SP Labo

SP Labo is a Japanese biotechnology company specializing in the development and application of superparamagnetic iron oxide nanoparticles (SPIONs) for medical diagnostics and therapeutics. Founded in 2011, the company leverages its proprietary nanoparticle platform to produce high-performance imaging agents and innovative cancer treatments. Their core product, ferucarbotran, is utilized as a contrast agent for magnetic resonance imaging (MRI) and as a tracer for magnetic particle imaging (MPI). Beyond diagnostics, SP Labo is advancing a therapeutic pipeline focused on magnetic hyperthermia, which uses alternating magnetic fields to generate localized heat in nanoparticle-loaded tumors to induce cell death. The company aims to provide minimally invasive theranostic solutions for solid tumors, including liver and breast malignancies.
