The mass transport characteristics of cationic, nonviral liposome-DNA plasmid complexes (lipoplexes) were evaluated over a range of fluid shear stresses. The typical case of stagnant flow transfection was expanded to include controlled fluid convection provided by constant flow through a parallel plate flow chamber. Equations describing the transport of(More)
Superparamagnetic iron oxide nanoparticles produce changes in the surrounding microscopic magnetic field. A method for generating contrast based on the application of an adiabatic preparation pulse and the failure of the adiabatic condition surrounding the nanoparticles is introduced in this article. Images were obtained in the presence and absence of an(More)
