Currently the most precise method for 3D printing complex microscopic features is two-photon lithography. The technique uses ...

Two-photon microscopy is a type of fluorescence microscopy that, rather than exciting the sample with a single photon, makes use of multiple photons. The advantage over more traditional one-photon ...

Two-photon excitation (TPE) microscopy enables imaging of living tissues up to a depth of one millimeter, which is 6 to 10-fold deeper than with confocal microscopy. Like confocal microscopy, TPE ...

Lawrence Livermore National Laboratory (LLNL) engineers and scientists, in collaboration with Stanford University, have ...

Recent studies of brain functions and neural activity have benefited from advances in two-photon microscopy, and the increased resolutions and functional imaging that the technique allows. However, ...
