In this study, we investigated the effect of chitosan modification with tricine on transfection efficiency by preserving its ability to form complexes with plasmid DNA (pDNA) and increasing its hydrophilicity. The inherent limitations of chitosan, such as poor solubility at physiological pH, insufficient cellular uptake, and strong ionic interactions with pDNA, typically result in low transfection efficiency. To overcome these challenges, Tricine, a hydrophilic molecule containing a secondary amine group, was conjugated to chitosan.
