  This brief review discusses electronic properties of mesoscopic
graphene-based structures. These allow controlling the confinement and
transport of charge and spin; thus, they are of interest not only for
fundamental research, but also for applications. The graphene-related topics
covered here are: edges, nanoribbons, quantum dots, $pn$-junctions,
$pnp$-structures, and quantum barriers and waveguides. This review is partly
intended as a short introduction to graphene mesoscopics.
