  • Safe biodegradable fluorescent particles
    Patent number: 7781224
    Abstract: A human-safe fluorescence particle that can be used for fluorescence detection instruments or act as a safe simulant for mimicking the fluorescence properties of microorganisms. The particle comprises a non-biological carrier and natural fluorophores encapsulated in the non-biological carrier. By doping biodegradable-polymer drug delivery microspheres with natural or synthetic fluorophores, the desired fluorescence can be attained or biological organisms can be simulated without the associated risks and logistical difficulties of live microorganisms.
    Type: Grant
    Filed: August 9, 2006
    Date of Patent: August 24, 2010
    Assignee: Lawrence Livermore National Security, LLC
    Inventors: Sue I. Martin, David P. Fergenson, Abneesh Srivastava, Michael J. Bogan, Vincent J. Riot, Matthias Frank
