• Miniaturized, multi-spectral optics for tissue differentiation 

  Grygoryev, Konstantin; Lu, Huihui; Sorensen, Simon; Li, Celina L.; Georgel, Rachel; Oâ Hare, Daniel; Burke, Ray; Andersson-Engels, Stefan (Optica Publishing Group, 2022-04)

  Identification of tumour margins during resection of the brain is critical for improving the post-operative outcomes. Present research aims to develop a miniaturized, optical system for simultaneous measurement of DRS and ...
• High contrast breast cancer biomarker imaging using upconverting nanoparticles 

  Sekar, Sanathana K. V.; Ma, Hui; Komolibus, Katarzyna; Dumlupinar, Gokhan; Krawczyk, Krzysztof; Mickert, Matthias; Andersson-Engels, Stefan (Optica Publishing Group, 2022-04)

  Breast cancer is a leading cause of death in women and has scope for improvement in treatment stratification. We report the use of high contrast UCNP staining to distinguish different levels of HER2 expression in HER2 ...
• Theoretical modelling of modulation depth of acoustic optical imaging at varying mechanical properties 

  Gunther, Jacqueline; Jayet, Baptiste; Amissah, Michael; Andersson-Engels, Stefan (Optica Publishing Group, 2022-04)

  The signal from acousto-optical imaging is affected by the mechanical properties of a sample. A theoretical model showed that speed of sound, density, peizooptical coefficient, and acoustic amplitude affect modulation depth.
• Wavelength selection using diffuse reflectance spectra and machine learning algorithms for tissue differentiation in orthopedic surgery 

  Li, Celina L.; Fisher, Carl J.; Komolibus, Katarzyna; Grygoryev, Konstantin; Burke, Ray; Andersson-Engels, Stefan (Optica Publishing Group, 2022-04)

  DRS-based measurements of tissue types encountered in orthopedic surgery are utilized to establish a wavelength selection methodology using machine learning techniques, which enables rapid development of clinically ...
• Non-invasive lung oxygen monitoring in term infants: a pilot trial 

  Panaviene, Jurate; Grygoryev, Konstantin; Pacheco, Andrea; Dempsey, Eugene; Andersson-Engels, Stefan (Optica Publishing Group, 2022-04)

  Employing non-invasive GASMAS based system, lung oxygen measurements were performed on 25 healthy term infants on various chest positions. Oxygen and water vapor absorption signal was detected on most occasions.
