Imaging of metal-based nanoparticles in tissue and cell samples by laser ablation inductively coupled plasma mass spectrometry

  • Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) is nowadays a versatile and powerful analytical method for direct solid sample analysis. The applicability has been demonstrated for a wide variety of samples covering hard and soft materials. In an imaging mode the technique provides quantitative information on the elemental distribution within a sample. LA-ICP-MS imaging is of particular interest in biomedical research as the distribution of an element gives valuable insight on uptake and distribution of essential and toxic trace elements, administered contrast agents as well es nanoparticles. LA-ICP-MS is therefore a powerful complement to other imaging techniques. Recent instrumental improvements, especially in sample chamber design, have contributed to better sensitivity and spatial resolution enabling subcellular imaging.

LA-ICP-MS is therefore a powerful complement to other imaging techniques. Recent instrumental improvements, especially in sample chamber design, have contributed to better sensitivity and spatial resolution enabling subcellular imaging. The book chapter provides a comprehensive overview about spatially resolved localisation and quantification of various nanoparticles in cells and tissue thin sections by LA-ICP-MS. Furthermore, different sample preparation strategies and internal standardisation and calibration approaches for bioimaging by LA-ICP-MS are summarized and discussed. Metal-containing nanomaterials are used in numerous fields ranging from industrial applications to nanomedicine. Several studies have demonstrated that the physicochemical properties of nanoparticles have an impact on their pharmacokinetics, transfer and clearance. The high sensitivity and multielement capability of LA-ICP-MS enables the elucidation of interactions between tissue components and nanomaterials used as imaging probes or drug carriers. Potential toxic effects are investigated as well. Thus, LA imaging significantly supports the clinical translation of safe and efficient nanoparticles for diagnostic and therapeutic purposes.zeige mehrzeige weniger
