Journal ArticleDOI
Colloidal quantum dot nanocomposites for visible wavelength conversion of modulated optical signals
Nicolas Laurand,Benoit Guilhabert,Jonathan J. D. McKendry,Anthony Kelly,Bruce Rae,David Massoubre,Zheng Gong,Erdan Gu,Robert Henderson,Martin D. Dawson +9 more
TL;DR: In this paper, the steadystate and optical modulation characteristics of a luminescence down-converting colloidal quantum dot/polyimide nanocomposite system suitable for integration with gallium nitride optoelectronics were evaluated at wavelengths from 535 to 624 nm.
Journal ArticleDOI
Cylindrical microlensing for enhanced collection efficiency of small pixel SPAD arrays in single-molecule localisation microscopy
Istvan Gyongy,Amy Davies,Benjamin Gallinet,Neale Dutton,Rory R. Duncan,Colin Rickman,Robert Henderson,Paul A. Dalgarno +7 more
TL;DR: The first characterisation of a cylindrical-shaped microlens array applied to a small, 8 micron, pixel SPAD imager is presented, and the enhanced fill factor, ≈50% for collimated light, is the highest reported value amongst SPAD sensors with comparable resolution and pixel pitch.
Journal ArticleDOI
Real-time fluorescence lifetime actuation for cell sorting using a CMOS SPAD silicon photomultiplier
Francescopaolo Mattioli Della Rocca,Jakub Nedbal,David Tyndall,Nikola Krstajić,David Day-Uei Li,Simon Ameer-Beg,Simon Ameer-Beg,Robert Henderson +7 more
TL;DR: A single-point digital silicon photomultiplier (SiPM) detector accomplishing real-time fluorescence lifetime-activated actuation targeting cell sorting applications in flow cytometry and burst-integratedfluorescence lifetime (BIFL) detection by TCSPC is presented.
Journal ArticleDOI
Time-resolved multifocal multiphoton microscope for high speed FRET imaging in vivo
Simon P. Poland,Simon P. Poland,Nikola Krstajić,Simao Coelho,David Tyndall,Richard Walker,Viviane Devauges,Viviane Devauges,Penny E. Morton,Penny E. Morton,Nicole S. Nicholas,Nicole S. Nicholas,Justin Richardson,David Day-Uei Li,Klaus Suhling,Claire M. Wells,Madeline Parsons,Robert Henderson,Simon Ameer-Beg,Simon Ameer-Beg +19 more
TL;DR: A diffraction limited, massively parallel, time-resolved multifocal multiphoton microscope capable of producing fluorescence lifetime images with 55 ps time-resolution is presented, giving improvements in acquisition speed of a factor of 64.
Proceedings ArticleDOI
A Microsystem for Time-Resolved Fluorescence Analysis using CMOS Single-Photon Avalanche Diodes and Micro-LEDs
Bruce Rae,C. Griffin,K.R. Muir,John M. Girkin,Erdan Gu,D.R. Renshaw,Edoardo Charbon,Martin D. Dawson,Robert Henderson +8 more
TL;DR: There is a growing interest in time-resolved fluorescence detection, whereby the characteristic fluorescence decay time-constant in response to an impulse excitation source is measured.
