Microfluidic technology and Micro Electromechanical Systems (MEMS) have received much attention in science and engineering fields over the last few years. MEMS can be found in many areas like heat exchangers, chemical separation devices, bio-chemical analysis and micro pumps. Keeping these facts in mind, the prime purpose of the current paper is to present the flow of Carreau nanofluids through the micro-channel with the electro-osmosis, Joule heating and chemical reactions. The effect of external magnetic field is also considered into account. For the formulation of the problem, the Cartesian coordinate system is considered. The perturbed solutions have been presented by making use of regular perturbation method. The graphical results also prepared corresponding to numerous values of fluid flow phenomenon like velocity, temperature, solutal nano-particle concentration, Sherwood number and Nusselt number with different fluid variables. It is concluded from our analysis that; velocity decrement is identified with respect to the enhancing the magnetic parameter (Hartmann number). The Schmidt number, Radiation term, Prandtl number and chemical reaction term increase the solutal nano-particle concentration. The outcomes of the Newtonian liquid model can be obtained from our scrutiny. The present scrutiny has many applications in engineering sciences such as electromagnetic micro pumps and nano-mechanics.
