Consider a non$-$spherical particle with an aspect ratio of $2($length$/$diameter$)$ suspended in blood at a temperature of $37$C$.$ The particle has a major axis length of $2\backslash$mu m and a minor axis diameter of $1\backslash$mu m$.$ The blood viscosity $(\backslash$eta $)$ at this temperature is $4\backslash$times $103$Pa$$s$.$ Assume the particle behaves as a prolate spheroid. Calculate the diffusion coefficient $($D$)$ for this particle using an appropriate modification of the Stokes$-$Einstein equation.
