This theme has also promising new applications in the context of nanotechnology, biophysics and medicine ranging from cancer treatment and targeted drug delivery to medical imaging. The aim of this work is to study the behavior of nanorods suspended at dilute concentration in a liquid flowing in a 3-dimensional simple shear flow, near a flat solid surface. The dynamics of these nanorods are effectively determined by three independent forces, the first is the hydrodynamic force stemming from the shear flow of the liquid, the second is of thermal origin that causes Brownian diffusion, and the third is due Van der Waals forces arising from dipole - dipole interaction. Additionally, a repulsive interaction springs up, due to Pauli principle, when the nanorods are just about to touch the surface. Simulation techniques ranging from Taylor expansion and random walks to Monte Carlo simulation were employed to extract the probability distribution function of the nanorods as a function of their orientation and elevation. \bibliographystyle{plain} \begin{thebibliography}{10} \bibitem{Atwi-Hijazi-Khater-1} {\sc A.
