Microplastics—plastics particles smaller than 5 mm in size—have caused an environmental pollution issue that cannot be ignored by our society. Raman spectroscopy technology, with its non-contact, ...

A nonlinear coherent Raman method now enables direct, high sensitivity detection without such requirements. A time-frequency engineered optical design suppressed strong substrate background signals by ...

Stimulated Raman Scattering (SRS) has been developed as an essential quantitative contrast for chemical imaging in recent years. However, the spectral resolution of the mainstream SRS modalities is ...

The field of forensic science is continually advancing as it integrates newer and more reliable analytical technologies. The landscape of illicit drug detection is ever-changing, with yearly shifts ...

Lead is a highly toxic and persistent heavy metal that poses serious risks to human health. The detection of lead ions in ...
