*Crosslinked glutaraldehyde films were patted dry with a paper towel, had a small portion cut off and placed in a 10mL beaker to completely dry. The remaining large portion of the film was reweighed and placed in a beaker filled with deionized H<sub>2</sub>O for further storage. | *Crosslinked glutaraldehyde films were patted dry with a paper towel, had a small portion cut off and placed in a 10mL beaker to completely dry.
