One option is to chemically modify and functionalize 2D materials. However\, many applications require spatially selective functionalization and patterning. Laser-based methods offer many advantages in this regard. A common optical material modification technique is laser ablation. However\, for graphene\, more interesting condition is just below the ablation threshold\, where non-linear excitation of material takes place. Under these conditions\, graphene reacts with adsorbed oxygen and water present in ambient air\, leading to oxidative functionalization without breaking the carbon lattice integrity [1]. Interestingly\, optically induced local functionalization of graphene leads to many opportunities for development of applications via processes such as: modification of electronic properties [1]\, locally selective immobilization of proteins [2\,3]\, area-selective atomic or molecular layer deposition [4\,5]\, modification of optical properties [6]\, tuning of the response of sensors [7]\, or affecting molecular self-assembly [8]. The methods can be applied for development of sensors\, (opto)electronic devices\, flexible and transparent electronics\, bioelectronics\, and so on. \nIn this talk\, I will introduce controlled oxidative functionalization of graphene by femtosecond laser excitation and show several examples of how this method can be used to facilitate development of functional devices. \nReferences[1] J.

Modern biomedical engineering advanced the concept of “reverse engineering”\, which means building micro- and nano-structures with functional biomimicry by extracting design parameters from biological systems\, such as from cell types and shapes\, and from the complex 3D architectures of extracellular matrix microenvironments. Cells seeded on these 3D micro/nano-structures attach\, interconnect\, proliferate\, and finally form masses of cells organized in 3D architectures closely resembling the natural tissue. These micro/nano-structures are currently used not only for fundamental mechanistic studies on the development\, regeneration\, and repair of damaged human tissues\, but also for diagnostics\, disease modeling\, drug delivery\, and personalized medicine. \nIn this talk\, I will present our recent results on the fusion between reverse engineering and laser processing\, within the scope of current challenges in medical treatments. Specifically\, I will show how we “boosted” a conventional 3D printing technique\, known as Laser Direct Writing via Two-Photon Polymerization (LDW via TPP)\, for biomedical engineering. LDW via TPP has been extensively used for fabricating structures with complex 3D architectures\, for biomedical use. It is known that LDW via TPP offers low operational costs\, rapid processing time\, high spatial resolution\, and full reproducibility of the obtained structures\, mandatory for systematic in vitro studies. In our work\, we targeted the development of innovative\, synergistic combinations of 3D micro/nano-structures fabricated by LDW via TPP and specific structure characteristics such as composition\, morphology\, and surface chemistry. This approach allowed us to obtain better control over attachment\, growth\, and\, in some cases\, differentiation of various cell types\, e.g. osteoblasts\, fibroblasts\, and glial cells. We further improved the effectiveness of the laser-printed structures by volumetric integration of electrically and magnetically responsive biomaterials into the “backbone” of the structures. The electrically or magnetically “active” 3D micro/nano-structures allowed us to accelerate certain processes involved in tissue regeneration by externally applied electric or magnetic stimuli. \nWe expect this approach to emerge in advanced biomedical applications such as tissue engineering\, wound dressings\, and advanced drug delivery systems\, with the final goal of refining patient-oriented treatments. \n\n\n \n \n \n \n \n \n \n \n \n \n \n \n \n Watch the Talk URL:https://lasers4.eu/event/laserlab-europe-talk-boosting-multiphoton-3d-printing-for-biomedical-engineering-small-features-high-impact-2-april-2025/ CATEGORIES:Webinars ATTACH;FMTTYPE=image/png:https://lasers4.eu/wp-content/uploads/Thumbnail_paun.png END:VEVENT BEGIN:VEVENT DTSTART;TZID=Europe/Berlin:20250326T170000 DTEND;TZID=Europe/Berlin:20250326T180000 DTSTAMP:20260430T173827 CREATED:20250313T042553Z LAST-MODIFIED:20250710T105035Z UID:4433-1743008400-1743012000@lasers4.eu SUMMARY:Lasers4EU Webinar: Technology transfer and patenting: from fundamental research to a business model.

