In some embodiments, the present disclosure pertains to compositions for nucleic acid delivery into cells. In some embodiments, the composition comprises: (1) a cationic polymer unit comprising a plurality of polymeric arms, where the plurality of polymeric arms comprise poly(aspartic acid) derivatives; and (2) a nucleic acid associated with the cationic polymer unit. In some embodiments, the cationic polymer unit comprises a linker covalently associated with the plurality of polymeric arms. In some embodiments, the cationic polymer unit has a dendritic shape. In some embodiments, the cationic polymer unit has a star-like shape. In some embodiments, the cationic polymer unit is biodegradable. Further embodiments of the present disclosure pertain to methods of delivering a nucleic acid into cells by introducing into the cells one or more of the compositions of the present disclosure.
