abstract = {We characterize via small-angle neutron scattering the
structural properties of a mixture of all-DNA particles with
functionalities 4 (A) and 2 (B) constrained by design to
reside close to the percolation threshold. DNA base
sequences are selected such that A particles can only bind
with B ones and that at the studied temperature (10 °C) all
AB bonds are formed and long-lived, originating highly
polydisperse persistent equilibrium clusters. The
concentration dependence of the scattered intensity and its
wavevector dependence is exploited to determine the fractal
dimension and the size distribution of the clusters, which
are found to be consistent with the critical exponents of
the 3-D percolation universality class. The value of DNA
nanoparticles as nanometric patchy colloids with
well-defined functionality, bonding selectivity, and
exquisite control of the interaction strength is
demonstrated.},
