Maghemite based silicone composite for arterial embolization hyperthermia

Magnetic Nanomaterials for Arterial Embolization and Hyperthermia of Parenchymal Organs Tumors: A Review

“…These methods are based on the use of a liquid carrier medium typically containing magnetic iron oxide nanoparticles due to their good biocompatibility. The carrier medium is usually water or saline in MFH, while, in AEH, it is oily contrast media (Lipiodol Ultra Fluid, France, and its analogs) [56][57][58][59][60][61][62][63], and in-situ gelling materials [64] and low-viscosity polymers [65][66][67][68][69].…”

“…In contrast to MFH, the challenges discussed above can be eliminated in AEH, developed to treat parenchymal organs. The concept of AEH is based on selective capacitive or inductive hyperthermia after transcatheter embolization of a tumor's arterial supply with a mixture of magnetic particles and an embolic agent [65][66][67][68][69]. As a result of embolization, the size of the tumor decreases due to a decrease in the blood supply, leading to partial necrosis of the tumor.…”

Glycerin‐Based Polyurethane Obtained by Inverse Emulsion: Comparison Between Magnetic Induction and Conventional Heating

“…The most common method for promoting reaction heating is through the using of heating plates or blankets. As an alternative to this, the magnetic induction heating system can achieve this by converting electromagnetic into thermal energy, heating the heterogeneous reaction systems from the core to the shell of the micelles …”

“…As an alternative to this, the magnetic induction heating system can achieve this by converting electromagnetic into thermal energy, heating the heterogeneous reaction systems from the core to the shell of the micelles. [4,17,18] The induction heating of materials takes places when tested materials present intrinsic electrical conductive and electromagnetic properties. [19] Since most of the polymers and the reaction media do not show this inherent potential, the incorporation of species with these properties is a critical step of this process, allowing the promotion of the necessary electromagnetic properties to convert the energy of the electromagnetic field in the heat.…”

Microstructure and Magnetic State of Fe3O4-SiO2Colloidal Particles

“…This approach is a prospective replacement of the traditional X-ray computed angiography with radioactive intravenous contrast agents. The use of iron oxide nanoparticles as the agents for the radio frequency arterial embolization hyperthermia is described in the papers [5,6]. Modified commercial embolic materials based on chitosan [7] and gelatin [8] with iron oxide nanoparticles enhancing MRI contrast are tested.…”
