Field: Measurement (Instruments)
Classification: CPC G  C | IPC C  G

Claim 0:
1. A paste sensor comprising:
a conductive particle having a molecularly imprinted polymer on the surface;
an oil binder for the conductive particle; and
a support,
wherein the conductive particle is a spherical graphite particle having a diameter of 3-50 μm,
wherein the conductive particle having a molecularly imprinted polymer on the surface is a conductive particle obtained by polymerizing a functional monomer, a crosslinkable monomer, and a measurement substance through contact with a graphite particle wherein an initiator was immobilized on surface of the graphite particle, and
wherein the sensor is configured to selectively respond to the measurement substance in that the molecularly imprinted polymer is structured such that when the molecularly imprinted polymer is reacted with the measurement substance, hydrophilicity of the molecularly imprinted polymer is enhanced in an amount effective such that the oil binder attached to the molecularly imprinted polymer is moved backward to increase the effective area of the molecularly imprinted polymer as an electrode, and as a result the sensor can selectively respond to the measurement substance.
