Research Objectives and Approach

  • Elemental mapping in cells and tissues

    • Development of sample preparation methods that retain the native distribution of the elements of interest
    • Microanalysis of biological samples applying EDS, EELS, and EFTEM
  • Development of a multiple labeling system for immuno-EM

    • Immunolabeling with markers that are distinguished based on their elemental composition
