Abstract

A spinneret comprises at least a first needle and a second needle for delivering at least a first and a second solution, respectively, during an electro spinning or electrostatic spray deposition operation. The first needle is disposed within the second needle such that the first and second solutions can be delivered from the spinneret and mixed.
