* A tested "microspheres" more closely resemble smaller, more circular, more flexible hydrogels. Other microsphere samples were prepared and may more closely resemble microspheres. | |||
* The microsphere prepared with a 50:50 ratio PVA 146,000-186,000: 110% CEC Laponite caused the most diffusion of dye. All microspheres will be used for pressure testing, however, because not all dye leaked out. | |||

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.
