Latest Patents
One of Philippe Dumas's latest patents is focused on the preparation of poly(ethylene oxide)-coated nanoparticles of maghemite. This invention relates to a material consisting of an aqueous dispersion of PEG-coated nanoparticles of maghemite. The process for preparing this material involves polymerizing ethylene oxide in the presence of nanoparticles of maghemite in an aqueous dispersion. The polymerization is initiated using reactive groups capable of initiating the polymerization of ethylene oxide without the addition of a catalyst. These reactive groups are attached to the nanoparticles of maghemite through a coupling agent that includes an alkoxysilyl group. This innovative material has applications as a contrast agent for MRI.
Another significant patent by Dumas involves a protein crystal comprising the processivity clamp factor of DNA polymerase and a ligand. This protein crystal features the β subunit of DNA polymerase III and a peptide that ranges from about 3 to about 30 amino acids, particularly around 16 amino acids. The peptide includes all or part of the binding sequence of a processivity clamp factor interacting protein, which can be prokaryotic or eukaryotic in nature.
