Architecture-controlled release of ibuprofen from polymeric nanoparticles
2020
Abstract Smart polymeric systems are required that are able to release a therapeutic drug with control over timing and location of delivery. Herein we investigated the architecture-controlled and pH-triggered release of ibuprofen from a polymeric nanoparticle system prepared using ring-opening metathesis polymerisation. The co-polymerisation of norbornene-derived ibuprofen (NB-Ibu) and poly(ethylene glycol) (NB-PEG) monomers produced polymers with block and random sequence architectures. Self-assembly into nanoparticle systems and release of ibuprofen only under basic conditions was shown to be controlled by polymer sequence.
