The controlled manipulation of matter with radiation pressure, otherwise known as optical trapping, has emerged as a powerful experimental tool in the physical sciences. This review highlights some recent developments in the technique and application of a particular trapping technique known colloquially as ``optical tweezers.'' Even though the theory of optical tweezer operation is still evolving, their use has provided exciting new insights into fundamental processes in colloid and interface science.
