Colloids are particles of about a millionth of a meter that,when dispersed in a solvent, may assemble into sophisticatedstructures and form materials whose properties can be exploited:gels, microcapsules for drug delivery, catalytic media.Most studies so far seek that particles spontaneously “self-assemble” into these structures at constant conditions.This is the most straightforward and desirable route. However,a structure with desired properties is not alwaysaccessible via self-assembly. This research program plansto investigate how the assembly of colloidal structurescan be assisted by dynamically manipulating the conditionsin which the assembly process takes place. The proposed research plansto investigatecolloidal structures of technological or scientific relevance such as gels, vesicles and crystals, expecting to make importantadvancements towards the formation of these structures and the control of their properties.This will be done by means of computer simulations, vital to the design of new assembledcolloidal structures because they enable the exploration of a largeparameter space before starting painstaking experiments.
