Researchers developed spherical and hollow gold nanoparticle-based SERS platforms that enable label-free molecular imaging of chemotherapy drug effects and drug release within cancer cells, offering a theranostic tool with potential applications in early cancer diagnostics.

In the second episode of “Spectroscopy Around the Globe,” host Will Wetzel takes viewers on a journey to England to explore how spectroscopy is being used to uncover the secrets of Stonehenge.

A study using fiber laser induced breakdown spectroscopy (FL-LIBS) to evaluate how pulse width and repetition rate affect the quantitative analysis of elements in aluminum alloys, reporting improved detection sensitivity and limit of detection at high repetition rate.

Environmental analysis is a growing area of study, and single-particle inductively coupled plasma–mass spectrometry (spICP-MS) is one of the techniques contributing to this growth.

What are some of the limitations of elemental selective techniques?

The following articles are the most accessed digital object identifier (DOI) manuscripts for Spectroscopy and LCGC International during the month of July 2026. Nine articles are ranked here by DOI page views; a tenth entry in the July report (135 views) was recorded against the bare journal-level DOI rather than an individual article and is therefore not attributable to a single manuscript.

How can inductively coupled plasma–mass spectrometry (ICP-MS) detect particles that were missed in initial analyses?

An upcoming poster presentation set to take place at the American Chemical Society (ACS) Fall 2026 Meeting will explore how spectroscopy is being used to distinguish different roasted coffee types.

Can spectroscopy make real-time monitoring in nuclear and radioisotope facilities faster and safer?

Welcome to “Analytically Speaking,” the podcast from LCGC International and Spectroscopy. Here in Episode #47, podcast host Dr. Jerry Workman speaks with Dr. Thomas Mayerhöfer from the Leibniz Institute of Photonic Technology (Leibniz IPHT) in Jena, Germany, and Friedrich Schiller University Jena, about “the other half” of the Beer–Lambert law: dispersion theory, the concentration law of the refractive index, and refractive-index and complex-valued chemometrics. Dr. Mayerhöfer, who first joined the podcast for Episode #29 on the history and theory of infrared spectroscopy, returns to explain how Beer’s law falls out of dispersion theory as a limiting case, why the refractive index obeys a concentration law of its own that was mainstream physical chemistry before about 1920 (and helped confirm the Kekulé structure of benzene), and how new refractive-index and complex-valued chemometric methods — in combination with PLS — can outperform conventional absorbance-based calibration by up to an order of magnitude.

Top articles published this week include a preview of an upcoming presentation at the American Chemical Society (ACS) 2026 Fall Meeting in Chicago, Illinois.

Laser-induced breakdown spectroscopy (LIBS) has moved from the laboratory to the field, offering rapid, in situ elemental analysis of minerals, rocks, soils, and meteorites with minimal sample preparation. This practical tutorial covers LIBS instrumentation, field sampling best practices, quantification methods, common pitfalls, and emerging applications in geoscience.

For 170 years, spectroscopists have built quantitative analysis on only one number pulled from every spectrum they ever recorded, discarding its inseparable twin. New dispersion-theory and complex-valued chemometric methods recover that missing half, the refractive index, and in favorable systems cut calibration error by as much as an order of magnitude.
