There is great interest today in what is known as predictive medicine,i.e that branch of medicine which investigates on fragilities or defects of healthy individuals likely to develop certain illnesses. Much work is carried out on the development of biosensors which are are increasingly able to detect nucleic acids, i.e. Dna, to carry out accurate tests, even at home, reducing at the same time costs and making for example preventive screening on a large scale possible.
Other systems instead aim at integrating all the phases of medical treatment: analysis, diagnosis, treatment and treatment effectiveness. Technologies which exploit not only micro-elettronics and nano systems, but also information technology and commonly used devices (smartphones, tablets, pc) in order to monitor patients and medical treatment constantly, even 24 hrs a day.
