Field Flow Fractionation
The capillary electrophoresis assay described in this study is reproducible, more sensitive and faster than other analytical tests. The samples used in the capillary electrophoresis assay were obtained from brain and the lymphoid system of the animals. The sensitivity of this assay made it possible to test samples from other tissues that contain much less abnormal prion protein than brain sampl...
متن کاملDual-field and flow-programmed lift hyperlayer field-flow fractionation.
Field and flow programming and their combination, dual programming, are shown to extend the particle size range to which a single flow/hyperlayer field-flow fractionation (FFF) run is applicable to approximately 1-50 microns. The rationale for programming flow/hyperlayer FFF (or other forms of lift hyperlayer FFF) is to expand the diameter range of micron size particles that can be resolved in ...
متن کاملA microfabricated thermal field-flow fractionation system.
A microscale thermal field-flow fractionation (micro-TFFF) system has been designed, fabricated, and characterized. Motivation for miniaturization of TFFF systems was established by examining the geometrical scaling of the fundamental TFFF theory. Miniaturization of conventional macroscale TFFF systems was made possible through utilization of micromachining technologies. Fabrication of the micr...
متن کاملCellular Separation via Dielectrophoretic Field-Flow-Fractionation
I present a brief review of a cellular separation technique known as dielectrophoretic field-flowfractionation. The technique relies upon suspending different cells at different heights within a laminar flow profile. The differentially suspended cells, thus, travel at different speeds and elute from the flow chamber at different times resulting in successful separation. An alternate fabrication...
متن کاملContinuous force field analysis for generalized gradient vector flow field
We propose a modification of the generalized gradient vector flow field techniques based on a continuous force field analysis. At every iteration the generalized gradient vector flow method obtains a new, improved vector field. However, the numerical procedure always employs the original image to calculate the gradients used in the source term. The basic idea developed in this paper is to use t...
