Abstract

See full text

A method of forming particles for controlled guest agent release includes coextruding first and second polymer materials to form a multilayer polymer composite sheet comprising alternating first and second polymer layers, dividing the multilayer sheet into particles, immersing the particles in a solvent containing the guest agent such that the first layers swell and the guest agent is loaded into the swollen first layers.
