This sensor can diagnose cancer, Parkinson’s and Alzheimer’s disease


Thanks to the work that has been developing in the National Nanotechnology laboratory of Campinas, located in the well known Brazilian city of Sao Paulo, we learned of the existence new dean electronic sensor that can detect the existence of different molecules associated to some types of cancer and neurodegenerative diseases such as Parkinson or Alzheimer’s.

Entering a little more in detail, the truth I was surprised the little information that exists on the matter taking into account the great value that can have this work, we have a small organic transistor scale Nano. This biosensor has been mounted directly on a glass slide and contains in its interior a very reduced Glutathione (GSH) form, a tripeptide composed of three amino acids, glutamate, glycine, cystine.

As I have been able to understand, GSH has a property that is essential for the proper functioning of this sensor and it is that it reacts one manee very specific when it comes in contact with the enzyme glutathione S-transferase (GST), which is associated with diseases such as cancer breast, Parkinson’s or Alzheimer’s among others. To come into contact with this enzyme transistor detects reaction and sends a signal that can serve to physicians, due to its precision, to offer a diagnosis.

According to statements by Carlos César both jester, head of the National Nanotechnology laboratory functional devices:

Thanks to its Nano sensitivity, the device can detect this type of molecules even when they are present in very low levels in the material examined.

For the moment is little more known about this development except that it depends on a bigger project where you try to design a diagnostic device fast so they can quickly process liquids that determine and detect if a patient suffers from one of these diseases.
