Abstract:
1. A method of controllably localizing particles at specific locations on a substrate, each specific location proximal to an individually addressable force transducing element, the method comprising: providing a plurality of particles proximal to the substrate; providing a substantially uniform magnetic field that encompasses the specific locations and the particles; selecting one or more force transducing elements to be activated; and controllably localizing one or more particles to the specific locations by activating the selected force transducing elements to transduce a motive force to one or more particles proximal to the corresponding specific location, wherein the magnitude of the transduced force is substantially altered by the presence of the uniform field; and detecting, at one or more of the activated locations, the number of particles attracted to the location.
