Elemental Speciation Analysisin the 21st Century

Here are the top five articles that the editors of Spectroscopy published this week.

Creating uniform and repeatable monolayers is incredibly important for both scientific pursuits as well as the manufacturing of products in semiconductor, biotechnology, and. other industries. However, measuring monolayers and functionalized surfaces directly is. difficult, and many rely on a variety of characterization techniques that when used together can provide some degree of confidence. By combining non-contact atomic force microscopy (AFM) and IR spectroscopy, IR PiFM provides sensitive and accurate analysis of sub-monolayer of molecules without the concern of tip-sample cross contamination. Dr. Sung Park, Molecular Vista, joined Spectroscopy to provide insights on how IR PiFM can acquire IR signature of monolayer films due to its unique implementation.

Chinese scientists recently created a dual-response fluorescent probe to better understand the pathological mechanisms of depression disorder.

Metrohm considers NIR spectroscopy to be fast, easy to use, non-destructive, and chemical-free, and has developed a new addition to its platform for the analysis of liquid, solid, or a combination of samples in a short time.

Scientists from Nanjing Forestry University recently used a portable hyperspectral imager to help detect maturity stages in Camellia oleifera fruits.
