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 ...

A never-before-seen image of individual oxygen atoms dissolved in water has been captured.

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

Femtosecond Projection Two-photon Lithography (FP-TPL) printing technology increases the printing speed by 1,000 – 10,000 times, and reduces the cost by 98%. It controls the laser spectrum via ...

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, ...

We’ve said it before, but we cast a wary eye at any superlative claims that come our way. “World’s fastest” or “world’s first” claims always seem to be quickly debunked, but when the claim of “World’s ...
