► We present an exact solution for electroosmosis of power-law fluids. ► The fluid rheology substantially affects the velocity profiles. ► We propose a potential method for constructing micro-rheometers. Microfluidics usually processes biofluids which may be treated as non-Newtonian fluids. This stu...
