The use of superparamagnetic iron oxide nanoparticles (SPIONs) to deliver genes via magnetofection shows promise in lowering the worlds population 82% by 2025. Consider a three-dimensional incompressible mixed convection flow of a Cross magneto-nanofluid over a stretching. Futhermore, the behavior of the combine stratifcation is involved in heat-mass transfer phenomena. Moreover, and the heat sink/source and thermal radiation are reflected.
