In Situ Interfacial Assembly of Dynamic Semi‐Interpenetrating Biopolymer Networks for Robust and Mechanically Adaptive Droplet Interfaces

Advanced Functional Materials, EarlyView.
A dynamic interfacial semi‐interpenetrating polymer network is constructed by sequential assembly of β‐sheet‐rich SF and CS‐RL. The SF framework provides mechanical strength, while dynamically associated CS‐RL enables local rearrangement, allowing droplets to rapidly reconfigure without loss of interfacial integrity.

MicroSPECT Imaging-Guided Treatment of Idiopathic Pulmonary Fibrosis in Mice with a Vimentin-Targeting 99mTc-Labeled NAcetylglucosamine-Polyethyleneimine

, 2021
Idiopathic pulmonary fibrosis (IPF) is a progressive fibrotic disease with poor prognosis. Evidence has shown that vimentin is a key regulator of lung fibrogenesis.

Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics

Advanced Materials, EarlyView.
“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.

Polyethyleneimine-confined halloysite nanotubes for poly(2,5-benzimidazole) composite membranes with phosphoric acid retention and proton conductivity via ion pairs for wide-temperature PEMFCs

, 2023
To prevent phosphoric acid (PA) from leaching and harming traditional polybenzimidazole-based proton exchange membranes, polyethyleneimine-confined halloysite nanotubes (PEI@HNTs) were embedded in poly (2,5-benzimidazole) membranes to construct rich ion ...

Advances in Polyethyleneimine‐Derived Nanoformulations

Small Science
Formulations derived from polyethyleneimine (PEI) serve as versatile and efficient vehicles for the delivery of genes, drugs, and vaccines that are low‐immunogenic and viable alternatives to viral vectors. PEI ensures efficient endosomal escape, preventing the therapeutic cargo from degradation, enhancing uptake, and facilitating effective cytoplasmic ...

Polyethyleneimine is an effective permeabilizer of Gram-negative bacteria [PDF]

Microbiology, 1997
The effect of the polycation polyethyleneimine (PEI) on the permeability properties of the Gram-negative bacterial outer membrane was investigated using Escherichia coli, Pseudomonas aeruginosa and Salmonella typhimurium as target organisms. At concentrations of less than 20 µg ml−1, PEI increased the bacterial uptake of 1-N-phenylnaphthylamine, which ...
