  • Patent number: 8841633
    Abstract: A method and apparatus for measuring a vitamin K antagonizing anticoagulant present in a sample (116), arranged to: irradiate (304) the sample (116) with light from a light source (114) for exciting the anticoagulant through its absorption of the light, the excitation of the sample (116) resulting in a fluorescent emission from the sample (116); measure (306) the fluorescent emission from the sample (116); determine (308) a fluorescence lifetime (T1) of the fluorescent emission of the sample (116); determine (310) an intensity (A1) of the fluorescent emission at the fluorescence lifetime (T1); and determine (312) a amount (c) of the anticoagulant, as a function of the intensity (A1) of the fluorescent emission at the fluorescence lifetime (T1).

  • Publication number: 20050027102
    Abstract: Molecularly imprinted polymers can be utilized in stereo- and regio-selective synthesis. These systems can be utilized, e.g. for peptide synthesis, by selectively coordinating reactants at a predetermined preformed cavity. Further, such polymers may be used for the selective removal of one enantiomeric species from solution, allowing reaction to be directed to another species in bulk solution leading to stereoselective and/or regio-selective synthesis in the cavity of for instance peptides. Additionally, when utilized as regioselectively interacting protectioning matrices, these polymers can direct reaction to an alternate centre of a reacting substrate.
