METHOD FOR MANUFACTURING MICROCHIP

摘要

[Problem] In conventional methods for manufacturing microchips, ultraviolet light was used in the adhesion of a pair of resin substrates, and that ultraviolet light gave rise to fluorescence in the surface of the resin substrate that was exposed. Therefore, if this microchip is used in fluorescent labeling where a sample is given a fluorescent marker and measurements are made, the problem is the fluorescence arising in the surface of the resin substrate having bad effects on the measurements and detection precision being reduced. [Solution] In a method for manufacturing a microchip having a pair of resin substrates in which mutually opposed surfaces are made to mutually adhere and recessed parts are formed in at least one of the mutually opposed surfaces, the mutually opposed surfaces of the pair of resin substrates are exposed to ultraviolet light, which is light of a wavelength in the ultraviolet region, before being made to adhere. Thereafter, the mutually opposed surfaces of the pair of resin substrates that have been exposed to ultraviolet light are exposed to visible light that substantially includes light with wavelengths in the visible region.
