Miniaturized asymmetrical flow field‐flow fractionation: Application to biological vesicles
Journal of Separation Science, 2007AbstractAsymmetrical flow field‐flow fractionation (AFlFFF) has been carried out in a miniaturized channel by reducing the channel dimensions. Performance of the miniaturized AFlFFF (mAFlFFF) channel was evaluated with standard proteins and polystyrene latex spheres from nanometer to micrometer size.

Circular Asymmetrical Flow Field-Flow Fractionation for the Semipreparative Separation of Particles
Analytical Chemistry, 2003A new technique for the separation and characterization of particles and polymers based on asymmetrical flow field-flow fractionation was developed. The new circular asymmetrical flow field-flow fractionation instrument (CAFFFE) resembles a quasi-parallel arrangement of 12 individual flow channels.

Aptamer–protein binding detected by asymmetric flow field flow fractionation
Journal of Chromatography A, 2013Asymmetric flow field flow fractionation (AF4) should be suitable for the study of aptamer-target binding, because its gentle separation would impose little disturbance to the complex structure, and it can use carrier solutions with high salt concentrations to provide the most optimal interaction environment to the complex.

Present situation and development trends of asymmetrical flow field-flow fractionation
Chinese Journal of Chromatography, 2017Field-flow fractionation (FFF) is a kind of mature separation technologies in the field of bioanalysis, feasible of separating analytes with the differences of certain physical and chemical properties by the combination effects of two orthogonal force fields (flow field and external force field).

Optimization of asymmetrical flow field-flow fractionation
LC GC North America, 2011Asymmetrical flow field-flow fractionation can be used on a routine basis to separate high molecular weight compounds as an alternative to size-exclusion chromatography (SEC), but the principle of separation is very different and a different approach is required for optimization.

The fractionation of natural nanoparticles by Asymmetrical Flow Field Flow Fractionation (As-Fl-FFF) was optimised by considering the following operating conditions: ionic strength, surfactant concentration and crossflow rate. The method performances such as fractionation recovery and fractionation efficiency were evaluated on a stable solution of ...

Size Characterization and Quantification of Exosomes by Asymmetrical-Flow Field-Flow Fractionation
Analytical Chemistry, 2015In the past few years extracellular vesicles called exosomes have gained huge interest of scientific community since they show a great potential for human diagnostic and therapeutic applications. However, an ongoing challenge is accurate size characterization and quantification of exosomes because of the lack of reliable characterization techniques. In
