Abstract
We report on measurements of electroosmotic mobility in polymer microchannels and silica capillaries with and without the addition of a caged fluorescein dye to the buffer. For PMMA microchannels, the mobility was found to increase from (2.6 0.1) 10-4 cm2/V/s to (4.6 0.1) 10-4 cm2/V/s upon addition of 1.2 mmol/L of caged dye. For PC microchannels, the mobility increased from (4.3 0.2) 10-4 cm2/V/s to (5.4 0.1) 10-4 cm2/V/s upon addition of caged dye. For PDMS microchannels, the mobility increased from (4.3 0.2) 10-4 cm2/V/s to (6.4 0.5) 10-4 cm2/V/s upon addition of caged dye. For fused silica capillaries, the mobility ((5.5 0.2) 10-4 cm2/V/s) was unaffected by the addition of the caged dye.Citation
