We are delighted to announce that the University of Oxford Innovation Fund IV has invested in Arago Biosciences alongside Oxford Sciences Innovation. Arago has designed the world’s most sensitive light microscope. Arago Biosciences, a spin-out company from the University of Oxford’s Department of Chemistry, has designed a new way of detecting and quantifying molecules. The patent-protected technology allows users to carry out label-free imaging, localisation, and accurate mass determination of single biomolecules in solution. The approach has the potential to revolutionise the characterisation of molecular interactions, making it particularly relevant to the pharmaceutical, biomedical and research sectors.
