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.

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

Big Pharma companies like Bristol Meyers Squibb and Pfizer have been restructuring and laying off workers, moves that could be worrisome for analytical scientists.

A recent study used deep level transient spectroscopy to investigate the electrical response of defect filling and emission in monolayer metal-organic chemical vapor deposition (MOCVD)-grown materials deposited on complementary metal-oxide-semiconductor (CMOS)-compatible substrates.
