Improvement of biological time-of-flight-secondary ion mass spectrometry imaging with a bismuth cluster ion source.

TL;DR: A new liquid metal ion gun filled with bismuth has been fitted to a time-of-flight—secondary ion mass spectrometer (TOF-SIMS) and the results show a great improvement of the imaging capabilities in terms of accessible mass range and useful lateral resolution.
Journal ArticleDOI

Tissue Molecular Ion Imaging by Gold Cluster Ion Bombardment

TL;DR: The use of gold cluster focused ion beams produced by a liquid metal ion gun in a TOF-SIMS mass spectrometer is shown to dramatically enhance secondary ion emission of phospholipids and peptides.
Journal ArticleDOI

Diversity Among Microbial Cyclic Lipopeptides: Iturins and Surfactins. Activity-Structure Relationships to Design New Bioactive Agents

TL;DR: Improved physical techniques such as 2D-NMR and mass spectrometry allowed to describe efficiently and rapidly the composition of cyclic lipopeptides even in mixtures containing several variants, and the role of residues was identified in the context of hydrophobic and electrostatic interactions that play a leader role.
Journal ArticleDOI

Biological tissue imaging with time-of-flight secondary ion mass spectrometry and cluster ion sources

TL;DR: Time-of-flight secondary ion mass spectrometry (TOF-SIMS) using liquid metal ion guns (LMIGs) is now sensitive enough to produce molecular-ion images directly from biological tissue samples, fully compatible with subsequent and complementary analyses like fluorescence microscopy, histochemical staining, or even matrix-assisted laser desorption/ionisation imaging.
