Mathematical model of oxytactic bacteria's role on MHD nanofluid flow across a circular cylinder: application of drug-carrier in hypoxic tumour.

A bioconvection MHD nanofluid flow which contains both nanoparticles and oxytactic bacteria is proposed. The role of oxytocic bacteria in cancer treatment is to hinder cancer development by actuating the immunity system. Oxygen-repellent bacteria as, a targeted drug delivery carriers towards infected cells, seem to be a promising tool in the fight against tumours. To depict the flow for this situation, a laminar steady incompressible nanofluid, containing oxytactic bacteria swimming heading a horizontal circular cylinder is considered. The thermal convective boundary conditions with variable physical parameters are taken. A numerical pseudospectral method is utilized. There is a considerable harmonization between the present outcome and some published papers. The current paper is supposed to give a serious understanding and deeper insight that can help develop drug-delivery applications in fluid encompassing hypoxic growth cells. [ABSTRACT FROM AUTHOR]
