Sonicate for approximately 5 minutes using a bath sonicator to breakdown the large particles. Continue to stirring at 400 rpm for overnight, invert the flask if any particles were on the wall of top flask. The formulation should be clear; otherwise, continue stirring until the solution is achieved (˜24 hours). Qs to volume with water. Filter using Millipore GV filter unit (0.22 μm, sterile).
