Versatile methods are described for the fabrication of micrometer-scale particles with defined shape, ferro- or paramagnetic properties, and amphiphilic Janus surface chemistry. Examples of their utility include measuring the rheological properties of complex, two-dimensional fluid interfaces and reversible, directed self-assembly at fluid interfaces.
