Time-of-Flight Secondary Ion Mass Spectrometry Imaging of Biodevices

Journal of the Mass Spectrometry Society of Japan, 2007
Time-of-flight secondary ion mass spectrometry (TOF-SIMS) imaging provides ten-nanometer-scale chemical images of biodevices. It is one of the most sensitive surface analysis methods and has recently been applied in life sciences. TOF-SIMS is useful for the evaluation of biodevice surfaces, because it provides ten-nanometer-scale mapping and chemical ...
