<P>PROBLEM TO BE SOLVED: To provide a field effect transistor having a gold layer, to provide a microfluidic device having the field effect transistor, and to provide a method for detecting an analyte containing a thiol group by utilizing the field effect transistor and the microfluidic device. <P>SOLUTION: The field effect transistor comprises a substrate made of a semiconductor material, a source region and a drain region that are formed separately each other in the substrate and are doped to a conductivity type that differs from that of the substrate, a channel region arranged between the source and drain regions, an insulating layer that is arranged on a channel region and is composed of an electrically insulating material, and a gate electrode separately arranged on the insulating layer. In the field effect transistor, a field effect transistor for detecting an analyte having a thiol group, further having a gold layer positioned on an insulating layer, the microfluidic device having the field effect transistor, and the method for detecting the analyte containing the thiol group by utilizing the field effect transistor and the microfluidic device are composed. <P>COPYRIGHT: (C)2008,JPO&INPIT |
