Sinteza spinskih označevalcev za ogljikove nanocevke = Synthesis of spin labels for carbon nanotubes : magistrska naloga : magistrski študij laboratorijske biomedicineJerković, OlgaSpinsko označevanje je metoda pritrjevanja stabilnih paramagnetnih molekul na material, ki ga želimo preiskovati, z namenom pridobitve selektivnih strukturnih in dinamičnih informacij z elektronsko ... paramagnetno resonanco, metodo za detekcijo nesparjenih elektronov. Z vključevanjem spinskih sond v izbrani sistem in preučevanjem radikalov z elektronsko paramagnetno resonanco lahko pridobimo informacije o membranskih modelnih sistemih in bioloških membranah. Sintetizirali smo sedem spinskih sond, ki v svoji strukturi vsebujejo ciklični nitroksidni radikal in planarno aromatsko strukturo. Po zaključeni sintezi smo produkte reakcij čistili in ločevali s kolonsko %flash% kromatografijo. Nove spojine smo okarakterizirali s pomočjo masne spektrometrije, infrardeče spektroskopije in elektronske paramagnetne resonance. Pokazali smo, da sinteza nitroksidnih spinskih sond ni težavna in daje dobre izkoristke ter malo stranskih produktov. Rezultati predstavljajo pomembna izhodišča za nadaljnjo optimizacijo sinteze spinskih sond. Le-te se lahko uporabijo pri raziskavah lastnosti (s spinskimi sondami označenih) nanocevk v bioloških sistemih s pomočjo elektronske paramagnetne resonance, spremljanja njihove dinamike in preverjanja morebitnih citotoksičnih in citoprotektivnih učinkov.Type of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [O.
