abstract = {Drug delivery by micro- and nano-carriers enables
controlled transport of pharmaceuticals to targeted sites.
Even though carrier fabrication has made much progress
recently, the delivery including controlled particle
distribution and adhesion within the body remains a great
challenge. The adhesion of carriers is strongly affected by
their margination properties (migration toward walls) in the
microvasculature. To investigate margination characteristics
of carriers of different shapes and sizes and to elucidate
the relevant physical mechanisms, we employ mesoscopic
hydrodynamic simulations of blood flow. Particle margination
is studied for a wide range of hematocrit values, vessel
sizes, and flow rates, using two- and three-dimensional
models. The simulations show that the margination properties
of particles improve with increasing carrier size. Spherical
particles yield slightly better margination than ellipsoidal
carriers; however, ellipsoidal particles exhibit a slower
rotational dynamics near a wall favoring their adhesion. In
conclusion, micron-sized ellipsoidal particles are favorable
for drug delivery in comparison with sub-micron spherical
particles},
