Magnasense Technologies Magnasense Technologies has developed a Point of Care assay system based on antibodies labelled with paramagnetic particles. Magnetism can be measured with great sensitivity and precision. This, plus the absence of magnetic background in biological materials enables rapid, accurate and precise assays to be readily developed. The system is compact and easily integrated into laboratory, near patient and industrial settings. Assays for C-Reactive Protein, infectious diseases and toxins are being actively developed. Magnasense Technologies is actively seeking partners for test and technology development.
