Bioimaging mass spectrometric techniques allow direct mapping of metal and biomolecule distributions with high spatial resolution in biological tissue. In this study laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) was used for imaging of transition metals (Fe, Cu, Zn, Mn, and Ti), alkali and alkaline-earth metals (Na, K, Mg, and Ca,(More)
Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) has been established as a powerful and sensitive surface analytical technique for the determination of concentration and distribution of trace metals within biological systems at micrometer spatial resolution. LA-ICP-MS allows easy quantification procedures if suitable standard(More)
Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) has been developed as a powerful MS imaging (MSI) tool for the direct investigation of element distributions in biological tissues. Here, this technique was adapted for the analysis of native mouse spinal cord cryosections of 3.1 mm × 1.7 mm by implementing a new conventional ablation(More)
