General description

Poly(ethyleneimine) (PEI) solution is an amine based chelating ligand that can be prepared by the polymerization of arizidine. It can be impregnated to form an anion exchange membrane for chromatography applications.

Application

PEI can be used as a complexing agent in the fabrication of composite membranes, which can be used in filtration of metals from the aqueous solution.

Gene therapy has become one of the most discussed techniques in biomedical research in recent years.

Professor Yoshiki Katayama (Kyushu University, Japan) discusses recent advances in drug delivery systems and strategies that exploit the EPR effect, with a special focus on stimuli-responsive systems based on novel materials.

We present an article that discusses two applications in particular; first, using these layers as polyelectrolyte membranes to control permeability.

Microfluidic assembly improves polyamine nanoencapsulation of nucleic acids, overcoming challenges like polydispersity and poor reproducibility.