Rather than simply showcasing successes we will highlight the challenges faced\, including technical\, economic and regulatory barriers and how the company adapted its business model over time.Ultimately the webinar will emphasize the dynamic process of bridging the gap between academic innovation and the business world. \n\n\n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n Watch the webinar URL:https://lasers4.eu/event/lasers4eu-webinar-technology-transfer-and-patenting-from-fundamental-research-to-a-business-model-the-example-of-laserleap-technologies/ CATEGORIES:Webinars ATTACH;FMTTYPE=image/png:https://lasers4.eu/wp-content/uploads/20250326_l4eu_laserleap_linkedin.png END:VEVENT BEGIN:VEVENT DTSTART;TZID=Europe/Berlin:20250305T160000 DTEND;TZID=Europe/Berlin:20250305T170000 DTSTAMP:20260430T173827 CREATED:20250214T105124Z LAST-MODIFIED:20250710T105053Z UID:4264-1741190400-1741194000@lasers4.eu SUMMARY:Laserlab-Europe Talk: Revealing bacterial subcellular structure with three-dimensional multicolour super-resolution microscopy\, 5 March 2025 DESCRIPTION:Speaker: Chiara Caldini (LENS) \nCellular compartmentalization is the separation of the cellular interior into distinct compartments\, each with specific conditions and materials\, that enable the simultaneous execution of different metabolic processes. This organization is essential for regulating cellular functions\, as it enhances efficiency by minimizing the loss of intermediate products. While the compartmentalization of eukaryotic cells is well understood\, much less is known about the prokaryotic one. For a long time\, prokaryotic cells\, such as bacteria\, were believed to lack subcellular organization\, with biochemical reactions occurring in a disordered manner. However\, recent studies on metabolic pathways suggest a certain degree of subcellular organization within bacteria too that would facilitate enzyme proximity to enhance reactions kinetics. Although molecular biology provides different techniques\, such as two-hybrid systems\, to analyse molecular interactions\, imaging approaches are necessary to provide nanoscale spatial information about those interactions. \nIn our work we demonstrate how by combining Photo-Activated Localization Microscopy (PALM) with Expansion Microscopy (ExM) it is possible to perform three-dimensional simultaneous single-molecule co-localization and measure intermolecular distances with nanometres precision. The Ex-PALM approach is applied to study the spatial distribution of two enzymes\, HisF and HisH\, of the histidine metabolic pathway in Escherichia Coli bacteria whose interaction has already been demonstrated by previous studies. Using a plasmid-based transformation\, each protein was tagged with a photoactivable fluorescent protein (HisF-PAGFP\, HisH-PAmCherry) to enable single-molecule localization with nanometres accuracy. A negative control sample with two non-interacting enzymes\, HisH and aaC\, was also prepared to confirm our hypothesis that only interacting proteins co-localize. \nTo validate our theory\, we first improved three-dimensional multicolour PALM imaging by reducing crosstalk and chromatic aberrations. This step was essential\, as these aberrations are comparable in scale to the intermolecular distances of interest\, and failing to correct them would compromise single-molecule localization accuracy\, making it impossible to analyse densely packed subcellular structures\, such as those found in bacteria. Next\, we optimized the ExM protocol to achieve a 4.5-fold isotropic expansion of bacteria\, enabling the study of bacterial subcellular organization. To prove the reliability of our analysis method\, we applied it on both simulated and real data and found consistent results. \n \n Watch the LLE Talk URL:https://lasers4.eu/event/lle-talk-revealing-bacterial-subcellular-structure-with-three-dimensional-multicolour-super-resolution-microscopy/ CATEGORIES:Webinars ATTACH;FMTTYPE=image/png:https://lasers4.eu/wp-content/uploads/Thumbnail_caldini.png END:VEVENT BEGIN:VEVENT DTSTART;TZID=Europe/Berlin:20250305T100000 DTEND;TZID=Europe/Berlin:20250305T120000 DTSTAMP:20260430T173827 CREATED:20250407T105455Z LAST-MODIFIED:20250407T110331Z UID:4583-1741168800-1741176000@lasers4.eu SUMMARY:Lasers4EU Activity Board meeting\, 5 March 2025 DESCRIPTION:The Activity Board of the Lasers4EU project will meet on 5 March 2025\, 10:00-12:00 CET. \nThe link to connect will be shared by the Laserlab-Europe office. \n  \nThis is a project internal event.

These electrodes have been found to exhibit enhanced electrochemical properties and they have been used in water-splitting electrochemical cells where we have found that they produce almost 5 times as much Hydrogen when compared with flat metallic electrodes. The enhanced Hydrogen evolution reactivity and electrochemical properties are attributed to the concomitant enlargement of the electrode’s electrocatalytic area due to the nanostructured surface. The details of the experiments as well as the impact of applications of lasers in the energy and environmental sectors will be discussed.\n \n Watch the Talk\n \n \n \n \n \n This Laserlab-Europe Talk is coorganised by Lasers4EU and 360Carla.

