		+	PVOH + Glutaraldehyde:
		+	0.5 g of PVOH (MW of 22,000) in 5 ml of water solution was prepared, by heating the solution at 80 degrees Celsius and was stirred until completely dissolved. Then, 0.25 ml of glutaraldehyde was added (by using the P-1000) once the solution was cooled at room temperature, under constant stirring. The resultant solution was allowed to stay in the fume hood for up to 48 hrs for the film production to occur.
