Nanobiosensor To Detect Tumors

The detection of cancer through blood or saliva samples would facilitate early detection and make it less traumatic for the patient.

This is the goal of a group of Argentine researchers who are developing a nanobiosensor from carbon nanotubes.

This nanobiosensor consists of two microelectrodes connected by a bridge of nanotubes with antibodies. Since electrical signals produced by the union of a tumour with the sensor molecule biosensor it detects the appearance of a tumour.

The development is part of the project Nodo Nanotec, funded by the Comisión Nacional de Energía Atómica and the Agencia de Promoción Científica y Tecnológica. The Universidad Nacional de Bahía Blanca and the Instituto de Investigaciones Científicas y Técnicas para la Defensa are also collaborating.
