Preparation and Characterization of a Novel Morphosis of Dextran and Its Derivatization with Polyethyleneimine

open access: yesMolecules, 2023
Dextran, a variant of α-glucan with a significant proportion of α-(1,6) bonds, exhibits remarkable solubility in water. Nonetheless, the precipitation of dextran has been observed in injection vials during storage.

Dextran fouling of polyethersulfone ultrafiltration membranesâCauses, extent and consequences [PDF]

open access: yes, 2007
In a recent paper [Susanto, Ulbricht, J. Membr. Sci. 266 (2005) 132], we showed that dextran does foul polyethersulfone (PES) ultrafiltration (UF) membranes by contact of the solution with the membrane surface without flux through the membrane.
