WITec Paper Awards 2025: Battery, biomedical and crystal research recognised
Oxford Instruments has announced the winners of the WITec Paper Award 2025, celebrating outstanding scientifi c publications that showcase the power and versatility of Raman microscopy. This year’s awards highlight innovative research from Germany and Poland, demonstrating how Raman imaging continues to unlock new possibilities in material science, energy storage, and biomedical diagnostics.
combines confocal Raman microscopy with nanoindentation to create in operando 3D maps of elastic deformation fi elds - capturing subsurface strain behaviour with unprecedented clarity. Applied to calcite-based materials, the technique revealed how these fi elds evolve and eventually transition into inelastic deformations. The researchers see 3D-RISM as a valuable tool for studying the mechanical performance of complex and hybrid materials at the microscale.
The Silver Award, ‘Elucidating the nature of secondary phases in LiNi₀.₅Mn₁.₅O₄ cathode materials using correlative Raman-SEM microscopy’, went to Umair Nisar and his team at the Centre for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW) for their work on lithium-ion battery cathodes. Focusing on LiNi₀.₅Mn₁.₅O₄ (LNMO), a cobalt-free cathode material, the group used correlative Raman and SEM microscopy to investigate the secondary phases that form during high-temperature synthesis. While standard characterisation methods like XRD struggled to resolve these phases, Raman imaging enabled the detection of three distinct secondary phases - identifi ed for the fi rst time in LNMO calcined at 1000°C. Their fi ndings revealed a link between these unwanted phases and reduced discharge capacity, providing critical insight for improving next-generation battery materials.
The Paper Award Bronze goes to Dr Patrycja Leszczenko and her team from the Jagiellonian University in Krakow, Poland, with the award presented by Maxime Tchaya from Oxford Instruments.

The Paper Award 2025 Gold winner Dr. Shahrouz Amini (left) from the Max Planck Insti tute of Colloids and Interfaces in Potsdam, Germany receives his Award from Oxford Instruments representative Thomas Olschewski.
Taking the Gold Award, ‘In operando 3D mapping of elastic deformation fi elds in crystalline solids’, Shahrouz Amini and colleagues at the Max Planck Institute of Colloids and Interfaces in Potsdam developed a novel technique to observe how crystalline solids respond to pressure in real time. Their method, called 3D-RISM,
spectroscopy for precise single-cell phenotyping and subtype classification’, recognised Patrycja Leszczenko and colleagues from Jagiellonian University in Krakow for their work in leukaemia diagnostics. Their study explored how label-free Raman spectroscopy, combined with statistical methods such as PCA and PLS-DA, could distinguish between healthy and malignant cells in cases of acute lymphoblastic leukaemia (ALL). The technique proved capable of differentiating B-cell and T-cell subtypes at the single-cell level, even across varied sample preparation methods. The team believes this approach could offer a faster, more reliable alternative to conventional diagnostic workflows - bringing personalised treatment closer to reality for ALL patients.

Meanwhile, the Bronze Award, ‘Advancing triage of acute lymphoblastic leukaemia subtypes diagnosis: label-free Raman
2025 Innovation Award highlights advances in multi-photon microscopy
Toptica has been honoured with the 2025 Laser World of Photonics Innovation Award in the Biophotonics and Medical Engineering category. The award, organised by Europa Science Ltd, recognises technologies making a signifi cant impact on both research and clinical imaging.
The winning femtosecond laser system simplifies multi-photon microscopy by automating femtosecond fibre delivery, improving safety and operational ease in bioimaging laboratories. According to Toptica, the technology allows researchers to focus
on experiments rather than complex beam alignment.
Supporting widely used imaging wavelengths and compatible with standard fl uorophores, the platform is optimised for deep- tissue imaging and nonlinear excitation techniques, highlighting its relevance to modern microscopy workfl ows.
