In conservation science, the identification of painting materials is fundamental for the study of artists’ palettes, for dating and for understanding on-going degradation phenomena. For these purposes ...

When cancer is detected early, treatments are more effective and survival improves. Current diagnostic modalities of imaging (e.g., ultrasound, CT, MRI, PET) and solid biopsy with pathology and ...

A Raman spectroscopy system uses a laser to illuminate a target sample and a spectrometer to detect inelastic light scattering. The scattered light is displaced in wavelength from the laser emission ...

At its simplest, Raman spectroscopy is a light-scattering technique. When monochromatic light, usually from a laser, hits a sample, most of it returns unchanged. But a small portion scatters ...

Laser wavelength selection, a critical determinant of accuracy and data quality, is guided by factors such as resonance, fluorescence, and sample absorption. Ensuring the correct laser wavelength ...
