abstract = {Locomotion and transport of microorganisms in fluids is an
essential aspect of life. Search for food, orientation
toward light, spreading of off-spring, and the formation of
colonies are only possible due to locomotion. Swimming at
the microscale occurs at low Reynolds numbers, where fluid
friction and viscosity dominates over inertia. Here,
evolution achieved propulsion mechanisms, which overcome and
even exploit drag. Prominent propulsion mechanisms are
rotating helical flagella, exploited by many bacteria, and
snake-like or whip-like motion of eukaryotic flagella,
utilized by sperm and algae. For artificial microswimmers,
alternative concepts to convert chemical energy or heat into
directed motion can be employed, which are potentially more
efficient. The dynamics of microswimmers comprises many
facets, which are all required to achieve locomotion. In
this article, we review the physics of locomotion of
biological and synthetic microswimmers, and the collective
behavior of their assemblies. Starting from individual
microswimmers, we describe the various propulsion mechanism
of biological and synthetic systems and address the
hydrodynamic aspects of swimming. This comprises
synchronization and the concerted beating of flagella and
cilia. In addition, the swimming behavior next to surfaces
is examined. Finally, collective and cooperate phenomena of
various types of isotropic and anisotropic swimmers with and
without hydrodynamic interactions are discussed.},
