摘要: Abstract : B. thuringiensis spores must have similar properties to anthracis be a good simulant in counter-proliferation studies. In particular, they behave way when exposed high temperatures for short periods of time as would caused by an explosion. This research project compares surface elasticities four different spore sample types, spores, heat inactivated and spores. Heat were temperature just enough that no observed germinate. Elasticity values the surfaces determined measuring reflection transmission acoustic waves between atomic force microscope (AFM) tip, assuming Hertz contact model. had higher more variable elasticity then inactivation decrease. Calculated average 3.73 GPa anthracis, 2.73 4.67 thuringiensis, 3.57 thuringiensis.
