IIT Roorkee scientists develop dopamine sensor to detect neurological diseases at an early stage- Education News
A team of scientists at IIT Roorkee has developed a dopamine sensor to detect neurological diseases such as schizophrenia and Parkinson’s at an early stage.
When a person suffers from these diseases, the level of a chemical called dopamine is altered in the brain, and the sensor works by measuring the dopamine levels. It can detect even a small change in the level of this chemical in our brain thus detecting the possibility of neurological disorders like schizophrenia and Parkinson’s disease. As most of these diseases cannot be completely cured, early detection helps in controlling the advancement of the disease. In this regard, the sensor developed at IIT Roorkee has the potential to play a significant role in the medical field.
The IIT Roorkee team has used a material called graphene quantum dot which was mixed with sulfur and boron for fabricating these sensors. In the presence of a very small amount of dopamine, this sensor changes light intensity which can be easily measured, thus providing an estimate of the amount of dopamine in the brain.
