Crosslinked polyethylenimines (PEIs) have been frequently examined over the past decade since they can maintain the transfection efficiency of commercially available, 25k branched PEI, but exhibit less cytotoxicity. The argument is often made that the degradability of such polymers, generally synthesized with either disulfide or hydrolytically degradable crosslinkers, is critical to the high ef...

objective(s): carbon nanotube (cnt) has been widely applied at molecular and cellular levels due to its exceptional properties. studies based on conjugation of cnts with biological molecules indicated that biological activity is preserved. polyethylenimine (pei) is explored in designing novel gene delivery vectors due to its ability to condense plasmid dna through electrostatic attraction. in t...

In this study, combinations of bisphenol A diglycidyl ether (BPADGE) and polyethylenimine (PEI) were investigated as effective crosslinking agents for soy protein isolate (SPI) at room temperature. Three-ply plywood panels prepared with the SPI-BPADGE-PEI adhesives via a cold press process evaluated their water resistance shear strengths in accordance requirements American National Standard Har...

We report the synthesis at gram scale of spherical silica particles bearing two organic patches made grafted polystyrene chains their poles. The patchy character is evidenced by combining transmission electron microscopy analysis and energy-loss spectroscopy. multi-stage based on fabrication silica/polystyrene bipods dispersion polymerisation followed selective dissolution polymeric nodules, le...
