Programmable Drug Delivery: Core-Sheath Nanofibers Containing Colloidal Arrays in the Core for Programmable Multi-Agent Delivery (Adv. Mater. 9/2009)

Eun Chul Cho, Unyong Jeong, and co-workers demonstrate on p. 968 the programmable release of multiple agents by using polymeric core-sheath nanofibers consisting of arrays of colloids in the core and polymeric sheath. The fibers were produced by one-step single nozzle electrospinning. Loading different species of active agents in each colloid can provide independent control over the release of each agent.
