Title:
CHEMICAL SENSOR, METHOD OF MANUFACTURING CHEMICAL SENSOR, AND METHOD OF DETECTING SPECIMEN
Document Type and Number:
Japanese Patent JP2003139775
Kind Code:
A
Abstract:
To selectively and highly sensitively detect an objective specimen.
A layer of a nano-sized particulate 10 and a layer of a dendrimer molecule 11 are formed alternatingly the layer by the layer to constitute a composite film 8 on a substrate 6. A linker unit is coupled therein to a surface of the nano-sized particulate 10 to couple the nano-sized particulate 10 to the dendrimer molecule 11 each other. A comb-shaped electrode 7 is provided on the substrate 6, and specimen vapor is detected by measuring a change of a physical characteristic of the composite film 8 when exposed to the specimen vapor.
