Title:
BILIRUBIN SENSOR UTILIZING MUTUAL ADSORPTION FILM
Document Type and Number:
Japanese Patent JP3868379
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a technology capable of detecting bilirubin simply.
SOLUTION: A bilirubin detection membrane to be used is constituted of a mutual adsorption film wherein an aromatic amine having two or more amino groups and a spiral polymer having an ester group on the side chain are laminated as a plurality of layers alternately through a covalent bond between the amino group and the ester group on a substrate. After the membrane is subjected to a diazotization reaction and then immersed in a biosample, an ultraviolet visible absorption spectrum or a frequency change by a quartz oscillator is measured to thereby detect the bilirubin.
