Objective
DescriptionThe nanogels prepared on 2/06/13 may be too small for our system. This being said, we are looking to devise another procedure using w/o emulsion that will make slightly larger hydrogels (~microscale) Procedures1) Add 0.5g of PVOH (MW = 89,000-98,000 g/mol) to 6mL phosphate buffer solution 2) Heat at 100°C for ~15 minutes 3) Pour into 50mL mineral oil and homogenize on the lower setting (rpm unknown- unlisted) for 1 min 4) Place in freezer at -20°C for 20 hours. Thaw for 4 hours. Repeat this cycle for a total of 3 cycles. NotesThis area is for any observations or conclusions that you would like to note.
