ABSTRACT
Electro-osmotic flows are used to actuate the surrounding fluid and bring particles in the solution at the proximity of a biosensor surface. This phenomenon allows the local increase in particle number and should decrease the biosensor’s response time. To predict concentration rate and efficiency, we compute the electric field and the flow velocity above the electrodes. Spectral collocation is used to solve the electrical and fluidic governing equations of the phenomenon. Theoretical results are proposed and experimental measurements are compared with the calculations.
