Blood clot-targeted nanoparticles
First Claim
1. A composition for performing an imaging and/or delivery function with respect to a blood clot in a subject, said composition comprising an emulsion of nanoparticles, wherein said nanoparticles comprise a core consisting of liquid perfluorocarbon which core is coated with lipid/surfactant and which nanoparticles are coupled directly to at least one targeting ligand that is specific for at least one component characterizing blood clots, and wherein the perfluorocarbon is selected from the group consisting of perfluorodecalin, perfluorooctane, perfluorodichlorooctane, perfluoro-n-octyl bromide, perfluoroheptane, perfluorodecane, perfluorotripropylamine, perfluortributylamine, and mixtures thereof, and wherein said nanoparticles further include at least one chelator for a paramagnetic metal ion as a magnetic resonance imaging (MRI) contrast agent, and/or wherein said nanoparticles further include at least one biologically active agent, and/or wherein said nanoparticles further contain at least one radionuclide.

Abstract
Emulsions comprising nanoparticles formed from high boiling perfluorochemical substances, said particles coated with a lipid/surfactant coating are made target-specific by directly coupling said nanoparticles to a targeting ligand. The nanoparticles may further include biologically active agents, radionuclides, and/or other imaging agents.
