(Photonics.com) A research team at Università degli Studi Roma Tre has shown that quantum light can be used to track enzyme reactions in real time. The researchers developed a setup that allowed them to control the light at the level of a single photon. This made it possible to use low illumination without disrupting the enzymes, with the potential to achieve improved sensitivity.
“This work is just one example of what quantum sensors could do,” research team leader Ilaria Gianani said. “Quantum sensors could be used to optimally use light for countless applications, including biological imaging, magnetic field sensing, and even detection of gravitational waves.”
