      abstract     = {Double-stranded DNA (dsDNA) fragments exhibit noncovalent
                      attractive interactions between their tips. It is still
                      unclear how DNA liquid crystal self-assembly is affected by
                      such blunt-end attractions. It is demonstrated that stiff
                      dsDNA fragments with moderate aspect ratio can specifically
                      self-assemble in concentrated aqueous solutions into
                      different types of smectic mesophases on the basis of
                      selectively screening of blunt-end DNA stacking
                      interactions. To this end, this type of attractions are
                      engineered at the molecular level by constructing DNA
                      duplexes where the attractions between one or both ends are
                      screened by short hairpin caps. All-DNA bilayer and
                      monolayer smectic-A type of phases, as well as a columnar
                      phase, can be stabilized by controlling attractions
                      strength. The results imply that the so far elusive
                      smectic-A in DNA rod-like liquid crystals is a
                      thermodynamically stable phase. The existence of the bilayer
                      smectic phase is confirmed by Monte-Carlo simulations of
                      hard cylinders decorated with one attractive terminal site.
                      This work demonstrates that DNA blunt-ends behave as
                      well-defined monovalent attractive patches whose strength
                      and position can be potentially precisely tuned,
                      highlighting unique opportunities concerning the
                      stabilization of nonconventional DNA-based lyotropic liquid
                      crystal phases assembled by all-DNA patchy particles with
                      arbitrary geometry and composition.},
