  Wide-field three-photon excitation in biological samples

  , 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.

  Near-infrared temporal focusing microscopy with quantum dot fluorophores

  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.

  3D-resolved targeting of photodynamic therapy using temporal focusing

  , 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.
