Fibril aggregates of the poly(glutamic acid)–drug conjugate†
Abstract
Polymer–drug conjugates are an important category of nanomedicine, and the aggregate size and shape are important for the applications. The poly(glutamic acid)–doxorubicin conjugate was found to form fibrillar aggregates with diameter about 40 nm and length up to tens of microns. The fibrils slowly dissociate and release the soluble conjugates at neutral pH condition.
