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.

Surfactants are provided that have a hydrophobic tail portion and a hydrophilic head portion. The hydrophilic head portion includes a terminal dialkyl-substituted tertiary amine or a terminal cycloalkyl-substituted tertiary amine. Also provided are pigment-based inks employing the surfactant, a combination of an electronic display and the pigment-based inks, and a process for reducing conductivity in primary amine-based surfactants and improving reliability of electronic inks employing such surfactants.

A dual color electronically addressable ink includes a non-polar carrier fluid; a first colorant of a first color; and a second colorant of a second color that is different than the first color. The first colorant includes a first particle core, and a first functional group attached to a surface of the particle core. The first functional group is capable of carrying a positive charge and is chosen from a base or a salt of the base. The second colorant includes a particle core, and a second functional group attached to a surface of the particle core. The second functional group is capable of carrying a negative charge and is chosen from an acid or a salt of the acid. The ink further includes an additive chosen from polyhydroxystearic amide salt, polyhydroxystearic acid, aromatic butyric acid, and combinations thereof.

An electronic ink containing charged particles includes a combination of resin particles, a pigment, and a charge director. The resin particles exhibit an average particle size less than 1.0 micron and contain a resin that exhibits a molecular weight of 500 to 20,000. The pigment is loaded on the resin particles. The charge director can physically associate with the resin particles. The charged particles may be negative or positive.
摘要:
A method for making a cross-linked polymer network is disclosed herein. A mixture is formed of i) an electro-optic chromophore, ii) any of a cross-linkable monomer or a cross-linkable oligomer, and iii) an initiator in a solvent. Poling of the electro-optic chromophore is initiated by exposing the mixture to an electric field. While the mixture is being exposed to the electric field, the mixture is subjected to ultraviolet light or heat to initiate cross-linking of the any of the cross-linkable monomer or the cross-linkable oligomer to form a matrix of the cross-linked polymer network.
