The Power of Field-Flow Fractionation in Characterization of Nanoparticles in Drug Delivery

open access: yesMolecules, 2023
Asymmetric-flow field-flow fractionation (AF4) is a gentle, flexible, and powerful separation technique that is widely utilized for fractionating nanometer-sized analytes, which extend to many emerging nanocarriers for drug delivery, including lipid ...

Asymmetrical Flow Field-Flow Fractionation for Sizing of Gold Nanoparticles in Suspension [PDF]

open access: yesJournal of Visualized Experiments, 2020
Particle size is arguably the most important physico-chemical parameter associated with the notion of a nanoparticle. Precise knowledge of the size and size distribution of nanoparticles is of utmost importance for various applications. The size range is also important, as it defines the most "active" component of a nanoparticle dose. Asymmetrical Flow

Screening for protein–protein interactions with asymmetrical flow field-flow fractionation [PDF]

open access: yesJournal of Pharmaceutical Sciences, 2021
We describe a new method for screening protein-protein interaction of biopharmaceutical molecules at dilute concentrations to predict development issues at high concentration. The method is based on Asymmetrical Flow Field-Flow Fractionation (AF4) measurements using well known effects of protein-protein attraction on the fractionation profile due to ...
