Quantum light for biomedical imaging

Broadband energy entangled photons are a promising source of quantum light to shed further insight into the structure and dynamics of cellular processes. EU-funded scientists used this source in a fluorescence imaging technique.

Being one of the most powerful tools in biological imaging, two-photon excitation microscopy enables 3D structural and functional imaging of biosamples. This imaging technique employs the two-photon absorption (TPA) process in which uncorrelated photons interact with the living cells. Because of small interaction strengths, TPA requires large light intensities that may damage sensitive cells and tissues.
