Mass spectrometry imaging (MSI) has gone through a significant change over the last 3
years, the time span of this review. The predominant mass spectrometric method in …

Bacteria, either indigenous or added, are immobilized in solid foods where they grow as
colonies. Since the 80's, relatively few research groups have explored the implications of …

Microbial diversity studies using small subunit (SSU) rRNA gene sequences continue to
advance our understanding of biological and ecological systems. Although a good predictor …

Chemical signaling between cells is an effective way to coordinate behavior within a
community. Although cell-to-cell signaling has mostly been studied in single species, it is …

For decades, researchers have lacked the ability to rapidly correlate microbial identity with
bacterial metabolism. Since specialized metabolites are critical to bacterial function and …

Nowadays, matrix-assisted laser desorption/ionization time of flight mass spectrometry
(MALDI-TOF MS) is routinely implemented as the reference method for the swift and …

Aquatic environments are the recipients of many sources of environmental stress that trigger
both local and global changes. To evaluate the associated risks to organisms and …

Recently, a major increase in mass spectrometer installations has occurred in routine
clinical microbiology laboratories worldwide. At present, there are hundreds of various …

A sensitive, simple and reproducible protocol for nanoparticle-assisted laser
desorption/ionization mass spectrometry imaging technique is described. The use of …

In this work, we show the advantages of label-free, tridimensional mass spectrometry
imaging using dual beam analysis (25 keV Bi3+) and depth profiling (20 keV with a …
