N2 - Elemental imaging of biological samples using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) provides spatially resolved information on element distribution in thin sections. By rastering with a laser across the sample, a two-dimensional image of the elemental distribution can be reconstructed that shows the intensities of the respective elements. Using overlapping laser shots the area ablated from single cells or thin sections (thickness 5 to 10 µm) can be reduced significantly so that the pixel size of the intensity measurement is significantly reduced. Having in mind that a laser shot ablates thin biological samples completely, we can make use of a new concept for calibration in the laser ablation method: the concept of total consumption. This calibration strategy allows production of simple matrix matched standards and provides an internal standardisation by ink jet technology, where a metal containing inks is printed on as thin layer on top of a biological sample. Different applications will be presented where our concepts have been applied. In the first example we used nanoparticle suspension of given particle numbers to quantify the uptake of metallic nanoparticles by biological cells. In the second example antibodies have been tagged by metals to measure protein expression in prostata cancer. In this approach application of house keeping proteins are investigated additionally to compensate variations in thickness and density of the biopsy samples. In the third application different nephrotoxic behaviour of Pt containing drugs have been investigated to study the local enrichement in kidney samples of mice treated with these three different compounds. Here the internal standard is required to allow intercomparisons between different individual mouse tissues. At the end of the lecture future trends will be discussed for elemental microscopy.

T1 - Novel strategies for standardization and calibration in Laser Ablation ICP-MS N2 - Elemental imaging of biological samples (bio-imaging) using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) provides spatially resolved information on element distribution (qualitative and quantitative) in thin sections of biological samples. By rastering with a laser across the sample, a two-dimensional image of the elemental distribution can be reconstructed that shows the relative intensities of the respective elements. However the method is hampered by a lack of internal standards and quantification concepts, which will be discussed in this lecture in more detail. In liquid analysis the internal standard is used for drift correction and calibration and thus it is required that the standard should have similar physical and chemical properties similar to the analyte element during the pneumatic nebulization process, the transport, ionization and transmission into the ICP-MS. In laser ablation it should correct additionally for differences in the ablation process by laser instabilities or changes of sample properties to compensate variations or drift effects during the LA process.

For this purpose, we are using different sample introduction systems for ICP-MS for detection, imaging and quantification of metals at cellular levels. By use of laser ablation, we have studied the up-take by and distribution of nanoparticles in single cells. Recently we have developed staining techniques to measure protein and DNA content of cells and identifying the cell status by immunoassays using metal-tagging of antibodies. New research based on cell arrays will be shortly discussed. Using pneumatic nebulization and microdroplet generation, we have also studied the up-take of nanoparticles and toxic metals as well as essential elements in single cells using different ICP-MS mass spectrometric concepts (sector field instrument, triple-quad instrument, time of flight (CyTOF) instrument). The different ICP-MS based methods will be compared concerning their analytical figures of merit and their strengths and weaknesses will be evaluated.
