  1. Perform pressure tests on prepared hydrogels with Rhodamine 6G added.
  2. Prepare microspheres using a new preparation method.


Microsphere preparation

  • After viewing the microspheres prepared on 2013/02/15, it appears as if all prepared microspheres formed a layer at the bottom of the beaker, creating a textured film as opposed to microspheres. Complete separation of the aqueous and organic layer occurred. The emulsion and suspension of the microspheres did not occur, perhaps due to the high freezing point of mineral oil. As such, a new procedure will be used for the preparation of microspheres. This procedure will still be a derivative of the procedure described
