Fe is an interesting material for magnetic-based biomedical applicationsdue to its biocompatibility and high magnetization. This work investigates the spin structure of Fe nanodisks as a function of thickness and diameter. Nanodisks were fabricated with thicknesses ranging from 20 to 150 nm and diameters from 200 to 1000 nm. Magnetometry measurements allowed us to determine the geometrical conditions for the formation of a spin-vortex configuration. Furthermore, the magnetic response of Fe nanodisks in water solutions was analyzed under low-frequency magnetic fields. Finally, the effectiveness of these biomaterials has been proven in two-dimensional (2D) cultures of fibroblasts, as well as in substrates with magnetic islands.
Burdina magnetismoan oinarritutako aplikazio biomedikoentzako material interesgarria da, biobateragarritasuna eta magnetizazio handia direla eta. Lan honek Fe nanodiskoen espinaren egitura ikertzen du, lodieraren eta diametroaren arabera. 20nmeta 150 nm arteko lodierako nanodiskoak eta 200nmeta 1000 nm arteko diametroko nanoimanakfabrikatueta karakterizatudira. Magnetometria-neurketek espinekobortize-konfiguraziobat eratzeko baldintza geometrikoak zehaztea ahalbidetudute. Gainera, frekuentziabaxuko eremu magnetikoen peanFe nanodiskoenerantzun magnetikoa aztertu daur-disoluzioetan. Azkenik, biomaterial hauen eraginkortasuna zelula endotelialen eta fibroblastoen hazkuntza bidimentsionaletan (2D) eta irla magnetikoak dituzten substratuetan egiaztatukoda
