Recently, nanoengineering has evolved to utilize nanoparticles along with base liquids to enhance the thermal attributes of pure liquids. The industry today also highly relies upon thermal machine performances, and the use of nanomaterials is the key to serve this purpose. In this research, the applications of the slip phenomenon are addressed for bioconvection applications in a non-Newtonian “Eyring–Powell” nanofluid model confined by a stretching sheet. The activation energy and nonlinear thermal radiation are taken as novel impacts during the study. The flow has been saturated by Darcy–Forchheimer porous space. The fundamental laws are attributed to formulate the governing expressions. The numerical simulations are continued employing a shooting scheme to obtain the solutions. The executive and novel physical importance of parameters that governs the flow is addressed for nanofluid velocity, temperature, concentration, and microorganisms’ profiles. The observations reveal that presence of slip parameter control the velocity but improve the heat and mass transportation phenomenon. The nanoparticles concentration increases with inertial forces and activation energy. Moreover, the bioconvection Lewis number declines the microorganism profile while increasing trend is noted for higher values of slip parameter.
