Assistant Professor of Biomedical Engineering Yi Xue works on 2P-FOCUS, a new two-photon microscopy system, in her lab. The system promises novel insights into biological features that were once only ...

Two-photon absorption and quantum light spectroscopy have emerged as transformative tools in modern optical research. At the heart of these techniques is the simultaneous absorption of two photons to ...

Two-photon polymerization (TPP) and direct laser writing (DLW) techniques utilise focused ultrashort laser pulses to induce highly localised photochemical reactions in photosensitive materials, ...

Researchers have developed a new two-photon fluorescence microscope that captures high-speed images of neural activity at cellular resolution. By imaging much faster and with less harm to brain tissue ...

New approach offers great potential for ophthalmic diagnostics and AR/VR applications. “Two-photon vision offers great potential for ophthalmic diagnostics”. Scientists at ICTER, the International ...

Photon upconversion through high harmonic generation, multiphoton absorption, Auger recombination and phonon scattering performs a vital role in energy conversion and renormalization. Excitons, the ...

Intravital brain imaging is a valuable tool for studying neurons, glial cells, and their surroundings in living animals. It allows the investigation of neurological illnesses, therapeutic efficacy, ...
