ABSTRACT

The “Human Genome Project”, which has recently gained signifi cant achievements, has witnessed the general interests in genomic research programs. The importance in genomic applications have been increased by the high potential benefi ts that the DNA biosensors are expected to bring to clinical, civil defense and societal settings. The latter range from pharmacogenomic applications, to the diagnosis of disease and forensic purposes. In the fi eld of medical diagnosis, increasing innovations and novel confi gurations have been developed in order to detect diseases such as cancer in its early stages. Early cancer detection helps in avoiding loss of life and also the high cost of treatments for these kinds of diseases, becoming indirectly in one solution of greater problems public health issues at medium and long term: the cost overruns (Yang et al. 1999).
