In his SciX interview, Marc Porter discusses what happens to hydrogen when thiols bind to gold, how close analytical chemists can get to detecting a single molecule in a liter, and his new PFAS-focused startup.

From quarry fingerprints to bat-driven salt damage and hidden wall paintings, portable X-ray fluorescence, Raman spectroscopy, and isotope analysis are revealing how Angkor Wat was built and what threatens it today.

Yukihiro Ozaki of Kwansei Gakuin University received the Raman Lifetime Award at ICORS 2026 in Istanbul for outstanding lifetime contributions to Raman spectroscopy.

At SciX, Alessandro De Giacomo explained how airborne LIBS can produce quantitative results. Instead of relying on reference measurements, the method draws calibration directly from the measured signal, which sidesteps the drone’s positioning and motion problems.

At SciX, Jürgen Popp explains how miniaturized optical spectroscopy could add molecular data to wearable health tracking, which could enable earlier disease detection and a shift toward prevention.

At SciX, Jay Kitt describes the experiment he ran on his own that launched his cytochrome c research, and explains why putting a number on peptide–lipid interactions matters.

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.

Jürgen Popp explains how head and neck surgeons in Jena use a Raman probe to locate tumor borders, why the technique could replace frozen section biopsies, and why optical tools must adapt to clinical workflows rather than the other way around.
