Query: Binding branched and linear DNA structures: from isolated clusters to
  fully bonded gels   The proper design of DNA sequences allows for the formation of well defined
supramolecular units with controlled interactions via a consecution of
self-assembling processes. Here, we benefit from the controlled DNA
self-assembly to experimentally realize particles with well defined valence,
namely tetravalent nanostars (A) and bivalent chains (B). We specifically focus
on the case in which A particles can only bind to B particles, via
appropriately designed sticky-end sequences. Hence AA and BB bonds are not
allowed. Such a binary mixture system reproduces with DNA-based particles the
physics of poly-functional condensation, with an exquisite control over the
bonding process, tuned by the ratio, r, between B and A units and by the
temperature, T. We report dynamic light scattering experiments in a window of
Ts ranging from 10{\deg}C to 55{\deg}C and an interval of r around the
percolation transition to quantify the decay of the density correlation for the
different cases. At low T, when all possible bonds are formed, the system
behaves as a fully bonded network, as a percolating gel and as a cluster fluid
depending on the selected r.
