  • Hydrophobic silica particles and methods of making same
    Patent number: 8530599
    Abstract: A method of preparing hydrophobic silica particles includes the step of reacting together in a single step a mixture of silane ether monomers and organically modified silane ether monomers with a hydrolyzing agent. The method also includes producing hydrophobic silica microparticles and nanoparticles that can include dyes and/or magnetizable components. The silica nanoparticles can be used in the detection, visualization and/or analysis of latent fingerprints.
    Type: Grant

  • Fingerprint analysis using mass spectrometry
    Patent number: 7923682
    Abstract: The present invention is directed to a method for determining the presence of a residue on or within a fingerprint using matrix-assisted mass spectrometric techniques. The matrix-assisted mass spectrometric technique can be selected from Matrix-Assisted Laser Desorption/Ionization Mass Spectrometry Time-Of-Flight Mass Spectrometry (MALDI-TOF-MS) and/or Surface Assisted Laser Desorption/Ionisation Time-Of-Flight Mass Spectrometry (SALDI-TOF-MS).

  • Surface layer affinity-chromatography
    Patent number: 7781225
    Abstract: There is described an affinity-chromatography assay system comprising with an immobilized component containing a bio-reagent and a flowable component containing a complimentary bio-reagent characterized in that the immobilized component is supported on a dip strip or planar surface and the flowable component is adapted to flow down the dip strip of high density. There is also described a method of conducting an affinity-chromatography assay which comprises the use of such an assay system.
