Two-photon excitation (TPE) has emerged as a transformative approach in photodynamic therapy (PDT), harnessing near-infrared light to activate photosensitisers deep within tissue while minimising ...

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 ...

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

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 microscopy (TPM) has revolutionized the field of biology by enabling researchers to observe complex biological processes in living tissues at high resolution. In contrast to traditional ...

The new approach uses a purely optical technique called stimulated two-photon excitation to generate streams of photons in different polarization states directly from a quantum dot without requiring ...

Researchers at Peking University have developed DUET, a breakthrough dual-color miniature two-photon microscope that overcomes two persistent barriers ...

The Ultima 2Pplus All-Optical Multiphoton System combines high resolution, deep imaging capability, speed, and operational flexibility, enabling researchers to efficiently perform simultaneous imaging ...
