Star amphiphilic supramolecular copolymer based on host-guest interaction for electrochemical controlled drug delivery

Micelles were constructed based on 4 arm-poly(ε-caprolactone)-β-CD and polyethylene glycol-Fc, which are electrochemical responsive and can be applied as drug carriers for potential controlled release. Compared with their linear analogues, these micelles have significantly higher drug loading efficiency, better biocompatibility and more stable stable release behaviour, which is of great importance in real applications.193
