Surface Sensitive Photothermal AFM-IR Unlocks New Dimensions in Precision Analysis for Top Layer of Sample

Two researchers hailing from Wageningen University and the Norwegian University of Life Sciences collaborated on a new method that improves on existing multilinear predictive modeling methods.

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.

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

A recent study from Shenzhen University used a novel biosensor based on Fano resonance to improve the detection of cancer.

Scientists from Duke University in Durham, North Carolina recently tested a surface-enhanced Raman scattering (SERS) spectroscopy system for detecting the SARS-CoV-2 virus.
