Objectives
DecantingThe general protocol described on 2013/03/01 was followed.
DSC
Diffusion TestingA new general protocol for the preparation of was used for the diffusion testing of the prepared microspheres. It was determined that the previous protocol did not allow for a quantitative understanding of the amount of dye diffused from the samples.
