    Abstract: A device for optical mapping of protein binding sites, in particular, transcription factor binding sites, on single DNA molecules, includes an insulating substrate having two parallel channels and at least one slit connecting the two channels, a coverslip on the substrate, at least two reservoirs on the substrate connecting the channels of the insulating substrate, and at least two electrodes in the reservoirs. When the reservoirs are filled with a buffer solution, the electrodes are in electrical contact in the buffer solution.

    Abstract: Methods, structures, devices and systems are disclosed for rapid enrichment and mass transport of biomolecules (e.g., such as proteins) or other small molecules and particles using electrodeless dielectrophoresis (eDEP). In one aspect, a device to aggregate molecules includes a substrate that is electrically insulating, an electrically insulative material formed on the substrate and structured to form a channel to carry an electrically conducting fluid containing particles, a constriction structure formed of the electrically insulative material and located in the channel to narrow a channel dimension and forming an opening with a size in the nanometer range, and a circuit coupled to the substrate to apply an ac electric field and a dc bias electric field along the channel, in which the constriction structure is structured to magnify the applied ac electric field to produce forces that operate collectively to aggregate the particles.

    Abstract: Methods, systems, and devices are disclosed for molecular capture, manipulation, and analysis. In one aspect, a device to aggregate and characterize particles in a fluid includes an electrically insulative substrate including a channel to carry an electrically conducting fluid containing particles, electrodes located in the channel forming a nanoscale opening and including an insulating layer over their surface at the opening, a first circuit to apply a non-uniform ac electric field and a dc bias signal across the electrodes, in which the applied non-uniform ac electric field produces a positive dielectrophoretic force to aggregate the particles in a trapping region including the opening and adjacent region, a second circuit to detect changes in a dc current caused by at least some of the particles in the trapping region, and an optical device that directs a coherent light beam on the opening to determine Raman spectra of the particles in the trapping region.
