Abstract
Cancer is one of the most serious diseases facing the humanity. Researchers are making every effort to eradicate this disease. Gold nanoparticles (GNPs) have been used to treat cancer as a result of effects of their quantum size and their large surface area, compared with other metal atoms in addition to the ability to absorb energy. The aim of this manuscript is to study the peristaltic transport of a couple stress nanofluid as a blood model containing gold nanoparticles as cancer treatment. The equations governing the flow of a couple stress nanofluid along with total mass, thermal energy, and gold nanoparticles are established and then simplified by using the assumption of long wavelength. Analytical and numerical solutions have been evaluated for velocity, temperature, and gold nanoparticle concentration. A comparison between analytical and numerical solutions is given. The obtained results may help to understand more the process of cancer treatment with help of gold nanoparticles.
