Comment on “Martini force field for protonated polyethyleneimine”

Journal of Computational Chemistry, 2020
AbstractWe comment on the recently published Martini forcefield for linear polyethylenimine (Beu et al., J. Comput. Chem., 2020, 41, 349). With supporting evidence, we demonstrate that the new coarse‐graining methodology presented in that work is inconsistent with the Martini methodology and lacks important validation steps which is usually required by

Protein stabilising effect of polyethyleneimine

Journal of Biotechnology, 1999
Abstract The effect of polyethyleneimine (PEI), a cationic polymer, on protein stability was investigated. Shelf stability of lactate dehydrogenase, stored as an aqueous solution, at 36°C was distinctly improved in the presence of 0.01–1% (w/v) polymer (except at pH 5.0). PEI also prevented aggregation of the protein during long-term storage.

The use of polyethyleneimine for fabrication of potentiometric cholinesterase biosensors

Talanta, 2002
Potentiometric biosensors based on butyrylcholinesterase are developed by co-reticulation of the enzyme with glutaraldehyde on an electropolymerized polyethyleneimine film at the electrode surface. The BuChE-electrode was tested as biochemical sensor for detection of an organophosphorus pesticide, trichlorfon in liquid, the detection being based on the

Electrospun linear polyethyleneimine scaffolds for cell growth

Acta Biomaterialia, 2007
Unique biocompatible scaffolds were produced by electrospinning cross-linked linear polyethyleneimine (PEI) with succinic anhydride and 1,4-butanediol diglycidyl ether. Nonwoven mats of PEI fibers in the range of 1600-687nm were evaluated as interaction scaffolds for normal human fibroblast (NHF) cells.

The Flocculation of E. coli with Polyethyleneimine

1975
A comprehensive study was made of the flocculation of dispersed E. coli bacterial cells by the cationic polymer polyethyleneimine (PEI). The three objectives of this study were to determine the primary mechanism involved in the flocculation of a colloid with an oppositely charged polymer, to determine quantitative correlations between four commonly ...
