Medical Device R&D Manufacturer
Nuclear medicine has entered the public spotlight due to its significant efficacy in tumor diagnosis and treatment, while the preparation of radiopharmaceuticals must be based on isotopes. Molybdenum-99 is one of the most important isotopes, accounting for 80% of the nuclear medicine market, and is a widely used “star” isotope.
Molybdenum-99 yields Technetium-99m through beta decay. When properly labeled, Technetium-99m can bind to various ligands for functional imaging of multiple organs, such as the brain, heart, liver, and thyroid, enabling the diagnosis of various organ diseases.China has approved 35 domestically produced in vivo radiopharmaceuticals, 16 of which contain molybdenum.
However, the global supply of molybdenum-99 (Mo-99), the parent isotope used as a raw material, is under significant strain. Nearly all medical-grade Mo-99 worldwide relies on production from a handful of foreign nuclear reactors. This dependence has precipitated a production crisis for Mo-99, driven by constraints related to nuclear proliferation and radioactive waste disposal, frequent reactor failures due to prolonged high-load operations, and the impending decommissioning of most of these aging reactors.China faces substantial demand for Molybdenum-99, relies entirely on imports, and is exposed to the risk of supply chain chokepoints.
Current methods for producing Molybdenum-99 include reactor irradiation and electron accelerator-based production. Among these, electron accelerator production is considered one of the major trends in the future development of isotope production due to its high efficiency, convenience, absence of radioactive waste, and superior environmental friendliness. Companies worldwide are actively strategizing in this area, such asU.S. Polaris Company, Canadian CIIC Company, Japanese MPI CompanyandASML (EU)are all actively pursuing strategic layout and commercial development.
Xi’an Medisotope Technology Co., Ltd. (hereinafter referred to as “MSTP”)Through more than a decade of dedicated research and by leveraging its unique advantages, MSTP has established an independent set of production technologies and process flows for producing molybdenum-99 (Mo-99) and other isotopes using electron accelerators. This achievement fills the domestic gap in both the technology and the supply of Mo-99 isotopes, helping to overcome critical bottlenecks in the localization of medical isotopes in China. Notably, MSTP’s electron accelerator-based project for producing Mo-99 and other isotopes was selected by the Ministry of Science and Technology as a disruptive innovation technology.
MSTP, whose corporate name is a transliteration of the English word “medisotope,” was established in 2019.It is a high-tech company specializing in the R&D and technical services of nuclear radiation, nuclear technology, and isotope production, as well as the R&D of related nuclear medicine equipment and software.The company is dedicated to the production and R&D of medical isotopes, such as molybdenum-99, and related products. Its core technology isProduction of medical isotopes such as Molybdenum-99 using accelerators, proprietary ancillary equipment, and key technologies and processes。The company benchmarks against U.S.-based Boston Scientific.

As previously discussed, current methods for producing molybdenum-99 (Mo-99) include reactor-based irradiation and accelerator-based production. Traditional reactor-based production of Mo-99 requires a series of complex operations—such as irradiating high/low-enriched uranium in a nuclear reactor, separating fission products, industrial processing, and solution dispensing—before the product can reach end users. The entire process is technologically complex and involves a lengthy workflow.
MSTP’s electron accelerator-based photonuclear reaction method for bombarding stable molybdenum-100 to produce molybdenum-99 has disrupted the reactor-based uranium-235 fission technology for molybdenum-99 production, offering significant advantages:
In terms of process, products prepared using electron accelerators have fewer impurities and simpler irradiation processing;
In terms of input,Low investment, construction, and operational costs; the production cost of accelerators is 30%-45% that of reactors;
InIn terms of construction period, building the simplest production system for a solution reactor takes more than five years, whereas MSTP’s system requires only two to three years;
InIn terms of layout, enabling regionalized production with low consumption and low transportation costs;
In terms of environmental protection,No risk of nuclear proliferation, reduced radioactive waste;
In terms of approval,Administrative licensing is simple and easy.
Since 2006, after more than ten years of dedicated research and development, the team has established a multi-functional R&D platform. This achievement spans from the initial proposal of methods for producing medical isotopes such as Molybdenum-99, Copper-67, and Actinium-225 using electron accelerators, through theoretical feasibility analysis, simulation calculations, and experimental validation of production principles, to the breakthrough design of key technologies, critical components, and process flows for industrial-scale production., completed small-scale experimental validation.Furthermore, the experimental results are consistent with those obtained by Argonne National Laboratory and NorthStar Medical Radioisotopes in the United States, demonstrating the feasibility of this method for the industrial production of molybdenum-99. On this basis,Pilot-scale cold experiments and Monte Carlo thermal nuclear simulation studies,The design objectives were achieved.
The multi-functional R&D platform established by MSTP is capable not only of large-scale production of Molybdenum-99 (Mo-99), but also of producing imaging isotopes such as Oxygen-15 (O-15), Carbon-11 (C-11), Iodine-123 (I-123), Indium-111 (In-111), and Cobalt-57 (Co-57), as well as targeted therapy isotopes including Copper-67 (Cu-67), Scandium-47 (Sc-47), Rhenium-186 (Re-186), and Actinium-225 (Ac-225).In particular, the production of targeted therapeutic radionuclides with significant market prospects is the ultimate goal of MSTP.“Zhang Quanshi introduced.”
