A novel electrically conductive polymer, a sensor using the electrically conductive polymer, and a method for detecting a target molecule that hybridizes to a probe, using the sensor, are provided. The electrically conductive polymer has the following formula: where m is 1, 2, or 3; R is a hydroxysuccinimidyl group, a hydroxyphthalimidyl group, or a pentafluorophenolyl group; and n is zero or an integer.

Electrically conductive polymer, sensor using the same, and method for detecting target molecule using the sensor

A conductive compound of formula (I) below, an electrode coated with the conductive compound, a sensor including the electrode, and a target molecule detection method using the sensor are provided: wherein Y is a carbonyl or &#x2014;NH&#x2014;; R is one of H, OH, a leaving group, and a probe group; l is an integer from 3 to 6; m is an integer from 1 to 4; and n is an integer from 0 to 3.

Conductive compound, electrode and sensor containing the same, and target molecule detection method using the sensor

A novel electrically conductive polymer, a sensor using the electrically conductive polymer, and a method for detecting a target molecule that hybridizes to a probe, using the sensor, are provided. The electrically conductive polymer has the following formula:where m is 1, 2, or 3; R is a hydroxysuccinimidyl group, a hydroxyphthalimidyl group, or a pentafluorophenolyl group; and n is zero or an integer.

An ink composition for ink-jet printers is provided which includes a chromophore, a solvent, a co-solvent, a humectant, a surfactant, a viscosity adjuster and an additive. The additive is a nitrogen-containing heterocyclic compound. This nitrogen-containing heterocyclic compound has the hydroxy groups which improve miscibility with water, thereby preventing clogging of nozzles during use. The present invention increases the affinity for dye used as a chromophore and for the hydroxy groups of paper after discharging of ink, which allows the chromophore to easily fix on the paper, thus enhancing smearfastness of the ink composition after printing.
