Resumen

Although significantly improved, current treatments against cancer still present remarkable drawbacks related mainly to side effects. The effectiveness of surgery, radiotherapy, chemotherapy and their combinations, besides being limited in some cases, does not always make up for the undesired invasive nature of these treatments. Therefore, the need for new approaches to overcome these difficulties is apparent. Targeted therapies appear at this scene as great potential alternatives for oncology. Among them, nanoparticle based magnetic hyperthermia stands out as a valuable technique. Clinical validation steps have highlighted some major hindrances due to clearance and toxicity, though. In this work, a novel hyperthermia approach is presented, where the targeted cell death was achieved by means of glass-coated magnetic microwires. These microvehicles were embedded into an elastomer-based microfluidic chambers, where the target osteosarcoma cells were cultured. For treatment periods below an hour the proposed method was demonstrated to be highly effective against cancer cells killing 85% of the treated population.
