New molecule enables quick drug monitoring

Monitoring the drug concentration in patients is critical for effective treatment, especially in cases of cancer, heart disease, epilepsy and immunosuppression after organ transplants. However, current methods are expensive, time-consuming, and require dedicated personnel and infrastructure away from the patient. Publishing in Nature Chemical Biology, scientists at EPFL introduce novel light-emitting sensor proteins that can quickly and simply show how much drug is in a patient's bloodstream by changing the color of their light. The method is so simple that it could be used by patients themselves.
