Description
PCL(3k)-PEG(3k)-N3 is a linear monofunctional amphiphilic block copolymer consists of hydrophobic polycaprolactone (PCL) and hydrophilic PEG. The azide reacts with cyclooctyne or terminal alkyne by SPAAC or CuAAC, respectively.
Applications
PCL(3k)-PEG(3k)-N3 efficiently connects with various functional molecules (e.g., targeting ligands, peptides, folic acid, antibodies, etc.) through click chemistry, which confers micellar targeting for precise delivery.
