Special Issue Information

Dear Colleagues,

Hyperthermia is a medical procedure that has been used since the end of the 19th century for the treatment of solid tumors. It consists of heating cancer cells, which are more sensitive to temperature than healthy cells, to around 42 - 45°C. Since the 1980s, the combination of nanoparticles and external physical stimuli has made it possible to limit hyperthermia to the tumor area. This is called localized hyperthermia. Depending on the nature of the nanoparticles and the external physical stimulus, two types of localized hyperthermia treatments can be distinguished: (i) photothermal therapy, PTT, assisted by plasmonic nanoparticles (mainly gold) under near-infrared illumination, NIR, (in the 650-900 nm range); (ii) magnetic fluid hyperthermia (MFH) mediated by superparamagnetic nanoparticles (mainly iron oxides or ferrites) under alternating magnetic fields (AMFs). In both cases, the parameters that influence the photo or magneto-thermal response of the nanoparticles are size, shape or self-assembly. For gold nanoparticles, nanorods, nanostars or nanoshells are the shapes that have the best heating properties. For iron oxide nanoparticles, the three most promising systems are nanocubes, ferrite core–shell nanosystems and self-assemblies.

This Special Issue of Nanomaterials, entitled “Plasmonic and Magnetic Nanoparticles for Localized-Hyperthermia”, aims to highlight magnetic and plasmonic nanomaterials that allow heating properties to be increased in solution, in cellulo and in vivo. The study and understanding of synergistic effects in systems that combine magnetic and plasmonic nanoparticles will also be considered.

Combination therapy for cancer is expected for the synergetic effect of different treatments, and the development of promising carrier materials is demanded for new therapeutics. In this study, nanocomposites including functional nanoparticles (NPs) such as samarium oxide NP for radiotherapy and gadolinium oxide NP as a magnetic resonance imaging agent were synthesized and chemically combined with iron oxide NP-embedded or carbon dot-coating iron oxide NP-embedded carbon nanohorn carriers, where iron oxide NP is a hyperthermia reagent and carbon dot exerts effects on photodynamic/photothermal treatments. These nanocomposites exerted potential for delivery of anticancer drugs (doxorubicin, gemcitabine, and camptothecin) even after being coated with poly(ethylene glycol). The co-delivery of these anticancer drugs played better drug-release efficacy than the independent drug delivery, and the thermal and photothermal procedures enlarged the drug release. Thus, the prepared nanocomposites can be expected as materials to develop advanced medication for combination treatment. Full article

This paper presents various control system design techniques for temperature control of Magnetic Fluid hyperthermia. The purpose of this research is to design a cost-effective, efficient, and practically implementable temperature controller for Magnetic Fluid hyperthermia, which is presently under research as a substitute to the radiation and chemotherapy treatment of cancer. The principle of this phenomenon centers on the greater sensitivity of tumor cells to changes in temperature in comparison to healthy cells. Once the nanoparticles reach the desired tissue, it can then be placed in a varying magnetic field to dissipate the heat locally by raising the temperature to 45 °C in order to kill cancerous cells. One of the challenging tasks is to maintain the temperature strictly at desired point i.e., 45 °C. Temperature controller for magnetic fluid hyperthermia provides the tight control of temperature in order to avoid folding of proteins and save the tissues around the cancerous tissue from getting destroyed. In contrast with most of the existing research on this topic, which are based on linear control strategies or their improved versions, the novelty of this research lies in applying nonlinear control technique like Sliding Mode Control (SMC) to accurately control the temperature at desired value. A comparison of the control techniques is presented in this paper, based on reliability, robustness, precision and the ability of the controller to handle the non-linearities that are faced during the treatment of cancer. SMC showed promising results in terms of settling time and rise time. Steady state error was also reduced to zero using this technique. Full article
