RT Journal Article T1 Beyond Traditional Hyperthermia. In vivo Cancer Treatmentwith Magnetic-Responsive Mesoporous Silica Nanocarriers A1 Guisasola, Eduardo A1 Asin, Laura A1 Beola, Lillianne A1 De la Fuente, J. M. A1 Baeza, Alejandro A1 Vallet Regí, María Dulce Nombre AB In this study we present an innovation in the tumor treatment in vivo mediated by magnetic mesoporous silica nanoparticles (MMSNs). This device was built with iron oxide magnetic nanoparticles embedded in a mesoporous silica matrix and coated with an engineered thermoresponsive polymer. The magnetic nanoparticles act as internal heating sources under an alternating magnetic field (AMF) that increase the temperature of the surroundings, provoking the polymer transition and consequently the release of a drug trapped inside the silica pores. By a synergic effect between the intracellular hyperthermia and chemotherapy triggered by AMF application, significant tumor growth inhibition was achieved in 48 hours after treatment.Furthermore, the small magnetic loading used in the experiments indicates that the treatment is carried out without a global temperature rise of the tissue, which avoids the problem of the necessity to employ large amounts of magnetic cores, as is common in current magnetic hyperthermia.
