  • Patent number: 9013781
    Abstract: Pigment-based inks are provided. The inks include a non-polar carrier fluid and pigment particles suspended in the non-polar carrier fluid. The pigment particles have tri-block copolymer grafts. Each tri-block copolymer graft comprises a tri-block copolymer having three portions: an inner block attached to the pigment particle, a middle block, and an outer block, wherein the inner and outer blocks each contain bulky organic groups to help facilitate solubility of the functionalized polymers in the non-polar solvent and to provide steric stabilization of the resulting particle dispersion in the non-polar solvent, and wherein the middle block contains either acidic or basic functionalized side groups that facilitate charging of the pigment particle. A combination of an electronic display and an electronic ink employing the pigment and a process for making the pigment-based inks are also provided.

  • Publication number: 20150103340
    Abstract: A scattering spectroscopy nanosensor includes a nanoscale-patterned sensing substrate to produce an optical scattering response signal indicative of a presence of an analyte when interrogated by an optical stimulus. The scattering spectroscopy nanosensor further includes a protective covering to cover and protect the nanoscale-patterned sensing substrate. The protective covering is to be selectably removed by exposure to an optical beam incident on the protective covering. The protective covering is to prevent the analyte from interacting with the nanoscale-patterned sensing substrate prior to being removed.
