Magnetic nanoparticle hyperthermia: companies, startups and research

New Phase Ltd. and Magnetic Insight Inc. are identified as commercial participants relevant to magnetic nanoparticle hyperthermia. New Phase partnered with Mayo Clinic to install a hyperthermia system for cancer research, while Magnetic Insight develops magnetic particle imaging technology relevant to assessing magnetic colloids and integrating imaging with hyperthermia. The available information does not establish a broad list of particle manufacturers.

Five startups are listed in the field, and Magnetic Insight Inc. is the specifically profiled startup. Its work centers on magnetic particle imaging, which is relevant to assessing magnetic colloids and combining imaging with hyperthermia. The available facts do not provide comparative commercial or clinical results to rank startups by promise.

Charotar University of Science & Technology, Vellore Institute of Technology and the University of Washington are among the research organizations active in this area. Their work includes iron oxide or ferrite particles, coatings, heating behavior and cancer applications. Recent research also includes Texas Tech University on particle design for imaging and hyperthermia, and Nagoya University on intracellular hyperthermia and cancer immunotherapy.

Funding data records $15,352,090 across 31 grants since 2020. The associated funding-round records show 14 rounds totaling $1,284,795,748. These are the recorded totals; the listed rounds include broad institutional financings, so they should not be read as a measure of capital devoted exclusively to magnetic nanoparticle hyperthermia.

Jiangsu Shagang Group leads the listed patent holders with 3 patents. Aerox Advanced Polymers S.L., Southeast University, ZHANGJIAGANG RONGSHENG SPECIAL STEEL Co., Jiangsu Shagang Iron & Steel Co., Ltd, and Shaanxi Baici Kangda Medical Technology Co Ltd each have 2 listed patents. The holder data shows a concentrated set of small portfolios rather than a single dominant patent owner.

Patent activity declined 50% in the last 12 months compared with the previous 12 months, while 21 patents fall within the last 24 months. Publication activity is moving in the opposite direction: 692 publications appeared last year, with growth of 27.2%. This contrast suggests research is expanding faster than recent patenting.

In August 2026, Texas Tech researchers examined how iron oxide core size and PEG coating affect magnetic particle imaging and hyperthermia performance. A separate study investigated how cobalt-ferrite particle shape relates to magnetic and magnetothermal properties. In July 2026, Huazhong University of Science and Technology reported a nanothermometry method incorporating magnetic dipole interactions, addressing the challenge of estimating temperature during treatment.

The main approaches are iron oxide nanoparticles, ferrite nanoparticles, particle architecture, heating mechanisms and field delivery. Iron oxide and ferrite approaches focus on material composition; architecture tunes size, shape and coatings; heating-mechanism studies examine how particles generate heat; and field-delivery work addresses where heating occurs. Each must balance effective, localized heating with measurement, particle distribution and biomedical suitability.

Cancer treatment is the largest listed application, with 346 documents. Other applications include combination therapy, drug delivery and bone tumors. Recent research also explores intracellular hyperthermia and cancer immunotherapy, while studies examine pairing hyperthermia with radiation or therapeutic agents. These application areas reflect both direct heating and its use alongside other treatments.
