Description
Creating the next generation of dynamic colloidal materials that change their structure based on external stimuli may require the capability to precisely manipulate colloidal particles. Colloidal particles can be manipulated using a variety of forces, such as electric, magnetic, and optical, but so far chemical reactions have been neglected. We consider here a novel paradigm for using chemical gradients to precisely manipulate colloidal particles in a microfluidic device. Specifically, we show in simulation that model predictive control can be applied to a set of spatially localized chemical reactions to move a small number of colloidal particles on a circular trajectory.