Ohland (GSI Helmholtz Center for Heavy Ion Research)Date: Wednesday\, 18 December 2024\, 16:00 CET \nThe Apollon Real-Time Adaptive Optics (ARTAO) system addresses air turbulence-induced Strehl ratio fluctuations in Apollon\, the 10 PW Ti:Sapphire laser system in France. With a 50 m multi-pass amplifier and a 140 mm beam diameter\, turbulence previously caused significant beam quality instability. To resolve this\, the open-source AO platform CACAO\, originally developed for the Subaru Observatory\, was adapted for real-time beam stabilization using a continuous pilot beam. This marks a pioneering application of astronomical AO technology in ultra-high-intensity lasers. \nSupported by the EC funded THRILL project under its wavefront stabilization task\, ARTAO demonstrates a stability sufficient to achieve an on-shot Strehl ratio above 0.96 by evaluating 2.6 thousand wavefronts per second and controlling a deformable mirror at 1.3 kHz. \nThis technology has great potential for future applications: in Inertial Confinement Fusion (ICF) powerplants\, real-time AO will be indispensable for operating hundreds of laser beamlines at 10 Hz\, delivering MJ-scale pulses with minimal aberrations. By integrating AO into Adaptive Laser Architecture (ALA)\, these systems can overcome thermal challenges and meet the demands of fusion energy production. \nThis presentation will detail ARTAO’s development\, initial results\, and its potential role in the future of high-energy laser systems. \n \n Watch the LLE Talk URL:https://lasers4.eu/event/laserlab-europe-talk-from-telescopes-to-fusion-powerplants-real-time-adaptive-optics-for-high-power-lasers/ CATEGORIES:Webinars ATTACH;FMTTYPE=image/png:https://lasers4.eu/wp-content/uploads/Thumbnail-Ohland.png END:VEVENT BEGIN:VEVENT DTSTART;TZID=Europe/Berlin:20241120T160000 DTEND;TZID=Europe/Berlin:20241120T170000 DTSTAMP:20260430T173827 CREATED:20241107T121429Z LAST-MODIFIED:20250710T105332Z UID:2977-1732118400-1732122000@lasers4.eu SUMMARY:Laserlab-Europe Talk: Compressive Raman imaging: a computational framework for high-speed chemical microscopy DESCRIPTION:Title: Compressive Raman imaging: a computational framework for high-speed chemical microscopySpeaker: Hilton B. de Aguiar (CNRS\, Laboratoire Kastler Brossel and Ecole Normale Superieure)Date: Wednesday\, 20 November 2024\, 4:00pm CET \nRaman imaging is recognized as a powerful label-free approach to provide contrasts based on chemical selectivity. Nevertheless\, Raman-based microspectroscopy still have drawbacks precluding high-speed chemical imaging. The main issue is the inherent high data throughput in microspectroscopy: fast spectral imaging is challenging for dynamic and large-scale imaging due to its data acquisition\, processing and representation change (from vibrational resonances amplitudes to chemicals concentration) procedures. \nThese challenges can be overcome by exploiting the concept of compressive Raman imaging: by leveraging the sparsity [1] and redundancy [2] in Raman data sets\, one can develop computational procedures to considerably simplify and speed up the spectral image acquisition. Exploiting such framework\, we have recently reached speeds compatible with video-rate imaging [3] by detecting just a handful of photons. \nIn this presentation\, I will introduce and discuss the different ways of performing compressive Raman\, in particular focusing on challenges for bio-imaging\, and also show more recent results applied to long-time imaging of electrochemical systems [4]. \nReferences[1] Sturm et al\, ACS Photon. 6\, 1409 (2019); Scotte et al.

Among the various enabling tools\, electronic laboratory notebooks (ELNs) – designed to replace commonly used paper notebooks – offer notable benefits to users\, from supporting collaboration amongst researchers\, simplifying secured copying of data or time stamping to directly incorporating of instrument parameters. However\, there are a multitude of ELN products on the market [Nature Protocols 17\, 179 (2022)] and identifying the most appropriate and user-friendly one may be complex and time-consuming. \nThis Laserlab-Europe online workshop will present user experience (pros and cons) on some of the most popular ELNs (e.g. eLabFTW or Labfolder) as well as national initiatives on related topics such as metadata. Discussions will allow exchanging on pros and cons of ELNs and on how to motivate ourselves to switch from paper to an ELN. \nAgenda >> \n\n Notice: JavaScript is required for this content.\n\n\n \n\n\n \n \n \n  \n  URL:https://lasers4.eu/event/workshop-on-electronic-laboratory-notebooks/ CATEGORIES:Project END:VEVENT BEGIN:VEVENT DTSTART;TZID=Europe/Berlin:20241021T070000 DTEND;TZID=Europe/Berlin:20241022T160000 DTSTAMP:20260430T173827 CREATED:20240807T083601Z LAST-MODIFIED:20241202T073528Z UID:1872-1729494000-1729612800@lasers4.eu SUMMARY:Lasers4EU Kick-off Meeting\, 21-22 October 2024\, Crete\, Greece DESCRIPTION:Preliminary agenda \n21 October 2024\n09:00-13:00 Laserlab-Europe V General Assembly\n13:00-14:00 Lunch\n14:00-17:30 Lasers4EU Kick-off Meeting Day 1\n17:30-19:00 Lab Tour at IESL-FORTH\n19:30- Working Dinner \n22 October 2024\n09:00-15:30 Lasers4EU Kick-off Meeting Day 2\n16:00/16:30 Sightseeing Tour \n\n Notice: JavaScript is required for this content.
