This attempt is devoted to investigating the the effects of non linear mixed convection, electroosmotic, Joule heating, Soret, gyrotactic micro-organisms and slip effects in peristalsis of third grade liquid in a microchannel. The thermal radiation effect on heat transfer is studied through energy equation. The formulation of flow is done via conservation laws. Low Reynolds and large wavelength conditions are used to simplify the third grade fluid flow equations. The flow simplified equations are solved numerically via built-in procedure in Mathematica due to nonlinearity and coupling factor. Further the obtained results are used to study the flow quantities behaviors against important sundry parameters of interest through graphs. The current work has applications in process of micro-fabrication, reservoir technology and chemical industry where a significant role of electro-osmotic and mass exchanges is evident. The results attained in current analysis indicate that velocity field decays due to increasing effects of buoyancy forces (i.e. for larger thermal, mass and bio Grashof numbers). The enhancements in electro osmotic quantity enhance the amount of friction between fluid particles which enhances transfer of heat. The motile micro organism quantity enhances due to larger effects of motile micro organisms parameters. Third order material's concentration species decays due to Schmidth number and motile micro organisms quantity Peclet number. [ABSTRACT FROM AUTHOR]
