We present a time-gated Raman micro-spectroscopy technique suitable for fast Raman mapping of samples eliciting large laser-induced fluorescence backgrounds. To achieve the required time resolution for effective fluorescence rejection, a picosecond p...

Holographic optical trapping Raman micro-spectroscopy for non-invasive measurement and manipulation of live cells (2018)
Journal Article

We present a new approach for combining holographic optical tweezers with confocal Raman spectroscopy. Multiple laser foci, generated using a liquid-crystal spatial light modulator, are individually used for both optical trapping and excitation of sp...

Optical sectioning in multi-foci Raman hyperspectral imaging (2018)
Journal Article
Liao, Z., Sinjab, F., Elsheikha, H. M., & Notingher, I. (2018). Optical sectioning in multi-foci Raman hyperspectral imaging. Journal of Raman Spectroscopy, 49(10), 1660-1667. https://doi.org/10.1002/jrs.5450

In this study, we compared the depth-discrimination and speed performance of multi-foci Raman hyperspectral imaging with the reference standard of a single laser point confocal Raman mapping. A liquid crystal spatial light modulator (LC-SLM) was empl... Read More about Optical sectioning in multi-foci Raman hyperspectral imaging.

Intra-operative spectroscopic assessment of surgical margins during breast conserving surgery (2018)
Journal Article
Shipp, D. W., Rakha, E. A., Koloydenko, A. A., Macmillan, R. D., Ellis, I. O., & Notingher, I. (2018). Intra-operative spectroscopic assessment of surgical margins during breast conserving surgery. Breast Cancer Research, 20, https://doi.org/10.1186/s13058-018-1002-2

Background: In over 20% of breast conserving operations, postoperative pathological assessment of the excised tissue reveals positive margins, requiring additional surgery. Current techniques for intra-operative assessment of tumor margins are insuff... Read More about Intra-operative spectroscopic assessment of surgical margins during breast conserving surgery.

Holographic optical trapping Raman micro-spectroscopy for interacting live cells (2018)
Working Paper
Sinjab, F., Elsheikha, H. M., Awuah, D., Gibson, G., Padgett, M., Ghaemmaghami, A. M., & Notingher, I. Holographic optical trapping Raman micro-spectroscopy for interacting live cells

We present a combined holographic optical tweezers and confocal Raman spectroscopy instrument which allows fast, flexible, and interactive manipulation with molecular measurement of interacting live cell systems. Multiple laser foci created using a s... Read More about Holographic optical trapping Raman micro-spectroscopy for interacting live cells.
