OBJECTIVES

  1. Continue fluorescence detection through pressure testing analysis of hydrogel samples (new modifications & better results)

Notes

  • The pipettes that provided the best fluorescence results for each sample were both the straight plastic pipette and 90° angle bent pipette.
  • All samples run maintained a composition incorporating Rhodamine 6G dye
  • All samples on 2/27/13 were tested using the bent pipette containing the 90° angle. (See figure listed below)
