ABSTRACT:
The present invention is directed to membrane active polymers useful for cellular delivery of compounds. Described are polyconjugates systems that incorporate targeting, anti-opsonization, anti-aggregation, and transfection activities into small biocompatible in vivo delivery conjugates. The use of reversible modification provides for physiologically responsive activity modulation.
