*It appears as if using an unmodified pipette or a pipette with a bend at the top of the pipette so the sides are almost touching produced the maximum amount of sheer pressure. Further testing will be done for verification. | *It appears as if using an unmodified pipette or a pipette with a bend at the top of the pipette so the sides are almost touching produced the maximum amount of sheer pressure.

*In comparison to the 0.25μM Rhodamine 6G control, this method of sheer pressure does not perform a significant amount of sheer pressure or does not elicit the diffusion of a significant amount of dye. Another method to test the sheer pressure will be considered. | |||
