“…DLEI does not require sample pretreatment or introduction into a vacuum chamber because of its ability to rapidly measure the mass spectra of multiple components in a sample [correlation between m/z (a dimensionless quantity obtained by dividing the mass of an ion by the unified atomic mass unit and then dividing by the charge number of the ion) and intensity information 17) ]. In MSI using DLEI, the area to be extracted and ionized is scanned across the sample surface.…”

Biological tissues are composed of a wide variety of chemical components, in which the amount and distribution of these components change dynamically according to health status. Mass spectrometry imaging (MSI) can be applied to biomedical research because of its ability to measure chemical components in a sample’s local area as a mass spectrum and visualize the chemical species distribution in a sample. This study reviewed the development of the tapping-mode scanning probe electrospray ionization (t-SPESI) technique to combine atomic force microscopy and mass spectrometry. t-SPESI uses a vibrating capillary probe to achieve rapid extraction, ionization, and MSI using picoliter solvents. Visualizing the distribution of disease-related components in the tissue was performed in the MSI of biological tissue. Multimodal imaging by t-SPESI was also demonstrated by implementing the optical detection of a probe vibration and the feedback control system into the t-SPESI.

JAPANIn the last decade, the field of mass spectrometry has changed radically, particularly mass spectrometry of biomolecules. The expansion in scope has led to growth in the number of terms and in the use of these terms by those not trained in mass spectrometry. As a result, compilations of terms and definitions, such as the forthcoming IUPAC compilation, should represent an extensive revision and expansion of their previous versions. Several arguments on terms concerning mass spectrometry have been raised by both domestic and international communities. This article summarizes the arguments and current status of the compilation to present the latest trends in mass spectrometry terminology. Qῡ̮ῲ῍ ̰̯ῌ QQ̱̲Ὼ´̳QQῥQQ῞̯QQῖῌ
