Size distribution of liposomes by flow field-flow fractionation.
The applicability of field-low fractionation (FFF) to the characterization of liposomes is discussed and theoretically described. Because of fundamental differences in their driving forces, sedimentation FFF and flow FFF measure different vesicle properties. Sedimentation FFF, although used previously to measure vesicle sizes and size distributions, is fundamentally a technique that measures th...
متن کاملFast Optimal Control of Asymmetric Flow Field Flow Fractionation Processes
We present optimization problem for Asymmetric Flow Field Flow Fractionation, which is a widely used technique for segregation of two or more particles of submicron scale, according to their hydrodynamic radius. We give a short description of AF4 and present one way coupled model. For an optimization problem we use the sensitivities due to the special structure of the objective functional for t...
متن کاملField 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 کاملDielectrophoretic field-flow fractionation of electroporated cells.
We describe the development and testing of a setup that allows for DEP field-flow fractionation (DEP-FFF) of irreversibly electroporated, reversibly electroporated, and nonelectroporated cells based on their different polarizabilities. We first optimized the channel and electrode dimensions, flow rate, and electric field parameters for efficient DEP-FFF separation of moderately heat-treated CHO...
متن کاملThermal Field-Flow Fractionation of Acrylic Copolymers
A new thermal field-flow fractionation (ThFFF) method has been developed for the separation and analysis of polyacrylates and acrylic-styrene copolymers. This important class of polymers is commonly used as pressure sensitive adhesives, in coatings and paintings, and as the basis for polyelectrolyte materials. The structure and chemical composition of these polymers play a vital role in the end...
