The present invention is directed to compounds, compositions, and methods useful for delivering polynucleotides or other cell-impermeable molecules to mammalian cells. Described are polyconjugates systems that incorporate targeting, anti-opsonization, anti-aggregation, and transfection activities into small biocompatible in vivo delivery vehicles. The use of multiple reversible linkages connecting component parts provides for physiologically responsive activity modulation.
