19F spectra of valves – Representative CE spectra of valve leaflets from (A) a rabbit treated with targeted nanoparticles and (B) a rabbit treated with control untargeted nanoparticles. The PFOB peaks correspond to the reference standard included for quantitative comparison. Notice the much stronger signal from the valve of the rabbit treated with targeted particles (CE/PFOB = 4.6) than from the valve of the rabbit treated with nontargeted particles (CE/PFOB = 2.2).
