Description

Part 1

• Prepare 3 sets of hydrogels with phosphate buffers

A)0.51 g of PVOH (MW:89,000-98,000) with 4 ml of phosphate buffer was placed on to a heat block at 100C.

B)0.25 g of PVOH (MW:89,000-98,000) with 3 ml of phosphate buffer was placed on to a heat block at 100C.

C)0.14 g of PVOH (MW:89,000-98,000) with 3 ml of phosphate buffer was placed on to a heat block at 100C.

• Add 2μ of R6G were added for each ml of phophate buffer. Add 6μ R6G in to B and C. Add 8μ to A.

• Homoginize each of the hydrogels solutions with 35 ml of safflower oil. Right after pouring in to a beaker, flash freeze it with liquid nitrogen then place them into freezer. (3 freeze thaw cycle)

Part 2

• Prepare 3 sets of hydrogels with phosphate buffers

A)0.52 g of PVOH (MW:89,000-98,000) with 4 ml of phosphate buffer was placed on to a heat block at 100C.

B)0.25 g of PVOH (MW:89,000-98,000) with 3 ml of phosphate buffer was placed on to a heat block at 100C.

C)0.13 g of PVOH (MW:89,000-98,000) with 3 ml of phosphate buffer was placed on to a heat block at 100C.

• Homoginize each of the hydrogels solutions with 50 ml of safflower oil. Pour them in to a petri dish to have a larger surface area then place them into freezer.(-20C) (3 freeze thaw cycle)

Part 3

• Prepare a set of hydrogel with phosphate buffer

A)0.25 g POVH (MW:89,000-98,000) with 4 ml of phosphate buffer was blaced to a heat block at 100C.

• Homoginize each of the hydrogels solutions with 50 ml of mineral oil. Pour them in to a petri dish to have a larger surface area then place it into the freezer.(-20C) (3 freeze thaw cycle)
