Size Separation of Exosomes and Microvesicles Using Flow Field-Flow Fractionation/Multiangle Light Scattering and Lipidomic Comparison.

Analytical Chemistry, 2022
Extracellular vesicles (EVs) are cell-derived membrane-bound particles, including exosomes and microvesicles that differ in cellular origin, content, and lipid composition.

Field-Flow fractionation for nanoparticle characterization.

Journal of Separation Science, 2021
This review presents Field-Flow Fractionation: The elements of theory enable the link between the retention and the characteristics of the nanometer-sized analytes to be highlighted.

Nanoplastic Analysis by On-line Coupling of Raman Microscopy and Field-Flow Fractionation Enabled by Optical Tweezers.

Analytical Chemistry, 2020
Nanoplastic pollution is of emerging environmental concern, but current analytical approaches are facing limitations in this size range. However, the coupling of nanoparticle separation with chemical characterization bears potential to close this gap ...

Field-Flow Fractionation

Journal of Fluid Mechanics, 1983
If different contaminant species are subject to different transverse drift rates (e.g. gravitational settling), then there is a tendency for the species to separate out. The efficiency of this separation depends upon the relative shapes of the longitudinal concentration distributions.

Field‐programmed flow field‐flow fractionation

Journal of Microcolumn Separations, 1995
AbstractA flow field‐flow fractionation (FIFFF) system capable of accurate and reproducible flowrate programming has been assembled and tested. This modified system consists of three computer‐controllable pumps, two that regulate the incoming and outgoing cross flowrates and one that controls the channel flowrate.
