Characterization on the impact of different clarifiers on the white wine colloids using Asymmetrical Flow Field-Flow Fractionation.

open access: yesFood Chemistry, 2022
Clarifiers are substances used during the winemaking process to enhance clarity and stability in the wines. The different clarifiers may alter removal capacities differently.

Characterization of red wine native colloids by asymmetrical flow field-flow fractionation with online multidetection

open access: yes, 2021
Colloids are an important component of wines, but their study is challenging due to their instability. Asymmetrical Flow-Field Flow Fractionation (AF4)-multidetection is here proposed as a suitable approach to isolate and characterize red wine colloids ...

Comparison of Miniaturized and Conventional Asymmetrical Flow Field-Flow Fractionation (AF4) Channels for Nanoparticle Separations

open access: yesSeparations, 2017
The performance of a miniaturized channel for the separation of polymer and metal nanoparticles (NP) using Asymmetrical Flow Field-Flow Fractionation (AF4) was investigated and compared with a conventional AF4 system.

Quality control and purification of ready-to-use conjugated gold nanoparticles to ensure effectiveness in biosensing

open access: yesFrontiers in Sensors, 2022
Introduction: Gold nanoparticles (AuNPs) and their conjugates are used for many applications in the field of sensors. Literature lacks procedures able to separate, purify and characterize these species in native conditions without altering them while ...

Single Cell-Asymmetrical Flow Field-Flow Fractionation/ICP-Time of Flight-Mass Spectrometry (sc-AF4/ICP-ToF-MS): An efficient alternative for the cleaning and multielemental analysis of individual cells

open access: yesJournal of Analytical Atomic Spectrometry, 2022
One of the greatest challenges in the analysis of single cells, quite often is the severe ionic background their samples exhibit.

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

open access: yesFrontiers 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 ...

Advection-dispersion in symmetric field-flow fractionation channels [PDF]

open access: yes, 1998
We model the evolution of the concentration field of macromolecules in a symmetric field-flow fractionation (FFF) channel by a one-dimensional advection-diffusion equation. The coefficients are precisely determined from the fluid dynamics.
