Identification of Natural and Artificial Modifications in DNA at the Nanometer Level

open access: yesJournal of Raman Spectroscopy, Volume 57, Issue 6, Page 995-1007, June 2026.
Short single‐ and double‐stranded DNA sequences with natural and artificial markers are examined at ambient conditions using TERS to identify and localize the labelled nucleobases. The differences between single‐ and double‐stranded DNA should provide clear experimental evidence of the extreme surface sensitivity of TERS.

OCTA-Based Biomarker Characterization in nAMD

open access: yes2025 IEEE 6th International Conference on Image Processing, Applications and Systems (IPAS)
We aim to enhance ophthalmologists' decision-making when diagnosing the Neovascular Age-Related Macular Degeneration (nAMD). We developed three tools to analyze Optical Coherence Tomography Angiography images: (1) extracting biomarkers such as mCNV area and vessel density using image processing; (2) generating a 3D visualization of the ...
