Summary: We investigated the evolution of micro- and nano-porosity in the spines and test plates of Paracentrotus lividus sea urchins during the heat-mediated crystallization of remnant ACC and the destruction of intracrystalline organic molecules. Our findings demonstrate the presence of nanopores likely filled with hydrated organics and visualize the evolution of nano- to micro-pores induced by heating. The growth of nanopores is controlled by Ostwald ripening, and the diffusion mechanisms differ between the test plates and spines.

Summary: Magnetic nanoparticles (MNPs) have shown great potential in thermo-therapeutic modalities such as magnetic fluid hyperthermia (MFH) and photo-thermal therapy (PTT). In this study, MnFe2O4 nano-flowers were synthesized and utilized as nano-heat generators for MFH and PTT. The material exhibited effective heating under alternating magnetic field (AMF) and impressive heating ability under near infra-red (NIR) irradiation. The results indicated that MnFe2O4 nano-flowers had higher intrinsic loss power compared to commercially available ferro-fluids and showed significant cell death during photo-thermal treatment.
