Abstract
The invention relates to microfluidic devices and methods that employ electromagnetic radiation to move a droplet of fluid on a fluid-transporting surface of a substrate. Typically, radiation of a particular wavelength is directed through a substantially transparent material, and the radiation imparts an optical trapping force to move the droplet. In addition, a means for reducing evaporative loss from the droplet may be provided.
