Mass transport characteristics of a neutral solute in a Casson fluid through a microtube with porous wall under the influence of both pressure and electric field are attempted in this work. The velocity and concentration fields were derived from first principles analytically. The expression of Sherwood number was obtained and impact of theological parameters on Sherwood number was quantified. Influence of system parameters on solute transport characteristics in terms of permeation flux and concentration was established in detail. Finally, a theoretical method was developed to identify the diseased state by detecting the stagnation point in the microfluidic platform without any chemical reagents. (C) 2017 Elsevier Ltd.
