Laburpena: Parametro biologikoak neurtzeko sentsore-plataforma adimendunak sortzea gainazalak eraldatzearen arrazoi nagusienetako bat da. Kontzentrazio baxuko disoluzioak neurtzeko, hautakortasun handia behar denerako edo sentikortasun itzela nahi den egoeretan neurketak egin ahal izateko, sentsore hauen garapena beharrezkoa da. Horrez gain, osasungintzan erabili ahal izateko, biobateragarritasuna ezinbesteko ezaugarria denez, polimerozko sentsoreen erabilpena hazi egingo dela aurresan daiteke. Esparru honetan, oso erabilia den poli(metilmetakrilatoa)ren historia, gaur egun gainazalaren modifikazioak egiteko teknika erabilienak eta horiek eragindako modifikazioa karakterizatzeko moduak azaltzen dira lan honetan. Gainera, poli(metilmetakrilatoa)n eginiko zenbait modifikazio eta emaitza erakusten dira eraldaketen parametroak optimizatu nahian. Hitz gakoak: Gainazalaren eraldaketa, poli(metilmetakrilatoa).Abstract: The need of measuring biological indicators is arousing new challenges for the polymer surface modification. Sensors capable of detecting substances in low concentration, when high selectivity is the key feature or when high sensitivity is needed, are the perfect solution. For using them in medical applications, the biocompatibility is a must-have feature and is then when smart polymer sensing platforms have their success. In this framework, the history of one of the most used polymer poly(methylmethacrylate), most common surface modification techniques and charac-EKAIA 31.indd 67 EKAIA 31.indd 67
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
