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

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 …

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.

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

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  

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, …

  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).....
