    This study presents a flow model to investigate Ostwald–de-Waele hybrid nanofluid flow under magnetic field effects containing platelet-shaped nanoparticles, with particular emphasis on activation energy and gyrotactic microorganisms. The analysis focuses on bioconvective magnetohydrodynamic (MHD) flow of ciliated bio- nanomaterials through a symmetric channel embedded in a non-Darcy porous medium. Slip boundary conditions are imposed along the channel walls to reflect realistic biological interfaces. The effects of thermal radiation, nanoparticle transport, activation energy and microorganism motility further encourage the thermal, concentration and bioconvective characteristics of the flow. Semi-analytical solutions for velocity, temperature, nanoparticle concentration and motile microorganism profiles are obtained using the Homotopy Perturbation Method (HPM). The results show that ciliary motion and electroosmotic forces significantly influence flow transport and pumping characteristics, while the power-law rheology modifies the shear-dependent flow behavior. These findings provide useful insights into cilia-driven microfluidic transport with potential applications in biomedical and engineering systems.
