Recent Highlights

Our work on Polydimethylsiloxane Composites for Optical Ultrasound Generation and Multimodality Imaging was featured on the cover of Advanced Functional Materials . The work was carried out in collaboration with Dr Adrien Desjardin's group in Medical Physics. In this paper, we give an overview of the various methods used to incorporate pigments into polydimethylsiloxane (PDMS) coatings, and present two novel PDMS composites that enable dual modality (optical ultrasound + photoacoustic) imaging using miniature, fibre-optic probes. The efficacy of such probes on both ex vivo swine tissue and ex vivo diseased human aorta tissue was also demonstrated.

 

Our work on ultrasensitive plano-concave optical microresonators for ultrasound imaging has been published in Nature Photonics. The work carried out in collaboration with Prof. Paul Beard's and Dr Adrien Desjardin's groups, both in Medical Physics, demonstrated highly sensitive miniaturised ultrasound receivers that can transform minimally invasive operations. 

 

The first demonstration of in vivo tissue visualisation with our all-optical ultrasound transducer was published in the journal Nature: Light Science & Applications. The work was carried out with collaborators from the St Bart's Hospital and UCL Departments of Medical Physics and Chemistry.  

 

SERSOur study on Surface-Enhanced Raman Spectroscopy to detect low vapour pressure gases has been published in Nanoscale. The work carried out in collaboration with Prof. Ivan Parkin's group in Chemistry demonstrated highly sensitive SERS substrates by using silver nanocubes with very low limit-of-detection for explosive materials. 

 

Our study on the Impact of curvature on the optimisation of luminescent solar concentrators has been published in Optics Letters. The letter discusses how optimal LSC concentrations can vary by a factor of two for bent or flat configurations. The paper was selected as an Editor's pick.

 

Our work on novel optical ultrasound transmitters has been published in Applied Physics Letters. This is the first time electrospinning has been reported on an optical fibre endface. This can be used in novel optical fibre sensors and lab-on-fibre applications.

 

Our study exploring the linking of organic dyes and inorganic quantum dots has been published in the journal Nano Energy. We show experimentally to which extent the linking of inorganic, broadband absorbers to high quantum-yield organic emitters enhances the performance of a luminescent solar concentrator.
