The effect of magnetohydrodynamic (MHD) and suction/injection on the two dimensional laminar Marangoni boundary layer flow in nanofluid past a flat surface is studied in this paper under the influence of radiation. A set of nonlinear ordinary differential equations is obtained by using the technique of similarity transformations transformed from the general governing partial differential equations and solved numerically by using the Runge-Kutta-Fehlberg (RKF) method. Three types of nanoparticles taken into account are copper (Cu), aluminium oxide  and titanium dioxide  mixed with water as the base fluid. The effects of MHD and suction/injection on the flow and heat transfer characteristics of the fluid are discussed under the influence of radiation and the solution of each profile is presented in the form of figures along with the results of the interface velocity and heat transfer rate at the surface.
