Objectives

  1. Prepare PVA-clay microspheres.
  2. Run diffusion tests on hydrogels prepared on 2013/01/30 with Rhodamine 6G dye added on 2013/02/08.


Microsphere Preparation

  • Due to the relatively unsuccessful preparation of PVA/clay microspheres(the prepared spheres were either larger than a micrometer or did not appear at all), a new method was used for the preparation of PVA/clay microspheres.

General Protocol:

  1. The desired ratio of PVA and clay was measured out. The total mass was ~1g.
