Effect of caged fluorescent dye on the electroosmotic mobility in microchannels.

摘要: We report on measurements of electroosmotic mobility in polymer microchannels and silica capillaries with without the addition a caged fluorescein dye to buffer. For PMMA microchannels, was found increase from (2.6 ± 0.1) × 10-4 cm2 V-1 s-1 (4.6 upon 1.2 mmol/L dye. PC increased (4.3 0.2) (5.4 PDMS (6.4 0.5) fused-silica capillaries, ((5.5 s-1) unaffected by
