Magnasense

Magnasense Technologies, originally founded in Finland in 2006, operates as a subsidiary of the Swedish diagnostics company Magnasense AB (formerly AegirBio). The Finnish entity, Magnasense Technologies Oy, was established in 2010 and was acquired by LifeAssays in November 2015, which later merged with AegirBio. In July 2024, AegirBio rebranded to Magnasense AB to honor the company's origins and the brand recognition of its core technology.

The company centers its operations on a proprietary Magnetic Immunoassay (MIA) platform for point-of-care (POC) diagnostics. This technology utilizes super-paramagnetic particles as labels in lateral flow immunoassays. A key technical advantage is its ability to quantify the entire volume of a sample's capture zone, rather than just the surface, which is typical for optical or fluorescent methods. This approach enhances the sensitivity and precision of diagnostic tests without requiring complex optics, light sources, or color reagents. The business model appears to involve both the development of its own diagnostic kits and the licensing of its platform to partners. Clients span human and veterinary healthcare, food safety, and environmental testing sectors.

Magnasense’s primary product is the Magnia® platform, which includes the portable, battery-powered Magnia® reader. This device is engineered to be a low-cost, robust magnetometer that provides quantitative results for immunochromatographic assays. It is designed for flexibility, allowing test developers to adapt their existing lateral flow cassettes for use on the Magnia® platform, simplifying the transition from other technologies. The company has developed CE-marked tests, such as the Magnia® CRP test, and has a respiratory panel under development. Now as part of Magnasense AB, the technology is being applied to saliva-based diagnostics for therapeutic drug monitoring and infectious diseases.
