Measurement of geologic nitrogen using mass spectrometry, colorimetry, and a newly adapted fluorometry technique [PDF]
Solid Earth, 2017 Long viewed as a mostly noble, atmospheric species, recent work demonstrates that nitrogen in fact cycles throughout the Earth system, including the atmosphere, biosphere, oceans, and solid Earth.

Robustness of high‐throughput prediction of leaf ecophysiological traits using near infrared spectroscopy and poro‐fluorometry [PDF]
The Plant Phenome Journal, Volume 9, Issue 1, December 2026.Abstract Water scarcity is a major threat to crop production and quality. Improving drought tolerance through variety selection requires a deeper understanding of plant ecophysiological responses, but large‐scale phenotyping remains a bottleneck. This study assessed the potential of high‐throughput tools (spectroscopy and poro‐fluorometry) to predict ...

High-Sensitivity Fluorometry to Resolve Ion Channel Conformational Dynamics [PDF]
Cell Reports, 2018 Summary: Fluorescent labels offer the capability to follow conformational dynamics of membrane proteins, but signal detection in such recordings is inherently difficult to achieve in a cell membrane and lacks sufficient time resolution to follow ...

Atmospheric nitrogen deposition and canopy retention influences on photosynthetic performance at two high nitrogen deposition Swiss forests [PDF]
Tellus: Series B, Chemical and Physical Meteorology, 2012 Portable chlorophyll fluorometry measurements, providing plant photosynthetic efficiency (PE) data, were carried out at two contrasting Swiss forests experiencing high nitrogen (N) deposition. Fluorometry data were obtained in conjunction with controlled
