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

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 led by Detlef Gunther examined using laser ablation with inductively coupled plasma time-of-flight mass spectrometry (LA-ICP-TOF-MS) in quantifying elements in biotissues of plants.

In a recent study out of China, Liyi Zhou and her fellow scientists created a nanoprodrug system to help treat liver cancer.

A recent study from the University of Shanghai for Science and Technology used surface-enhanced Raman spectroscopy (SERS) to improve analysis of biological fluids such as urine.
