Additionally, the influence of annealing temperature and chitosan coating concentration on the heating efficiency of CZF nanoparticles was investigated, showing that higher annealing temperatures and concentrations led to increased heating efficiency. These studies highlight the potential of CZF nanoparticles for effective AC magnetic heating in magnetic hyperthermia therapy applications.
How are magnetic nanoparticles used for hyperthermia?4 answersMagnetic nanoparticles (NPs) are commonly used for hyperthermia, a form of thermotherapy used to kill tumor cells with heat. These NPs, usually made of magnetic iron oxide such as magnetite or maghemite, can be "switched on" by an external magnetic field, causing them to heat up near tumor cells. Under an applied AC magnetic field, the magnetic spin of the NPs rapidly switches direction, converting magnetic energy into thermal energy. This localized heating, with temperatures of 41-46 °C, inhibits tumor cell growth, kills them, or induces tumor cell apoptosis. Magnetic NPs have been used in tumor thermotherapy since 1996 and have shown synergistic effects when combined with other therapies such as surgery, radiotherapy, and chemotherapy. The size of the NPs is crucial for their heating efficiency, and various parameters such as the surrounding medium, concentration, and field amplitude and frequency can be adjusted to optimize the heating efficiency for different NP sizes. Additionally, magnetic NPs can be coated with proteins such as Bovine Serum Albumin (BSA) to enhance their biocompatibility and specific absorption rate, making them suitable for future hyperthermia applications. The heat transfer from magnetic NPs to the surroundings occurs through a resonance mechanism, allowing for directional control of heat flow and potential activation or release of (bio)molecules anchored to the NPs.
How do magnetic nanoparticles work for hyperthermia treatment?4 answersMagnetic nanoparticles (MNPs) are commonly used in hyperthermia treatment. MNPs, such as magnetic iron oxide nanoparticles (SPIONs), can be "switched on" by an external magnetic field, causing them to heat up near tumor cells. When subjected to an alternating magnetic field, the magnetic spin of the MNPs rapidly switches direction, converting magnetic energy into thermal energy. This localized heating can elevate the temperature of tumor cells, inhibiting growth, inducing apoptosis, or killing the cells altogether. The size of the MNPs is crucial for their heating efficiency, with smaller particles being more effective. Different mechanisms, such as Néel relaxation and Brownian relaxation, contribute to the heating ability of MNPs. MNPs can also be functionalized to selectively target cancer cells and deliver cargo. Hyperthermia treatment can be used alone or in combination with other therapies, such as surgery, radiotherapy, and chemotherapy, to enhance treatment efficacy.
How can Iron oxides magnetic nanoparticles used in MRI?5 answersIron oxide magnetic nanoparticles (IONPs) can be used in MRI for various applications. They can serve as T2 contrast agents, enhancing the T2-weighted MRI contrast. Additionally, IONPs can be used as dual-modality contrast agents (DMCAs) in combination with other imaging modalities such as SPECT or PET, providing both high sensitivity and high spatial resolution. The intrinsic magnetic behavior of IONPs, combined with their ability to be radiolabeled, makes them suitable for SPECT/MRI or PET/MRI applications. Furthermore, IONPs have a high surface-to-volume ratio and can be functionalized with drugs, genes, or bioactive molecules, making them versatile for the diagnosis and treatment of various diseases, including cardiovascular or neurological diseases, tumors, and cancer. Overall, IONPs offer a promising platform for improving the diagnostic capabilities of MRI and advancing medical imaging techniques.
Can magnetic nanoparticles be used to isolate circulating tumor cells?3 answersMagnetic nanoparticles can be used to isolate circulating tumor cells (CTCs). Different strategies have been employed to functionalize the magnetic cores of these nanoparticles, such as biomimetic protein corona precoating and polyethylene glycol (PEG) spacer, supramolecular layer-by-layer (LBL) self-assembly, and aptamer-targeted modifications. These modifications enhance the specificity and sensitivity of the magnetic nanoparticles for capturing CTCs. The captured CTCs can be released with high efficiency and viability for subsequent analysis and culture. The use of magnetic nanoparticles for CTC isolation has shown promising results in both in vitro and in vivo studies, making it a potential tool for early diagnosis, monitoring disease progression, and personalized treatment of tumors.
