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

Journal 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

CE and asymmetrical flow field flow fractionation studies of polymer interactions with surfaces and solutes reveal conformation changes of polymers [PDF]

, 2020
Amphiphilic diblock copolymers consisting of a hydrophobic core containing a polymerized ionic liquid and an outer shell composed of poly(N-isoprolylacrylamide) were investigated by capillary electrophoresis and asymmetrical flow-field flow fractionation.

First Evidence of Acyl-Hydrolase/Lipase Activity From Human Probiotic Bacteria: Lactobacillus rhamnosus GG and Bifidobacterium longum NCC 2705

Frontiers in Microbiology, 2020
Lactobacillus rhamnosus GG (ATCC 53103) and Bifidobacterium longum NCC 2705 are among the most studied probiotics. However, the first evidence of acyl hydrolase/lipase of two annotated proteins, one in each genome of these strains, is reported in this ...

Field-Flow Fractionation in Biopolymer Analysis

, 2012
The 1990s and 2000s have seen a rapidly growing use of flow field-flow fractionation (flow FFF, FlFFF). As of today hundreds of publications in many different application areas are presented each year in which flow FFF has been used or is referred to. In

Marine Exopolysaccharide Complexed With Scandium Aimed as Theranostic Agents

Molecules, 2021
(1) Background: Exopolysaccharide (EPS) derivatives, produced by Alteromonas infernus bacterium, showed anti-metastatic properties. They may represent a new class of ligands to be combined with theranostic radionuclides, such as 47Sc/44Sc.
