  • Method for determining the propensity for calcification
    Patent number: 9651566
    Abstract: The present invention relates to a method for determining the propensity of a fluid for calcification characterized by the following steps: (i) adding a soluble calcium salt and a soluble phosphate salt to a sample of the fluid; (ii) incubating the sample at conditions allowing the formation of calciprotein particles (CPPs); and (iii) determining one or more of the following: (a) the rate of the formation of primary and/or secondary CPPs; (b) the amount of primary and/or secondary CPPs; and/or (c) the rate of the transition of primary CPPs into secondary CPPs, wherein an increase in one or more of (a), (b) and/or (c) of step (iii) indicates an increased propensity of the fluid for calcification.

  • CONTROL OF THE TOXICITY OF GOLD NANOPARTICLES
    Publication number: 20110300532
    Abstract: The present invention relates to gold nanocluster compounds, especially gold nanoparticles, having a reduced toxicity, especially cytotoxicity, which are preferably appropriate for use in medical diagnostics such as medical imaging (e.g. X-ray, CT etc.), said gold nanocluster compounds comprising a core of at least one gold atom and at least one ligand bound to said core, wherein the reduction of toxicity, especially cytotoxicity, of said gold nanocluster compound is controlled and/or adjusted via its ligand structure and/or its ligand chemistry.
