McConnell G, Mabbott S, Kanibolotsky A, Skabara P, Graham D, Burley G, et al.
Langmuir . 2018 Sep; 34(49):14766-14773. PMID: 30227713
Organic semiconductor lasers are a sensitive biosensing platform that respond to specific biomolecule binding events. So far, such biosensors have utilized protein-based interactions for surface functionalization but a nucleic acid-based...

J Microsc . 2018 Mar; 270(2):252-258. PMID: 29570774
In a previous paper, we showed a new giant lens called the Mesolens and presented performance data and images from whole fixed and intact fluorescently-stained 12.5-day old mouse embryos. Here,...

Tinning P, Franssen A, Hridi S, Bushell T, McConnell G
J Microsc . 2017 Aug; 269(3):212-220. PMID: 28837217
We report the first demonstration of a fast wavelength-switchable 340/380 nm light-emitting diode (LED) illuminator for Fura-2 ratiometric Ca imaging of live cells. The LEDs closely match the excitation peaks...

Tragardh J, Robb G, Amor R, Amos W, Dempster J, McConnell G
J Microsc . 2015 May; 259(3):210-8. PMID: 25946127
We have studied the wavelength dependence of the two-photon excitation efficiency for a number of common UV excitable fluorescent dyes; the nuclear stains DAPI, Hoechst and SYTOX Green, chitin- and...

Tragardh J, Macrae K, Travis C, Amor R, Norris G, Wilson S, et al.
J Microsc . 2015 Apr; 259(1):66-73. PMID: 25864964
We report a method for characterizing the focussing laser beam exiting the objective in a laser scanning microscope. This method provides the size of the optical focus, the divergence of...

Travis C, Norris G, McConnell G, Oppo G
Opt Express . 2013 Oct; 21(20):23459-70. PMID: 24104260
Self-focusing of intense laser beams and pulses of light in real nonlinear media is in general accompanied by material losses that require corrections to the conservative Nonlinear Schrödinger equations describing...

Norris G, Amor R, Dempster J, Amos W, McConnell G
J Microsc . 2012 Oct; 248(2):200-7. PMID: 23078118
We report the use of an all-solid-state ultrashort pulsed source specifically for two-photon microscopy at wavelengths shorter than those of the conventional Ti:Sapphire laser. Our approach involves sum-frequency mixing of...

Amor R, Norris G, Dempster J, Amos W, McConnell G
Rev Sci Instrum . 2012 Sep; 83(8):083705. PMID: 22938301
Biomedical imaging applications that involve nonlinear optical processes such as sum-frequency generation (SFG) and four-wave mixing require that the pulses are synchronized in time and the beams are coaxial to...

Power S, Kavanagh D, McConnell G, Cronin K, Corish C, Leonard M, et al.
Ir J Med Sci . 2011 Oct; 181(1):99-104. PMID: 21959951
Background: The practice of fasting from midnight prior to surgery is an outdated one. Aims: The aim of this study was to assess the impact of an evidence-based protocol for...

Opt Express . 2010 Apr; 18(5):3993-9. PMID: 20389413
A novel bi-directional pump geometry that nonlinearly increases the nonlinear optical conversion efficiency of a synchronously pumped optical parametric oscillator (OPO) is reported. This bi-directional pumping method synchronizes the circulating...
