Stimulated emission depletion microscopy with a supercontinuum source and fluorescence lifetime imaging

Auksorius, E; Boruah, BR; Dunsby, C; Lanigan, PMP; Kennedy, G; Neil, MAA; French, PMW

We demonstrate stimulated emission depletion (STED) microscopy implemented in a laser scanning confocal microscope using excitation light derived from supercontinuum generation in a microstructured optical fiber. Images with resolution improvement beyond the far-field diffraction limit in both the l...

Phytoplankton composition and selective feeding of the pearl oyster Pinctada margaritifera in the Takapoto lagoon (Tuamotu Archipelago, French Polynesia): in situ study using optical microscopy and HPLC pigment analysis

Loret P; Pastoureaud Annie; Bacher Cedric; Delesalle B

The in situ diet of the pearl oyster Pinctada margarifera was determined in the lagoon of Takapoto Atoll by comparing the phytoplankton composition of water and bivalve gut contents using 2 different methods, optical microscopy and HPLC pigment analysis. In order to evaluate the available food resou...

Multifocal multiphoton excitation and time correlated single photon counting detection for 3-D fluorescence lifetime imaging

Kumar, S; Dunsby, C; De Beule, PAA; Owen, DM; Anand, U; Lanigan, PMP; Benninger, RKP; Davis, DM; Neil, MAA; Anand, P; Benham, C

We report a multifocal multiphoton time-correlated single photon counting (TCSPC) fluorescence lifetime imaging (FLIM) microscope system that uses a 16 channel multi-anode PMT detector. Multiphoton excitation minimizes out-of-focus photobleaching, multifocal excitation reduces non-linear in-plane ph...

High speed optically sectioned fluorescence lifetime imaging permits study of live cell signaling events

Grant, DM; McGinty, J; McGhee, EJ; Bunney, TD; Owen, DM; Talbot, CB; Zhang, W; Kumar, S; Munro, I; Lanigan, PMP; Kennedy, GT

We present a time domain optically sectioned fluorescence lifetime imaging (FLIM) microscope developed for high-speed live cell imaging. This single photon excited system combines wide field parallel pixel detection with confocal sectioning utilizing spinning Nipkow disc microscopy. It can acquire f...

Fluorescence lifetime imaging by using time-gated data acquisition

Soloviev, VY; Tahir, KB; McGinty, J; Elson, DS; Neil, MAA; French, PMW; Arridge, SR

The use of the time gating technique for lifetime reconstruction in the Fourier domain is a novel technique. Time gating provides sufficient data points in the time domain for reliable application of the Fourier transform, which is essential for the time deconvolution of the system of the integral e...

An electronically tunable ultrafast laser source applied to fluorescence imaging and fluorescence lifetime imaging microscopy

Lanigan, PMP; Dunsby, C; McGinty, J; Elson, DS; Requejo-Isidro, J; Munro, I; Galletly, N; Treanor, B; Onfelt, B; McCann, F

We demonstrate that spectral selection from a supercontinuum generated in a microstructured fibre can provide a continuously electronically tunable ultrafast spatially coherent source for confocal microscopy and both scanning and wide field fluorescence lifetime imaging.

An electronically tunable ultrafast laser source applied to fluorescence imaging and fluorescence lifetime imaging microscopy

Dunsby, C; Lanigan, PMP; McGinty, J; Elson, DS; Requejo-Isidro, J; Munro, I; Galletly, N; McCann, F; Treanor, B; Onfelt, B

Fluorescence imaging is used widely in microscopy and macroscopic imaging applications for fields ranging from biomedicine to materials science. A critical component for any fluorescence imaging system is the excitation source. Traditionally, wide-field systems use filtered thermal or arc-generated ...
