Ultra-sensitive biological nanosensors can be used to detect certain types of cancer in people in advance.

The system is much more sensitive than current methods and a minimum error rate in tests.

Tumors release certain proteins in the blood that are known as biomarkers. Although not all the markers are known, you are aware of many of them, so that by examining the blood flow you can know if a person suffers or not certain types of cancerous tumors.

This work, led by the Higher Council for Scientific Research (CSIC), proposes the use of biological nanosensors capable of detecting cancer biomarkers to detect tumors. One of the CSIC scientists explains that in this work two concepts have been grouped: nanomechanical and nanooptic. Both the microtrampoline and the nanoparticle have antibodies on their surface that very selectively bind to the marker, and therefore act as an explorer.

In this way, if the tumor marker is in the blood, it is registered by the presence of gold nanoparticles in this trampoline species. In addition, the nanoparticles change the color of the microtramp, and that color change is very easy to identify.

The scientist affirms that the presented technique is simple and accessible, and therefore there would be no impediment to implement in the hospital systems, although what is followed is to make clinical tests with patients and with not established biomarkers of last generation.

These and other innovations are now possible in Pharmamedic.
