Filamentous bacteriophages such as fd-like viruses are monodisperse rod-like
colloids that have well defined properties: diameter, length, rigidity, charge
and chirality. Engineering those viruses leads to a library of colloidal rods
which can be used as building blocks for reconfigurable and hierarchical
self-assembly. Their condensation in aqueous solution \th{with additive
polymers which act as depletants to induce} attraction between the rods leads
to a myriad of fluid-like micronic structures ranging from isotropic/nematic
droplets, colloid membranes, achiral membrane seeds, twisted ribbons,
π-wall, pores, colloidal skyrmions, M\"obius anchors, scallop membranes to
membrane rafts. Those structures and the way they shape shift not only shed
light on the role of entropy, chiral frustration and topology in soft matter
but it also mimics many structures encountered in different fields of science.
On one hand, filamentous phages being an experimental realization of colloidal
hard rods, their condensation mediated by depletion interactions constitutes a
blueprint for self-assembly of rod-like particles and provides fundamental
foundation for bio- or material oriented applications. On the other hand, the
chiral properties of the viruses restrict the generalities of some results but
vastly broaden the self-assembly possibilities
