Query: Adaptable DNA interactions regulate surface triggered self assembly   DNA-mediated multivalent interactions between colloidal particles have been
extensively applied for their ability to program bulk phase behaviour and
dynamic processes. Exploiting the competition between different types of
DNA-DNA bonds, here we experimentally demonstrate the selective triggering of
colloidal self-assembly in the presence of a functionalised surface, which
induces changes in particle-particle interactions. Besides its relevance to the
manufacturing of layered materials with controlled thickness, the intrinsic
signal-amplification features of the proposed interaction scheme make it
valuable for biosensing applications.
