Cancers are fatal diseases that lead to most death of human beings, which urgently require effective treatments methods. Hyperthermia therapy employs magnetic nanoparticles (MNPs) as heating medium under external alternating magnetic field. Among various MNPs, ferrite nanoparticles (FNPs) have gained significant attention for hyperthermia therapy due to their exceptional magnetic properties, high stability, favorable biological compatibility, and low toxicity. The utilization of FNPs holds immense potential for enhancing the effectiveness of hyperthermia therapy. The main hurdle for hyperthermia treatment includes optimizing the heat generation capacity of FNPs and controlling the local temperature of tumor region. This review aims to comprehensively evaluate the magnetic hyperthermia treatment (MHT) of FNPs, which is accomplished by elucidating the underlying mechanism of heat generation and identifying influential factors. Based upon fundamental understanding of hyperthermia of FNPs, valuable insights will be provided for developing efficient nanoplatforms with enhanced accuracy and magnetothermal properties. Additionally, we will also survey current research focuses on modulating FNPs' properties, external conditions for MHT, novel technical methods, and recent clinical findings. Finally, current challenges in MHT with FNPs will be discussed while prospecting future directions.

Cyanine dye-containing nanoparticles have widely been used in "all-in-one" NIR fluorescence imaging (FI)-guided photothermal therapy (PTT) because of their intrinsically large extinction coefficient and available physical and chemical modulation methods to tune absorption and emission wavelengths. The combination of good brightness and excellent tumor-targeting capacity is the key to realize efficient NIR-II FI-guided PTT. In this study, by covalently decorating NIR-II absorptive cyanine dyes with bulky AIE motify, we demonstrate how steric hindrance suppresses π-π stacking-induced fluorescence quenching and contributes to the good brightness of NIR-II FI of subcutaneous glioblastoma.

Clinical diagnostics and biological research are advanced by magnetic theranostic, which uses macromolecule-based magnetic theranostic agents for targeted therapy and diagnostic imaging. Within this review, the interaction of magnetic nanoparticles (MNPs) with biological macromolecules will be covered. The exciting potential of macromolecule-based magnetic theranostic agents to be used as a tool in drug delivery, photothermally therapy (PTT), gene therapy, hyperthermia therapy and photodynamic therapy (PDT) will be discussed.

The basic requirements for the development of radiopharmaceuticals for radionuclide therapy of tumors include marked tumor-specific accumulation and long-term intratumoral retention. We have previously reported an indium-111 (In)-labeled thermoresponsive polymer (polyoxazoline (POZ)) that is soluble at body temperature with rapid clearance from normal tissues but self-aggregates in the tumor upon tumor heating treatment. POZ accumulated in the tumor via self-aggregation under hyperthermic conditions and was retained after stopping heat exposure.

Regrettably, glioblastoma multiforme (GBM) remains the deadliest form of brain cancer, where the early diagnosis plays a pivotal role in the patient's therapy and prognosis. Hence, we report for the first time the design, synthesis, and characterization of new hybrid organic-inorganic stimuli-responsive nanoplexes (NPX) for bioimaging and killing brain cancer cells (GBM, U-87). These nanoplexes were built through coupling two nanoconjugates, produced using a facile, sustainable, green aqueous colloidal process ("bottom-up").
