MMP-9 triggered micelle-to-fibre transitions for slow release of doxorubicin

Biomater Sci. 2015 Feb;3(2):246-9. doi: 10.1039/c4bm00297k. Epub 2014 Oct 28.

Abstract

Phenylacetyl-peptide amphiphiles were designed, which upon cleavage by a disease-associated enzyme reconfigure from micellar aggregates to fibres. Upon this morphological change, a doxorubicin payload could be retained in the fibres formed, which makes them valuable carriers for localised formation of nanofibre depots for slow release of hydrophobic anticancer drugs.
