DNA sensing is an emerging technology based on hybridisation reaction between an immobilised DNA probe and a molecular target, consisting of a probe complementary sequence in solution. Many application have been developed in the field of environmental, food and clinical analysis. Surface plasmon resonance and piezoelectric sensing are reported as transduction principles for DNA-based devices. These techniques are able to monitor in real-time and without the use of any label the hybridisation reaction between nucleic acids. Particular attention is given to Genetically Modified Organism detection.
