detected, ranging from 9% to 35% for different vapors. An array of such graphene
FETs is a fine electronic nose. A simple and effective protein detection using
thermally reduced graphene oxide sheet decorated with gold antibody conjugates
was also reported ( Mao et al. 2010 ).

2.2 DNA Detection and Sequencing Using Nanopores

This section is dedicated to DNA sequencing, i.e., to detecting the sequence of
bases A, G, C, T, using techniques based on nanotechnologies. DNA sequencing
is of paramount importance for the decoding of the human genome, and based
