Two-Photon Excitation of Azobenzene Photoswitches for Synthetic Optogenetics
Applied Sciences, 2020 Synthetic optogenetics is an emerging optical technique that enables users to photocontrol molecules, proteins, and cells in vitro and in vivo. This is achieved by use of synthetic chromophores—denoted photoswitches—that undergo light ...

Maskless Writing of Surface-Attached Micro-Magnets by Two-Photon Crosslinking
Actuators, 2023 Surface-bound 3D micro-magnets are fabricated from photoreactive copolymers filled with magnetic nanoparticles by maskless 3D writing. The structures are generated by 2-photon crosslinking (2PC), which allows direct writing into solid films of composites

Ca2+ signaling in arterioles and small arteries of conscious, restrained optical biosensor mice
Frontiers in Physiology, 2014 Two-photon fluorescence microscopy and conscious, restrained optical biosensor mice were used to study smooth muscle Ca2+ signaling in ear arterioles. Conscious mice were used in order to preserve normal mean arterial blood pressure (MAP) and sympathetic

A laser–plasma platform for photon–photon physics: the two photon Breit–Wheeler process
New Journal of Physics, 2021 We describe a laser–plasma platform for photon–photon collision experiments to measure fundamental quantum electrodynamic processes. As an example we describe using this platform to attempt to observe the linear Breit–Wheeler process.

Molecular design strategy to alleviate environmental interference on two-photon fluorescence probes
Cell Reports Physical Science, 2021 Summary: Electron donor-acceptor (D-A)-type molecules are the most widely employed two-photon scaffolds. Unfortunately, current D-A-type fluorophores suffer from serious solvent-dependent emission wavelength and brightness, thwarting their use for high ...
