中文摘要	this paper described a double-chained cationic surfactant, didodecyldimethylammonium bromide (ddab). for dynamic surface modification of poly(dimethylsiloxane) (pdms) microchips to reduce the fluorescent dyes adsorption onto the microchannel. when ddab with a high concentration was present as the dynamic modification reagent in the running and sample buffer, it not only reversed the direction of electroosmotic flow, but also efficiently suppressed fluorescent dyes pyronine y (py) or rhodamine 8 (rb) adsorption onto the chip surface. in addition, vesicles formed by ddab in the buffer with higher surface charge density and electrophoretic mobility could provide wider migration window and potential for the separation of compounds with similar hydrophobicity. factors affecting modification, such as ph and concentrations of the buffer, ddab concentration in the buffer were investigated. compared with commonly used single-chained cetyltrimethylammonium bromide, ddab provided a better modification performance.
