    摘要: A method of identifying a source of a marking fluid applied to a person or an object comprises applying a marking fluid including one or more security markers to a person or an object and illuminating the applied marking fluid to excite the security markers. Photoluminescent emission from the security markers in response to the excitation is measured and compared with one or more pre-defined photoluminescent signatures associated with the source of the marking fluid. The source of the marking fluid is identified based on a match between the detected photoluminescent emission and at least one of the pre-defined photoluminescent signatures.

    摘要: Macromonomers of the formula I are described:Q-B(L-B).sub.n T (I)wherein n is at least 1.0;Q is a polymerizable group;B may be the same or different and is a difunctional block of molecular weight in the range of from 100 to 4000 and wherein at least one B is a perfluorinated polyether of formula II;--OCH.sub.2 CF.sub.2 O(CF.sub.2 CF.sub.2 O).sub.x (CF.sub.2 O).sub.y CF.sub.2 CH.sub.2 O-- (II)wherein the CF.sub.2 CF.sub.2 O and CF.sub.2 O units may be randomly distributed or distributed as blocks throughout the chain and wherein x and y may be the same or different such that the molecular weight of the perfluorinated polyether is in the range of from 242 to 4,000;L is a difunctional linking group; andT is a terminal group.These macromonomers may be used in the production of contact lenses, corneal implants, cell growth substrate or medical implant.
