Abstract

Disclosed are devices and methods for moving and controlling droplets of fluids on hydrophobic surfaces through the use of magnetic fields. For example, droplets can be moved, immobilized, dispensed, coalesced, and/or divided. Also disclosed is a digital magnetofluidic device comprising a hydrophobic surface; a magnetically active fluid droplet in contact with the surface; and a magnetic field coupled with at least a portion of the droplet. Also disclosed is a digital isoelectric focusing method using the devices and methods. Also disclosed are digital microelectrochemical detection methods and digital microelectrochemical reaction methods. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.
