(SciTechDaily) Researchers from the Università degli Studi Roma Tre in Italy showed that quantum light can be used to track enzyme reactions in real time. The work brings together quantum physics and biology in an important step toward the development of quantum sensors for biomedical applications.
The complex molecules known as enzymes are responsible for many processes inside our bodies. However, they can be difficult to study with optical approaches because too much light will reduce their activity or even stop it altogether.
The multidisciplinary group of researchers showed that light controlled at the single-photon, or quantum, level can allow accurate measurements without disrupting enzymatic activity.
