| contents | <p><span>MXenes are two-dimensional transition metal carbides that have emerged as versatile </span><span>nanomaterials. Their distinctive physicochemical properties and surface characteristics </span><span>make them ideal platforms for engineering hybrid nanomaterials. The combination of </span><span>MXenes and magnetic nanoparticles (MNPs) into a single nano-object leads to materials </span><span>with interesting properties (ferrimagnetism, mechanical strength, and conductivity, etc.) </span><span>for a broad range of applications. MXenes exhibit good compatibility and excellent </span><span>photothermal (PTT) properties; while MNPs, particularly iron oxide nanoparticles </span><span>(IONPs), are exploited for biomedical applications through magnetic hyperthermia </span><span>(MHT). This work focuses on the development of hybrid nanomaterials combining </span><span>MXenes and IONPs, prepared through a simple, holistic, and reproducible method. The </span><span>surface of delaminated MXenes (dMXenes) sheets was covered with well-defined shape </span><span>IONPs of 14 nm. We have used faceted nanoparticles, to achieve point-of-reference </span><span>magnetic hyperthermia performance. The surface loading of IONPs on the MXenes was </span><span>controlled by varying the MXene-to-MNPs mass ratio from 10:90 to 90:10The potential </span><span>of the hybrids for photo-magnetic hyperthermia was evaluated using near-infrared (NIR) </span><span>light (1064 nm, 1 W) and alternating magnetic fields (AMFs) of 9.5–17.0 kA/m and 282 </span><span>kHz, determining their specific absorption rates (SAR) values. While for MHT, SAR </span><span>values are up to 150 W/g (Fe</span><span>3</span><span>O</span><span>4</span><span>) for 50:50 hybrid, the characterization of this new </span><span>nanomaterial revealed a synergistic behavior in PTT, achieving SAR values up to 577 </span><span>and 1106 W/g (hybrid), for 50:50 and 70:30 mass ratio hybrids, respectively. This work </span><span>demonstrates the heat dissipation capability of MXene/IONPs hybrids under AMFs and </span><span>via laser excitation.</span> </p> |
