“…4,[17][18][19][20] These branches are typically formed in twinned particles from symmetry breaking events, [19][20][21] or via polymorphism where arms of an hcp polymorph are grown from seeds of an fcc polymorph. 21,22 For IONPs, there are several synthetic strategies to form anisotropic morphologies, in particular nanoflowers have been formed via water based co-precipitation pathways, 23 and the thermal decomposition synthesis in polyol solvents. 24,25 For thermal decomposition synthesis of branched NPs in other (i.e., non-polar) organic solvents, there is one study on tetrapods.…”

“…8,46 Thus, the heterogeneity is very important to smaller nanostructures, in which surface atoms are more significant. Probably, because of that, some experimental results have shown that small nanoparticles seem to be more efficient heat sources than the LRT model predicts, 24,43,47 revealing that this model (based on meso and macroscopic properties) could be neglecting important properties of heterogeneity. So, the core-shell theoretical models are evidently needed, but until now, only Monte Carlo simulation approaches have been developed.…”

The phenomenon of heat dissipation by magnetic materials interacting with an alternating magnetic field, known as magnetic hyperthermia, is an emergent and promising therapy for many diseases, mainly cancer. Here, a magnetic hyperthermia model for core-shell nanoparticles is developed. The theoretical calculation, different from previous models, highlights the importance of heterogeneity by identifying the role of surface and core spins on nanoparticle heat generation. We found that the most efficient nanoparticles should be obtained by selecting materials to reduce the surface to core damping factor ratio, increasing the interface exchange parameter and tuning the surface to core anisotropy ratio for each material combination. From our results we propose a novel heat-based hyperthermia strategy with the focus on improving the heating efficiency of small sized nanoparticles instead of larger ones. This approach might have important implications for cancer treatment and could help improving clinical efficacy.

An alternating magnetic field (AMF)-stimuli responsive nanodevice based on magnetic nanoparticles (MNP) functionalized with water-soluble carboxylate-substituted pillar[5]arene (CP[5]A), namely MNP-CP[5]A, as a multiplatform for cancer treatment has been designed. MNP-CP[5]A was loaded with doxorubicin (DOX), showing a loading capacity of 9.5 mg g-1. The nanodevice demonstrated good colloidal stability, superparamagnetic behavior, and was capable to generate detectable heat in solution induced by AMF application. DOX release, monitored by ultraviolet-visible (UV-Vis) spectroscopy, was investigated by varying the temperature (37 and 45 °C) without AMF and in the presence of AMF (frequency (f) = 307 kHz, field amplitude (H) = 200 Oe, 45 °C) at pH = 7.4. Thermo-induced DOX release without AMF was 1.9% (1.8 μg mL-1) and 2.3% (3.3 μg mL-1) at 37, and 45 °C within 50 min, respectively. In an AMF DOX release increased to 5.7% (8.2 μg mL-1) within 50 min. Therefore, MNP-CP[5]A-DOX works as a chemo-hyperthermia nanodevice.
