  • Patent number: 10758630
    Abstract: A topical composition includes a nanoemulsion of a plurality of hydrophobic particles having a hydrophilic coating therein. The hydrophobic particles are derived from the same or different hydrophobic material and each hydrophobic particle has a melting point below the melting point of the respective hydrophobic material. The hydrophobic particles comprise a mean particle size of less than about 10 nm, and the nanoemulsion further includes one or more pharmaceutically active agents.
    Type: Grant
    Filed: September 19, 2012
    Date of Patent: September 1, 2020
    Assignee: The Johns Hopkins University

  • Patent number: 6803208
    Abstract: A method for determining the presence of bacteria in a platelet or red blood cell sample is disclosed. The method includes the steps of: lysing a substantial portion of the platelets or red blood cells; staining the bacteria using a membrane permeable nucleic acid stain; filtering the sample using a membrane filter with a suitable pore size so that a material containing the stained bacteria is retained on the membrane filter; and analyzing the material retained on the membrane filter using epifluorescence microscopy and/or digital image acquisition and analysis to determine the presence of bacteria in the sample. The method allows the detection of bacterial contamination in platelets or red blood cells at clinically significant levels in a relatively short period of time.
