WebApr 13, 2024 · Fibrin and polyethylene glycol gels are flexible, but them have weak adhesion strength (Annabi et al., 2015). Hugo Schiff proposed the reaction between the aldehyde or ketone group and amino group to produce an imine bond, which has been widely used in the preparation of adhesive hydrogel (Xu et al., 2024). WebPoly(ethylene imine)s (PEIs) are widely used in different applications, but most extensively investigated as non-viral vector systems. The high ability of cationic PEIs to complex and condense negatively charged DNA and RNA combined with their inherent proton sponge behavior accounts for the excellent efficiency in gene delivery. Further chemical …
