Abstract DNA double strand breaks (DSBs) are deadly lesions that can lead to genetic defects and cell apoptosis. Techniques directly detect DSBs include scanning electron microscopy, atomic force microscopy (AFM), fluorescence based approaches. While these techniques be used identify they provide no information on the molecular events occurring at break. Tip‐enhanced Raman scattering (TERS) from nanoscale in combination with AFM provides a new way visualize characterize structure of DSBs....

Lipid droplets (LDs) are key organelles in cancer cells proliferation, growth, and response to stress. These nanometric structures can aggregate reach the size of microns becoming important cell components. Although it is known that LDs contain various lipids, their chemical composition still under investigation. Moreover, function cell's exogenous factors also not fully understood. Raman spectroscopy, together with chemometrics, has been shown be a powerful tool for analytical analyses...

Abstract The recent emergence of High Definition (HD) FT-IR and Quantum Cascade Laser (QCL) Microscopes elevated the IR imaging field very close to clinical timescales. However, speed acquisition data quality are still critical factors in reaching clinic. Denoising offers aide both aspects if performed properly. there is a lack direct comparison efficiency denoising techniques general. To achieve such within rigorous framework obtaining information about signal loss, simulated dataset...

Abstract Spore-forming bacteria are a class of microorganisms that possess the ability to survive in extreme environmental conditions. Morphological features spores assure their resistance stress factors such as high temperature, radiation, disinfectants, and drying. Consequently, spore elimination industrial medical environments is very challenging. Ceragenins new cationic lipids characterized by broad spectrum bactericidal activity resulting from amphipathic nature membrane-permeabilizing...

Abstract OLED technology beyond small or expensive devices requires light-emitters, luminophores, based on earth-abundant elements. Understanding and experimental verification of charge transfer in luminophores are needed for this development. An organometallic multicore Cu complex comprising Cu–C Cu–P bonds represents an underexplored type luminophore. To investigate the structural rearrangements material, we apply complementary pump-probe X-ray techniques: absorption, emission, scattering...
