To develop carriers for anti-cancer drug delivery, this study reports a biocompatible and thermal responsive controlled drug delivery system based on hollow magnetic nanoparticles (HMNPs). The system is constructed simply by filling the hollow interiors of HMNPs with a phase-change material (PCM), namely, 1-tetradecanol, which has a melting point of 38 °C. The system achieves near “zero release” of both hydrophobic paclitaxel (PTX) and hydrophilic doxorubicin hydrochloride (DOX) and precise “on” or “off” drug delivery in vitro to efficiently induce cell apoptosis. Furthermore, the system displays both infrared thermal imaging and magnetic resonance imaging properties. More importantly, the system demonstrates great potential for thermo-chemo combination cancer therapy in vivo when an alternating magnetic field is applied.

Nanoscale is a high-impact international journal, publishing high-quality research across nanoscience and nanotechnology. Nanoscale publishes a full mix of research articles on experimental and theoretical work, including reviews, communications, and full papers. Highly interdisciplinary, Nanoscale appeals to scientists, researchers and professionals interested in nanoscience and nanotechnology, quantum materials and quantum technology, including the areas of physics, chemistry, biology, medicine, materials, energy/environment, information technology, detection science, healthcare and drug discovery, and electronics. For publication in Nanoscale, papers must report high-quality reproducible new work that will be of significant general interest to the journal's wide international readership. Nanoscale is a collaborative venture between the Royal Society of Chemistry Publishing and a leading nanoscience research centre, the National Center for Nanoscience and Technology (NCNST) in Beijing, China. image block The journal publishes weekly issues, complementing and building on the nano content already published across the Royal Society of Chemistry Publishing journal portfolio. Since its launch in late 2009, Nanoscale has established itself as a platform for high-quality, cross-community research that bridges the various disciplines involved with nanoscience and nanotechnology, publishing important research from leading international research groups.
