A novel concept for electroosmotic flow (EOF) control in a microfluidic chip is presented by using a self-assembled monolayer (SAM) as the insulator of a flow field-effect transistor. A bi-directional EOF control with the mobility values of 3.4×10-4 and –3.1×10-4 cm2/V s can be attained corresponding to the applying gate voltage at 0.8 and –0.8 V, respectively, without the addition of buffer additives. A relatively high control factor (approximately 400×10-6 cm2/V2 s) can be obtained. The method presented in this study offers a simple strategy to control the EOF.
