Two-photon (2P) microscopy is widely used in neuroscience, but the optical properties of brain tissue are poorly understood. We have investigated the effect of brain tissue on the 2P point spread function (PSF2P) by imaging fluorescent beads through...

Improved method for kinetic studies in microreactors using flow manipulation and noninvasive Raman spectrometry. Journal of the American Chemical Society, 133(10), 3601-3608. https://doi.org/10.1021/ja1102234

A novel method has been devised to derive kinetic information about reactions in microfluidic systems. Advantages have been demonstrated over conventional procedures for a Knoevenagel condensation reaction in terms of the time required to obtain the...

The quantitative measurement of particle motion in optical tweezers is an important tool in the study of microrheology and can be used in a variety of scientific and industrial applications. Active microheology, in which the response of optically tra... Read More about Multidepth, multiparticle tracking for active microrheology using a smart camera.

Adaptive optics for wide-field microscopy (2011)
Presentation / Conference Contribution
Bourgenot, C., Saunter, C., Girkin, J., & Love, G. (2011). Adaptive optics for wide-field microscopy. . https://doi.org/10.1117/12.873857

We report on recent developments in the use of adaptive optics (AO) in wide-field microscopy to remove both system and sample induced aberrations. We describe progress on using both a full AO system and image optimization techniques (wavefront sensor... Read More about Adaptive optics for wide-field microscopy.

Heart synchronization for SPIM microscopy of living zebra fish (2011)

We describe work on producing a selective plane illumination microscope for cardiac imaging in zebra fish embryos. The system has a novel synchronization system for imaging oscillating structures (e.g. the heart) and will have adaptive optics for ima...
