20.500.12556/RUL-132321 Proactive release of antimicrobial essential oil from a "smart" cotton fabric Two temperature and pH responsive submicron hydrogels based on poly(N-methylenebisacrylamide), chitosan and β-cyclodextrines (PNCS/CD hydrogel) with varying poly(N-isopropylacrylamide) to chitosan ratios were synthesized according to a simplified procedure, reflecting improved stimuli responsive properties and excellent bio-barrier properties, granted by incorporated chitosan. Hydrogels were applied to cotton-cellulose fabric as active coatings. Subsequently, antimicrobially active savory essential oil (EO) was embedded into the hydrogels in order to develop temperature- and pH-responsive cotton-cellulose fabric with double antimicrobial activity, i.e., bio-barrier formation of chitosan along with the proactive release of savory EO at predetermined conditions. The influence of the hydrogels chemical composition on stimuli responsive and antibacterial properties were assessed. Both PNCS/CD hydrogels showed stimuli responsiveness along with controlled release of savory EO. The chemical composition of the hydrogels strongly influenced the size of the hydrogel particles, their temperature and pH responsiveness, and the bio-barrier forming activity. The increased concentration of chitosan resulted in superior overall stimuli responsiveness and excellent synergy between the antimicrobial activities of the hydrogel and released savory EO. antimicrobial activity chitosan essential oils smart textiles stimuli-responsive hydrogel ß-cyclodextrin protimikrobna aktivnost hitozan eterična olja pametne tekstilije hidrogeli odzivni na dražljaje ß-ciklodekstrin true false true Angleški jezik Slovenski jezik Članek v reviji 2021-10-21 12:19:51 2021-10-21 12:19:52 2022-09-12 04:11:53 0000-00-00 00:00:00 2019 0 0 18 str. iss. 4, art. 242 Vol. 9 10 April 2019 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 677 2079-6412 10.3390/coatings9040242 3594608 RAZ_Stular_Danaja_2019.pdf RAZ_Stular_Danaja_2019.pdf 1 9E6BBF9E780217A515C68FC6AD5EBDF9 0a22142fac9b640894832a74131e1d0b29025bb132cf688f28e4fc094b1543f3 a4b4d12d-3258-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=149917 https://www.mdpi.com/2079-6412/9/4/242 1 6ae63237-3258-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=149916 Naravoslovnotehniška fakulteta Fakulteta za farmacijo 0 0 0
