A fatty-acid based probe for near-infrared fluorescence guided surgery of glioblastoma
Elena Goun, Pavlo Khodakivskyi
High-grade gliomas (HGG) are the most common and most aggressive primary tumors of the brain. Despite recent advances in neuro-oncology survival of these tumors remains around 12-15 months. The first-line of treatment is surgical resection. However, due to ...
Spie-Int Soc Optical Engineering2024Remote wide angle view broad wavelength viewing system compatible with D-T operations in JET
Gilles Arnoux, Paulo Giovane Paschoali Pereira Puglia
Imaging diagnostics in Joint European Torus have become essential in the study of plasma wall interactions and the protection of the plasma facing components. During deuterium operations, the location of these diagnostics was at close proximity to the vess ...
2023Correlated-photon imaging at 10 volumetric images per second
Edoardo Charbon, Claudio Bruschini, Paul Mos, Arin Can Ülkü
The correlation properties of light provide an outstanding tool to overcome the limitations of traditional imaging techniques. A relevant case is represented by correlation plenoptic imaging (CPI), a quantum-inspired volumetric imaging protocol employing s ...
NATURE PORTFOLIO2023LenslessPiCam: A Hardware and Software Platform for Lensless Computational Imaging with a Raspberry Pi
Martin Vetterli, Eric Bezzam, Sepand Kashani, Matthieu Martin Jean-André Simeoni
This toolkit has everything you need to perform imaging with a lensless camera. We make use of a low-cost implementation of DiffuserCam, namely replacing the lens with a piece of tape and using the Raspberry Pi HQ camera sensor. Similar principles and meth ...
Zenodo2023Resolution and penetration depth of reflection-mode time-domain near infrared optical tomography using a ToF SPAD camera
Edoardo Charbon, Martin Wolf, Jingjing Jiang
In a turbid medium such as biological tissue, near-infrared optical tomography (NIROT) can image the oxygenation, a highly relevant clinical parameter. To be an efficient diagnostic tool, NIROT has to have high spatial resolution and depth sensitivity, fas ...
Optica Publishing Group2022Photoresponsive Nanocarriers Based on Lithium Niobate Nanoparticles for Harmonic Imaging and On-Demand Release of Anticancer Chemotherapeutics
Sandrine Gerber, Jérémy Vuilleumier, Adrian Stefan Gheata, Dario Diviani, Luigi Bonacina, Simon Kaiser
Nanoparticle-based drug delivery systems have the potential for increasing the efficiency of chemotherapeutics by enhancing the drug accumulation at specific target sites, therebyreducing adverse side effects and mitigating patient acquired resistance. In ...
2022Optical spectroscopy of earth-abundant zinc pnictides for photovoltaics
Zinc phosphide (Zn3P2) is an earth-abundant semiconductor with promising properties for applications as an absorber in photovoltaics. To beat the 40 years old record power conversion efficiency of solar cells made with this material, a deep understanding o ...
EPFL2022Ultrafast X-ray Spectroscopy of Haem Proteins
Majed Chergui, Camila Bacellar Cases Da Silveira
In this article we revisit our recent picosecond and femtosecond X-ray absorption spectroscopy (XAS) and X-ray emission spectroscopy (XES) experiments, probing the ultrafast electronic and geometric evolution of photoexcited haem proteins, namely ferrous N ...
SWISS CHEMICAL SOC2022Spatio-Temporal Dynamics of Free and Bound Carriers in Photovoltaic Materials
Jacques-Edouard Moser, George Cameron Fish
Photoinduced charge separation into free carriers and subsequent charge transfer are key processes that govern the efficiencies of third generation solar cell technologies based on donor-acceptor heterojunctions. As these processes typically occur on picos ...
2022Superluminal Motion-Assisted Four-Dimensional Light-in-Flight Imaging
Edoardo Charbon, Andrei Ardelean, Ming-Lo Wu, Kazuhiro Morimoto
Advances in high-speed imaging techniques have opened new possibilities for capturing ultrafast phenomena such as light propagation in air or through media. Capturing light in flight in three-dimensional xyt space has been reported based on various types o ...
