dc.description.abstractEhun ingeniaritzak kaltetuta dauden ehunen ordezko funtzionalak sintetizatzeko helburua dauka. Horretarako, zelulaz, molekula bioaktiboz eta euskarri porotsuz osatutako matrizeak beharrezkoak dira, hazkuntza eta zelulen diferentziazio prozesuak gerta daitezen. Matrize hauek solidifikatzeko gai den aitzindari baten injekzioz eratu daitezke kaltetuta dauden ehunetan, hau dela eta, hidrogel injektagarriak ikerkuntza arlo biomedikoan izugarri hedatu dira azken urteotan. Biomaterial hauen injektagarriak izateko gaitasuna sare polimerikoen in-situ gurutzamenduan oinarritzen da. Gurutzamendu hauek, alde batetik, interakzio fisiko itzulgarrien bidez eman daitezke, hidrogel termosentikorrak, pH sentikorrak edo ionikoak eratuz. Bestaldetik, erreakzio kimikoetan ere oinarritu daitezke zeinetan hidrogel fotopolimerizagarriak edota entzimek katalizatutako gurutzamendu bidezko hidrogelak lor daitezkeen. Lan honek hidrogel injektagarriak sintetizatzeko erabiltzen diren estrategien eta ehun ingeniaritzan ikertutako sistema desberdinen aplikazioen berrikuspen bat egitea du helburu.; Tissue engineering aims to create functional substitutes for damaged or diseased tissues through complex constructions of living cells, bioactive molecules and three-dimensional porous scaffolds that support the union, proliferation and differentiation of cells. These constructions can be formed by injection of a precursor which can solidify into the defective tissue, which has converted biomaterials such as injectable hydrogels into one of the most promising biomedical research areas of recent years. Injectable hydrogels are based on the in-situ crosslinking of polymer networks. The mechanisms involved in the formation of these gels can be very varied, and are based on both reversible physical interactions, forming thermosensitive hydrogels, sensitive or ionic pH, and chemical reactions, as is the case of photocrosslinked hydrogels or enzymatically crosslinked. This paper aims to review the main strategies currently used for the formation of injectable hydrogels and, in addition, to show brief results on the formation of injectable hydrogels based on chitosan by physical and chemical crosslinking.
