Journal articleRowlands CJ, Park D, Bruns OT, et al., 2017, , Light: Science and Applications, Vol: 6, Pages: 1-9, ISSN: 2047-7538
Three-photon wide-field depth-resolved excitation is used to overcome some of the limitations in conventional point-scanning two- and three-photon microscopy. Excitation of chromophores as diverse as channelrhodopsins and quantum dots is shown, and a penetration depth of more than 700 μm into fixed scattering brain tissue is achieved, approximately twice as deep as that achieved using two-photon wide-field excitation. Compatibility with live animal experiments is confirmed by imaging the cerebral vasculature of an anesthetized mouse; a complete focal stack was obtained without any evidence of photodamage. As an additional validation of the utility of wide-field three-photon excitation, functional excitation is demonstrated by performing three-photon optogenetic stimulation of cultured mouse hippocampal neurons expressing a channelrhodopsin; action potentials could reliably be excited without causing photodamage.

Conference paperRowlands CJ, Bruns OT, Franke D, et al., 2016,
The tissue penetration depth of temporal focusing is increased by utilizing longer excitation wavelengths combined with quantum dots possessing extremely high two-photon crosssections. Cerebral vasculature is imaged in a mouse brain in vivo.

Journal articleRowlands CJ, Wu J, Uzel SGM, et al., 2014, , Laser Physics Letters, Vol: 11, ISSN: 1612-2011
A method for selectively inducing apoptosis in tumor nodules is presented, with close-to-cellular level resolution, using 3D-resolved widefield temporal focusing illumination. Treatment times on the order of seconds were achieved using Verteporfin as the photosensitizer, with doses of 30 μg ml−1 and below. Results were achieved on both 2D and 3D cell cultures, demonstrating that treatment was possible through approximately one hundred microns of dense tumor nodules.
