Generalized phase contrast and temporal focusing are combined to shape two-photon excitation patterns that elicit large photocurrents in ChR2-expressing neurons in culture and slices. This method ...

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 research group led by Takashi Saito, of the Ehime University Graduate School of Medicine, developed a 2-photon excitation light-sheet fluorescence microscope which (1) lowers phototoxicity, (2 ...

The two-photon microscopy technique reduced photodamage, meaning the embryos were viable after imaging and produced healthy full term organisms once implanted. The conventional imaging techniques ...

An example is the 2023 project at France's École Polytechnique studying how two-photon microscopy can reduce photodamage while also allowing deeper imaging with longer wavelength excitation. This ...

November 11, 2008 (Orlando, Florida) — Intense pulsed light (IPL), alone and with blue light, appears to be much better than pulsed dye laser (PDL) in treating patients with photodamage ...

A team of researchers from ICFO, Politecnico di Milano, Micro Photon Devices, ... New quantum microscope enhances sensitivity avoiding photodamage. ICFO-The Institute of Photonic Sciences. Journal ...

Types of Nonmalignant Photodamage.Damage to epidermal structures results in several nonmalignant skin conditions. Solar lentigos (liver spots) in sun-exposed areas may grow in size, change colour ...
