  • MULTIMODAL IMAGING METHODS USING MESOPOROUS SILICA NANOPARTICLES
    Publication number: 20150125398
    Abstract: The invention provides particles useful for sequential imaging or for diagnostics or therapeutics. Disclosed is a method to image diagnostic or therapeutic cells in a mammal, comprising: introducing to a mammal a composition comprising mammalian cells comprising mesoporous silica nanoparticles (MSNs) comprising a lanthanide, a fluorophore and an agent detectable by ultrasound; applying ultrasound and/or a magnetic field to the mammal and recording ultrasound and/or magnetic resonance images that include the MSNs; and detecting the presence, location or amount of the MSNs in the mammal.

  • Sequestration of compounds from microorganisms
    Patent number: 8361623
    Abstract: The invention provides novel mesoporous particles and methods for the selective sequestration of organic compounds from microorganisms, such as from various genera and species of algae that produce important organic compounds. The organic compounds can be selectively sequestered, for example, in favor of biodiesel impurities such as sterols and chlorophyll, to provide substantially pure free fatty acids. The free fatty acids can then be esterified to provide pure biodiesel.
