Emerging bio-microfluidic systems are embracing electroosmosis mechanisms to supervise ionized physiological fluids. Impelled by the exploration of electro-micro-pumping mechanisms in bio-engineering domains, in the present inquisition, a research policy associated with hemodynamical deportment of blood circulation under suspension of gold and alumina nanoparticles in a diverging fatty artery subject to electro-osmotic driving forces is conducted. The exact solutions of the resulting model equations associated with the proposed wall conditions are acquired in terms of Bessel functions under larger wavelength and a smaller ratio of inertial and viscous force. Numerical integration is computed through the NDSolve technique. Plotting and elaboration are performed to explore the physical insight into hemodynamics under diverse parametric aspects. Crucial findings of the study include that a raised electro-osmotic parameter elevates the intensity of blood streaming in the core zone of the artery and it established a declining pattern in the close vicinity of the arterial wall. The parameters linked with electroosmosis contribute to thermal emaciation of blood streaming in the artery. The heat transmission rate across the arterial wall sharply declines for ascending values of the electro-osmotic parameter and Helmholtz-Smoluchowski velocity. The structure of blood boluses is also outlined under the impact of involved parameters in brief. Pure blood offers less size and number of blood boluses near the arterial wall compared to hybrid nano-blood. From a bio-engineering point of view, the modelling study can contribute significantly to biomechanical and medical processes and therapeutic implications.
