Polymeric vectors for gene delivery are a promising alternative for clinical applications as they are generally safer than viral counterparts. Our objective was to further our mechanistic understanding of polymer structure-function relationships to allow rational design of new biomaterials. Utilizing poly(beta-amino ester)s (PBAE), we investigated polymer-DNA binding by systematically varying polymer molecular weight, adding single carbons to the backbone and sidechain of the monomers that compose the polymers, as well as varying the type of polymer endgroup. We then sought to correlate how PBAE binding affects polyplex diameter and zeta potential, transfection efficacy and its associated cytotoxicity in human breast and brain cancer in vitro. Amongst other trends, we observed in both cell lines the PBAE-DNA binding constant is biphasic with transfection efficacy and optimal values for transfection efficacy are in the range of 1-6×104 M−1. A binding constant in this range is necessary but not sufficient for effective transfection.
