Biochip
First Claim
1. A biochip comprising a plurality of spots of capture material arranged on a base plate, obtained by supplying, onto said base plate by means of an ink jet system, a plurality of types of capture solutions, said capture solutions comprising said cature material dissolved in an aqueous solution, each said capture material for specifically reacting with a specimen to provide information about a structure within the specimen, wherein the plurality of spots have different spot sizes formed on said base plate, and all of said spots have uniform detection sensitivity.

Abstract
When the genetic analysis is performed by using a DNA microarray, the inspection accuracy is improved. A sample solution is supplied onto a base plate to prepare the DNA microarray comprising a large number of spots based on the sample solution arranged on the base plate. In the microarray, the planar configuration of the spot is substantially circular, and a plurality of spots having different spot sizes are formed on the base plate.
