Аннотация
Langmuir–Blodgett lipid films and plasma membranes of glioma cells were analyzed using timeof-flight secondary ion mass spectrometry (TOF-SIMS). Bi3+ primary ion beam was determined to be 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 ~10–20 nm for cell surface scanning by primary ion beam.
