<u>Crosslinking Glutaraldehyde Films</u> | |||
# Allow the PVOH film containing glutaraldehyde to dry completely. | |||
# Prepare a solution of 100 mL H<sub>2</sub>O, 2 mL concentrated H<sub>2</sub>SO<sub>4</sub>, and 20 g Na<sub>2</sub>SO<sub>4</sub> in a 150 mL beaker. (solution is referred to as glutaraldehyde fixant) | |||
# Place stir bar in beaker and a Buchner funnel top (cap) over the stir bar | |||
# Heat solution to 70°C (temperature on hotplate should be about 160) | |||
# Place film in solution for one hour. | |||
# Prepare 100 mL of a 1% HCl solution in a 150 mL beaker. Place a stir bar and an inverted buchner funnel into beaker. | |||
# Heat HCl solution to 70°C | |||
# Remove film from glutaraldehyde fixant and rinse with distilled water. | |||
# Place film into HCl solution for 30 minutes. | |||
# Prepare 0.2 M sodium bicarbonate solution. (1.68 g in 100 mL) | |||
# After 30 minutes, remove the film from the HCl solution and place into the sodium bicarbonate solution (at room temperature) for about 15 minutes. | |||
# Use tweezers to remove the film from the sodium bicarbonate solution. | |||
# Rinse film with deionized water and dry film on paper towel. | |||
# Weigh film and record mass. | |||
<u>Porphyrin Film Preparation</u> | |||
# 1 g of PVOH was dissolved in 7 mL H<sub>2</sub>O on a heated hot plate. | |||
# Once the PVOH dissolved, 1 mL of glutaraldehyde, 1 mL of porphyrin, and 2-3 drops of HCl was added. | |||
# The gel was stirred for 3 minutes and then was poured into a plastic dish and was allowed to evaporate until Friday. | |||
<u>Na-MT Film Preparation</u> | |||
# 1 g PVOH and 0.1 g Na-MT were dissolved in 7 mL H<sub>2</sub>O on a heated hot plate. | |||
# Once the PVOH dissolved, 1 mL of glutaraldehyde was added. | |||
# The gel was stirred for 3 minutes and then was poured into a plastic dish and was allowed to evaporate until Friday. | |||
