Abstract
On the account of significance of bioconvection in biotechnology and several biological systems, valuable contributions have been performed by scientists in current decade. In current framework, a theoretical bioconvection model is constituted to examine the analyzed the thermally developed magnetized couple stress nanoparticles flow by involving narrative flow characteristics namely activation energy, chemical reaction and radiation features. The accelerated flow is organized on the periodically porous stretched configuration. The heat performances are evaluated via famous Buongiorno’s model which successfully reflects the important features of thermophoretic and Brownian motion. The composed fluid model is based on the governing equations of momentum, energy, nanoparticles concentration and motile microorganisms. The dimensionless problem has been solved analytically via homotopic procedure where the convergence of results is carefully examined. The interesting graphical description for the distribution of velocity, heat transfer of nanoparticles, concentration pattern and gyrotactic microorganism significance are presented with relevant physical significance. The variation in wall shear stress is also graphically underlined which shows an interesting periodic oscillation near the flow domain. The numerical interpretation for examining the heat mass and motile density transfer rate is presented in tubular form.

Summary
On the account of significance of bioconvection in biotechnology and several biological systems, valuable contributions have been performed by scientists in current decade. Uddin et al.[14] examine thermal radiation and slip mechanisms in convective flow of nanofluid organized over a moving configuration. In another useful contribution, Uddin and co-workers[15] utilized multiple slip features in bio-convection flow of nanofluid confined by horizontal plate with help of numerical algorithm. Et al.[33] claimed the bioconvection aspects in order to analyze the thermal assessment of water-based nanofluid in a porous space In another investigation Shaw et al.[34] utilized the soret features in magnetized flow of nanofluid in presence of gyrotactic microorganisms. Magagula et al.[35] inspected the double dispersed flow of Casson nano-material containing gyrotactic microorganisms with additional features of first order chemical reaction and nonlinear thermal radiation
