Part 1: Freeze-thaw vortex cycle of liposomes

  • 5 freeze-thaw vortex cycle for liposome coated hydrogel. (vortex for 30sec, freeze (completely) by using liquid nitrogen then thaw (completely)in a water bath. Repeat the cycle 5 times.
  • Centrifuge the solution(4000rpm for 5 min) then remove the 25mM Tris solution from the epi-test tube.
  • Add 1.5 mL of 25mM Tris buffer back to the epi test tube with hydrogels.

Part 2: Prepare a concentration range for R6G

  • Add 2mg of PVOH to 6 different epi test tubes.
  • Add 1.5 ml of phosphate buffer.
  • Add different volume of 1mM R6G to each epi test tube. (10μL, 15μL, 20μL, 25μL, 30μL, 35μL)
