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, ...

When studying biological systems, understanding structure and chemistry often calls for different approaches. Scanning electron microscopy (SEM) is particularly useful for revealing ultrastructural ...

A team has reported a Raman microscopy technique that produced images up to eight times brighter than those achieved with conventional Raman techniques. Imaging of frozen biological samples reduced ...

Researchers from National Taiwan University and collaborators have developed a novel way to observe and monitor carbon dioxide (CO 2) conversion into carbon monoxide (CO) inside living cells, using an ...

Bioengineers bridge the gap between spectroscopy developers and biologists through a systematic guide explaining modern Raman ...

Modern imaging modalities have facilitated a steady progress in medicine and treatment of diseases. Among them, Raman spectroscopy has gained attention for clinical applications as a label-free, ...
