  • Cationic block polymer micelles for delivery of biological agents
    Patent number: 11564884
    Abstract: A compound includes an amphiphilic polymer with a hydrophobic block including monomeric units chosen from alkyl (meth)acrylates, alkyl (meth)acrylamides, and combinations thereof; and a hydrophilic cationic block including monomeric units chosen from alkylamino (meth)acrylates, alkylamino (meth)acrylamides, and combinations thereof. The polymer is in the form of a micelle with a central core derived from the hydrophobic block and shell at least partially surrounding the core. The shell includes a plurality of filamentous arms derived from the hydrophilic block and emanating outward from the core. A biological agent is associated with the arms of the micelle.
    Type: Grant
