Discrimination of Bacterial Growth Media Using Portable Raman Spectroscopy with Background Fluorescence Subtraction


We investigated the feasibility of identifying different types of bacterial growth medium using a handheld Raman instrument with a proprietary baseline correction algorithm. Our data suggest that this instrument is capable of differentiating multiple types of growth medium and readily detects the change in the Raman signal when bacteria are present in the growth medium. These findings support the notion that a handheld Raman spectrometer may be used to distinguish highly-fluorescent biological samples without the use of surface-enhanced Raman scattering.

Atoms Don't Lie: Inside the Quiet Revolution Remaking Atomic Spectroscopy
Atomic spectroscopy has quietly gone from counting elements in bulk to counting single nanoparticles, imaging tissue at the micrometer scale, and reading Martian rocks from several meters away. The instruments got smaller, the software got smarter, and the questions they can now answer got a lot more interesting.

Spectroscopy Top 10 Articles of the Month (September 2026)
The following articles are the most accessed digital object identifier (DOI) manuscripts for Spectroscopy and LCGC International during the month of September 2026. Nine articles are individually ranked here by DOI page views; the third-highest entry (186 views) was recorded against the bare journal-level DOI rather than an individual article and is therefore not attributable to a single manuscript.
