Abstract

Colloids coated with 'sticky ends' of complementary single-stranded DNA exhibit a transition upon heating from an associated to a disassociated state. This transition is investigated both experimentally and theoretically. The transition is experimentally probed by performing well controlled and characterized experiments with micrometer-sized colloids. A model is then developed, starting from the level of statistical mechanics of tethered DNA to that of colloid aggregates. This model is in excellent agreement with the experiments for the temperature and width of the transition, which are both essential properties for complex self-assembly processes.
