Abstract
Abstract DNA-coated colloids (DNACCs) are one of the most exciting systems for the programmable self-assembly of colloidal structures. Their versatility arises naturally from the selectivity and sensitivity of DNA hybridization, which allows to finely tune the interparticle attraction to an unprecedented level. Such a possibility opens the door to assembling highly complex and stimuli-responsive structures, beyond what is achievable with other colloidal interaction. However, the link between the grafted DNA sequences and the final properties of this structures is not trivial. In particular, the physics of multivalent binding embeds DNACCs with peculiar properties which must be carefully understood to exploit the full potential of this system. To this purpose, we will describe here various theoretical and computational models developed to study DNACCs, focusing on how their main findings can be used to guide colloidal engineering.
