The key goals of the MAGNET-CELLPATCH project are: a) the training of a talented experienced researcher, Dr. Castellanos-Rubio, in the fast growing fields of nanotechnology, microfabrication, biomedicine and healthcare industry, in which the host and partner institutions have an extensive knowledge and expertise; and, b) the development, optimisation and evaluation of cost-efficient multimodal magnetic cellular-patches for high performance theranostics. The interdisciplinary training program includes the use of advanced characterisation techniques, as XAS and SAXS, and the evaluation of the material in therapy (hyperthermia-chemotherapy) and diagnosis (MRI) of colorectal cancer. The fellow is a skilled researcher that during her undergraduate and postgraduate career has gained strong experience in the fabrication and characterization of biocompatible magnetic nanoparticles and inorganic-polymeric microstructures with magnetothermal properties. To further boost her career, she needs to gain expertise in sophisticated data-capture instrumentation (such as synchrotron radiation sources), in in-vitro and in-vivo experimental studies and in MRI technique, in which the UPV/EHU has a world-recognised expertise. Moreover, through secondments at academic and industrial co-hosts, at the UCL and NIT respectively, she will gain additional training in preclinical experiments in the field of magnetic-drug-targeting and in production protocols of medical devices, scaling-up options, cost-reduction strategies, quality-controls and market-ready items designs. This multidisciplinary project explicitly addresses a world-wide societal challenge in health, namely, the development of new materials for cancer treatment. In addition, it will also increase the fellow´s supervision and teaching experience, project and intellectual property management expertise, research funding and proposal writing, which will assist her in acquiring necessary competences to reach professional maturity.
