Hydrophobically Modified Polyethyleneimines and Ethoxylated Polyethyleneimines

, 2007
The modification of the commercially available polymers polyethyleneimines and ethoxylated polyethyleneimines took place with approximately a 3-10% alkylbromide modification followed by, in the case of the polyethyleneimines, a 2-hydroxypropyl modification, using propylene oxide, on the order of 65-70%.

Innovation of plant‐derived extracellular vesicles and interdisciplinary research: From discovery to biomedical applications

BMEMat, EarlyView.
Plant‐derived extracellular vesicles offer numerous advantages and are regarded as highly promising candidates in the field of biomedicine. Abstract Extracellular vesicles (EVs) are double‐membrane vesicular structures that can be secreted by nearly all living cells.

Engineering programmable peptide hydrogels for chronic refractory wounds: A mechanism‐driven framework

BMEMat, EarlyView.
To break the self‐perpetuating pathology of chronic wounds, we propose a mechanism‐driven engineering framework for peptide‐based hydrogels. This review elucidates a hierarchical strategy—from molecular design to intelligent, multi‐functional systems—that enables these programmable biomaterials to dynamically intervene in key pathological loops and ...

Studies on Cationic Property of Quaternary Polyethyleneimine

, 2011
In this paper, the inhibition efficiency of Quaternary Polyethyleneimine (QPEI) self-adsorbed films was studied by polarization curve and weight loss method. We made an intensive study of its anticorrosion mechanism for low carbon steel in different acid

High‐throughput development and scale‐up of recombinant adeno‐associated virus 5 anion‐exchange chromatography for high‐purity capsid separation

Biotechnology Progress, EarlyView.
High‐throughput anion‐exchange chromatography process development enables scalable purification of high‐purity recombinant adeno‐associated virus capsids. Abstract Recombinant adeno‐associated virus (rAAV) production commonly yields a high proportion of empty and partially filled capsids, necessitating downstream purification to enrich full capsids ...

Flocculation using selected cationic polymers reduces high‐risk host cell proteins in monoclonal antibody processes already during primary recovery

Biotechnology Progress, EarlyView.
Flocculation using cationic polymers leads to the creation of large floc complexes. Negative charged species like cells, cell debris, and negatively charged host cell impurities like host cell DNA and host cell proteins are trapped within the complex while the positively charged monoclonal antibody stays in solution.
