Sara Freitas, an IFIMUP master student under the supervision of Dra. Célia Sousa and Dr. João Horta, won the Best Poster Award contest in the 2021 Intermag Virtual Conference on the “Bio-applications of Magnetism” section. The poster was about “Multifunctional Fe-Au nanostructures for biomedical applications” and the presented work had the collaboration of several people namely João H. Belo, Célia T. Sousa, Ricardo Magalhães, H. Crespo, M. Canhota, Miguel Peixoto de Almeida, Eulália Pereira, B. Almeida, B.M. Silva and João P. Araújo.
The main goal of the work is to produce multifunctional Iron-Gold nanostructures with high heating performance when stimulated with radiation and with alternating magnetic fields, for applications in controlled and localized hyperthermia. The nanostructures were produced by two methods, through the ablation of Iron and Gold targets with a femtosecond pulsed laser in liquids (such as ethanol) and by electrodeposition in self-organized alumina matrices.
