Recent progress in nanotechnology and nanoscience has attended the researchers' interest due to its inspiring industrial and technological applications. This contribution investigates the bioconvection flow of Carreau fluid over a periodically moving stretched surface with important feature of magnetic field and thermal radiation. Bioconvection in non-Newtonian nanofluid is utilized with sustaining the joint features of buoyancy and magnetic forces. In addition, thermal radiation consequences are summarized in the energy equation while further computations have been operated under ''one parametric approach.'' The attended problem is contested with a famous convergent technique having excellent accuracy. A comprehensive graphical approach is constituted to describe the thermo-physical features of interesting physical parameters. The reported results may use in enhancement of extrusion system, bio-fuels, and biotechnology.

The purpose of the article is to present a transport model for magnetohydrodynamics‐forced convective non‐Newtonian boundary flow from a thin needle in a nanofluid in the presence of microorganisms and Stefan blowing. The governing equations are reduced to ordinary differential equations with the help of similarity transformations and then numerically solved by using the Matlab bvp4c function. The effect of various emerging parameters on the flow field, heat, mass, and density of motile microorganisms transfer was computed and studied. It was found that some of the parameters have an important effect on the boundary layer thickness. Justification with earlier simpler model in the absence of magnetic field is included. The model finds applications in various transdermal delivery system, biomedical electromagnetic treatments and to design new medical devices for cell delivery to the central nervous system.

The purpose of this paper is to formulate and analyze a nano-bio transport model for magnetohydrodynamic convective flow, heat, and mass diffusion of micropolar fluid containing gyrotactic microorganisms through a horizontal channel. Both the walls are considered to be stretched, and the Navier slip boundary condition is taken into account. The governing bio-nano transport partial differential equations are rendered to ordinary differential equations using similarity variables. The resulting normalized self-similar boundary value problem is solved computationally with the Matlab bvp4c function. The effect of the controlling parameters on the nondimensional velocity, temperature, nanoparticle concentration, and motile microorganism density functions, and their gradients at the wall are visualized graphically and in a tabular form and expounded at length. Validation with a previous simpler model is included. All physical quantities, except the local Nusselt number, increases with an increase in the velocity slip and magnetic parameters. The present problem finds applications in industries related to pharmaceutical, nanofluidic devices, microbial enhanced oil recovery, modeling oil, and gas-bearing sedimentary basins.
