Electrets
The Whitesides group (Harvard) has focused on forming electrets by several mechanisms (especially charge injection and ion exchange), and in using electrostatic fields to form patterns and position small objects. The Aksay group (Princeton) has studied colloidal (adsorbed molecules and particles on surfaces) electrets, and their use in directed self-assembly, using galvanography, electrohydrodynamic (EHD) manipulation of suspensions, surfactant aggregation, and guided growth. The Prentiss group (Harvard) has focused on electrostatic interactions between ssDNA and dsDNA, and monovalent and divalent ions; this interaction does NOT depend strictly on ionic concentration: divalent ions have a much larger impact. The effect may also depend on the length of the DNA. The Suo group (Harvard) has studied theoretically the assembly of microspheres on a patterned electrode under the influence of an applied voltage.
