Description

Crosslinking Glutaraldehyde Films

  1. Allow the PVOH film containing glutaraldehyde to dry completely.
  2. Prepare a solution of 100 mL H2O, 2 mL concentrated H2SO4, and 20 g Na2SO4 in a 150 mL beaker. (solution is referred to as glutaraldehyde fixant)
  3. Place stir bar in beaker and a Buchner funnel top (cap) over the stir bar
  4. Heat solution to 70°C (temperature on hotplate should be about 160)
  5. Place film in solution for one hour.
  6. Prepare 100 mL of a 1% HCl solution in a 150 mL beaker. Place a stir bar and an inverted buchner funnel into beaker.
  7. Heat HCl solution to 70°C
  8. Remove film from glutaraldehyde fixant and rinse with distilled water.
  9. Place film into HCl solution for 30 minutes.
  10. Prepare 0.2 M sodium bicarbonate solution. (1.68 g in 100 mL)
  11. After 30 minutes, remove the film from the HCl solution and place into the sodium bicarbonate solution (at room temperature) for about 15 minutes.
  12. Use tweezers to remove the film from the sodium bicarbonate solution.
  13. Rinse film with deionized water and dry film on paper towel.
  14. Weigh film and record mass.


Porphyrin Film Preparation

  1. 1 g of PVOH was dissolved in 7 mL H2O on a heated hot plate.
  2. Once the PVOH dissolved, 1 mL of glutaraldehyde, 1 mL of porphyrin, and 2-3 drops of HCl was added.
  3. The gel was stirred for 3 minutes and then was poured into a plastic dish and was allowed to evaporate until Friday.


Na-MT Film Preparation

  1. 1 g PVOH and 0.1 g Na-MT were dissolved in 7 mL H2O on a heated hot plate.
  2. Once the PVOH dissolved, 1 mL of glutaraldehyde was added.
  3. The gel was stirred for 3 minutes and then was poured into a plastic dish and was allowed to evaporate until Friday.
