  • Surface science

    Surface science techniques deal with the property of surfaces and sub-surfaces up to several nanometers from the surface. This facility has expertise in:

    • X-ray photoelectron spectroscopy, which enables us to probe the surface chemical composition, chemical states and the composition distribution along the depth through depth profiling
    • Secondary ion mass spectrometry (SIMS)
    • Atomic force microscopy, which reveals the surface topography information and physical properties at sub-nanometer scale
  • Optical microscopy

    The optical microscopy team specializes in biological imaging and material sample characterization with expertise in:

    • Cell culturing, staining, and tissue processing
    • 2D, 3D and 4D imaging
    • Advanced live cell imaging
    • Image processing
    • Surface topography inspection, grain size and porosity analysis
    • Dynamic process imaging
    • Physical characterization
  • Physical characterization

    The physical characterization team specializes in physical property characterization, with a focus on X-ray diffraction, Raman spectroscopy, and electrical characterization. Our expertise includes:
