If you make tiny imaging fibres with *ordered* core structure, does that impact how they image? We aimed to find out... nice work by Helen Parker: https://osapublishing.org/ol/fulltext.cfm?uri=ol-45-23-6490&id=444064 In Optics Letters. A reminder how we use these fibres for endoscopy: https://tanner-lab.org/2019/04/01/ratiometric-spectral-imaging-through-fibre-to-make-the-bacteria-shine/ https://www.osapublishing.org/boe/fulltext.cfm?uri=boe-10-4-1856&id=407395
Time resolved investigation of tiny fibre fluorescent probes (the ones we use to measure deep in the lung)
Great work from Katjana getting this time resolved spectroscopy paper out. https://doi.org/10.3390/s20216115 In MDPI Sensors We highly load fluorophores onto optical fibres for medical sensing, but when you pack in a lot of fluorophore the behaviour gets complex. How to investigate? We use our favourite technique, time resolved spectroscopy! Direct observation of the energy transfer …
Molecular detection of Gram-positive bacteria in the human lung through an optical fiber–based endoscope
A large long running collaborative effort on this one.... https://doi.org/10.1007/s00259-020-05021-4 Observing the presence of bacteria through our custom made fibre endoscope (the one mentioned in other posts).Optics, biology, clinicians.... it's all there.
Laser Focus World article – Ultrafast-laser ablation of polymer multicore fibers enhances biomedical sensing
https://www.laserfocusworld.com/fiber-optics/article/14177491/ultrafastlaser-ablation-of-polymer-multicore-fibers-enhances-biomedical-sensing Nice article summarising the work of Hari and Eunan on laser ablation of polymer fibres (as presented by Eunan at OSA Biophotonics in April)
I love the video in our new paper: Observing mode-dependent wavelength-to-time mapping in few-mode fibers using a single-photon detector array

A neat way to attach fluorophores where you want on the end of a multicore fibre:
OSA Biophotonics Congress: Biomedical Optics
My first fully online conference..... it worked well. I missed all the interaction and networking, but it was great to be able to dip into high quality talks in between home schooling..... we had a few talks, I hope people enjoyed them! https://www.osapublishing.org/abstract.cfm?uri=Translational-2020-TTu2B.4 https://www.osapublishing.org/abstract.cfm?uri=Translational-2020-TM2B.5 https://www.osapublishing.org/abstract.cfm?uri=Translational-2020-TW2B.2 https://www.osapublishing.org/abstract.cfm?uri=Translational-2020-TTu2B.3 https://www.osapublishing.org/abstract.cfm?uri=Translational-2020-TTu2B.2
Cheap lenses for smartphone fluorescence microscopy
Good work by Jo, Helen and Katjana (and minimal input from the rest of us). A nice way to develop cheap lenses for use with smartphones....... https://doi.org/10.1364/BOE.381014
A tiny fibre sensor for measuring conditions in the lung….
Very happy this is finally published, it's taken a while..... I think this work really well describes the combination of technologies across a collaboration to do something really nice (and it looks kind of cool!) A few of my notes on the content below: High fidelity fibre-based physiological sensing deep in tissue Scientific Reports, …

Healthcare Innovation and Technologies Festival at Heriot-Watt
Having fun networking at the Healthcare Innovation and Technologies Festival at Heriot-Watt - and the media guy took a nice photo! https://www.hw.ac.uk/about/news/2019/hit-research-festival-opens.htm hit-festival.org PS, Helen won the poster prize again (obvously).....
