Janus particles are colloidal particles whose surface has been modified differently in different locations, creating so-called patches. In solution, they often self-assemble into ordered structures. We have developed a detailed model for them, which includes surface chemistry and explicit solvent molecules. In the project, we plan to study the formation of three-dimensional structures and, in particular, active colloids, i.e., Janus particles that have some means of propulsion, usually by carrying one catalytic patch on their surface. We will compare the ordering behaviour of active and passive Janus particles and also study active particles near walls.
