Studies of such<br /> DNA-coated colloids promise to offer insights into the necessary<br /> ingredients for gaining exquisite control over colloidal<br /> self-assembly. However, experimental exploration on self assembling<br /> ordered structures is still in its infancy, with the main hurdle being<br /> the lack of understanding of the thermodynamics and kinetics of<br /> DNA-mediated self-assembly. Detailed exploration of these structures<br /> via computer simulations on the other hand is hindered by the lack of<br /> adequate techniques and efficient coarse-grained models. In this<br /> presentation, we develop models of DNA-coated colloids at different<br /> levels of coarse-graining and at the experimentally relevant<br /> conditions. The different models are assessed for their validity and<br /> new simulation techniques developed to draw the phase diagram of such<br /> colloids. Finally, our findings (as e.g. melting temperature of the<br /> crystals or equilibrium lattice spacing) are compared to experimental<br /> results, showing agreement to within few percent and proving the<br /> strength of our coarse-grained models.</div> Wed, 12 Oct 2011 13:32:44 GMT Feenstra https://wiki.cs.vu.nl/ibivu/Talk:2011-10-20_Bianca_Mladek
