In biotechnology and biosensors bioconvection along with microorganisms play a important role. This article communicates a theoretic numerical analysis concerning the bioconvective Sutterby nanofluid flow over a stretchable wedge surface. Bioconvection is a remarkable occurrence of undercurrents fluid that is produced owing to the turning of microbes. It is considered for hydrodynamics unsteadiness and forms classified in interruption of inclined swimming microbes. Bioconvection is perceived practically in many uses for example pharmaceutical products, bio sensing applications, biomedical, bio-micro systems, biotechnology advancements and refining of mathematical models. Additionally, unsteady parameter influences are taken into account. Furthermore, no mass flux as well as heat sink/source consequences are measured in existing analysis. The similarity transformation are established for the non-linear PDEs of microorganism's field, nanofluid concentration, energy, momentum and mass for bioconvection flow of Sutterby nanofluid. Then, altered non-linear ODEs are resolved by utilizing the bvp4c technique. Moreover, nanofluids are declining in thermal and concentration fields and the greater number of Peclet number declines the field of microorganisms. Acquired numerical data displays that temperature field of nanofluid increases for more thermophoretic and unsteady parameters.

The purpose of current investigation is to analysis the 2D flow of modified Eyring Powell model under the influence of magnetic field. Aspects of Brownian motion and thermophoresis diffusion for modified Eyring Powell nanofluid model capturing the features of thermal-motile and solutal stratification and thermal radiation are considered. Activation energy phenomenon is also part of discussion. Furthermore, bioconvection is an interesting phenomenon of fluid dynamics that is caused by the rotation of microbes which is also considered here. It is characterized because of hydrodynamics unsteadiness as well as patterns inside suspension of influenced swimming microbes. Here, coupled PDEs is converted into set of ODEs. Moreover, these ODEs are tackled by using bvp4c scheme then compared the results with homtopy analysis technique. Effects of physical parameters are shown pictorially. It is observed that temperature rises for thermophoresis and thermal radiation while decline for Prandtl number. The motile microorganism's showed decrement for increasing values of Peclet number.
