev. Eden izmed najbolj raziskanih in uporabljenih naravnih polimerov je alginat, ki ga pridobivajo iz različnih vrst rjavih morskih alg. Zaradi sposobnosti geliranja in nabrekanja ter nekaterih drugih lastnosti je zelo primeren kot nosilec aktivnih učinkovin. V diplomski nalogi smo pripravili 1,5%; 2% in 2,5% alginatne gele: monolite, ki smo jih narezali na koščke in sferične alginatne kroglice, v katere smo vezali nikotinsko kislino kot aktivno substanco. Nato smo jih superkritično posušili s CO2 in tako dobili organske biorazgradljive aerogele.
Keywords:	alginat, aerogeli, nikotinska kislina, škrob, superkritično sušenje, nadzorovano sproščanje.

Title:	SYNTHESIS AND APPLICATION OF BIODEGRADABLE ORGANIC AEROGELS AS DRUG CARRIERS
Abstract:	Natural polymers have established themselves as a promising material for the synthesis and preparation of nanoporous particles. One of the most researched and used natural polymers is alginate, which is obtained from different types of brown seaweed. Due to its ability to gel and swell and some other properties, alginate is very suitable as a carrier for active ingredients. In this thesis, we prepared 1.5%, 2% and 2.5% alginate gels: monoliths, which were cut into small pieces and spherical alginate beads, in which we introduce nicotinic acid as active substance. We then dried by supercritical CO2 and thus obtained biodegradable organic aerogels.
Keywords:	alginate, aerogels, nicotinic acid, starch, supercritical drying, controlled release.
