Microanalysis Method and System Using Field Effect Transistor

摘要

PURPOSE: A microanalysis method and system using a filed effect transistor is provided to detect a small amount of materials through a simple process. CONSTITUTION: A microanalysis method comprises: a step of preparing a field effect transistor(FET) having a receptor molecule-fixed channel region; a step of supplying a test sample and nanoparticular conjugate to the FET to form the nanoparticular conjugate on the channel region; a step of growing a probe material on the channel region; and a step of measuring current in the channel region.
