摘要:
Langmuir-Blodgett lipid films and plasma membranes of glioma cells were analyzed using time-of-flight secondary ion mass spectrometry (TOF-SIMS). Bi-3(+) primary ion beam was determined to be the most efficient in various experimental setups. TOF-SIMS was shown to be applicable for a quantitative analysis of model lipid structures as well as plasma membranes of glioma cells U87MG in vitro. A combination of atomic-force microscopy and scanning electron microscopy yielded the depth resolution of similar to 10-20 nm for cell surface scanning by primary ion beam.
