5 / 1000+ results research Multimodal Ion Beam Imaging to Correlate Elements and Metabolites at the Micron Scale Using Water Cluster Secondary Ion Mass Spectrometry and MeV Ion Beam Analysis
This study reported the development of a workflow that combines SIMS and X-ray elemental mapping techniques for multimodal imaging at the single cell level, successfully applied to visualize elements, metals, and lipids in porcine skin without loss or delocalization.
research Dyeing regions of oxidative hair dyes in human hair investigated by nanoscale secondary ion mass spectrometry
This study found that melanin granules in black human hair are key dyeing regions for oxidative hair coloring, as confirmed by nanoscale mass spectrometry analysis detecting deuterium ions.
research Mapping penetration of cosmetic compounds into hair fibers using time‐of‐flight secondary ion mass spectrometry (TOF‐SIMS)
This study found that monounsaturated oils like olive oil penetrate hair fibers effectively, whereas polyunsaturated oils typically do not penetrate beyond the cuticle.
research Ceramide binding to African–American hair fibre correlates with resistance to hair breakage
This study found that a ceramide derived from sphinganine can bind to African–American hair, reducing breakage when applied in a shampoo after relaxing treatments.
