The present invention relates to a structure and manufacturing process of
a nano device transistor for a biosensor. The structure, the
manufacturing process and the related circuit for a carbon nano tube or
nano wire transistor biosensor device are provided. The refurbished nano
device is used for absorbing various anti-bodies so as to detect the
specific antigens or absorbing various biotins. Therefore, the object of
the present invention to detect the specific species for bio measurement
can be achieved.
