Modifications induced in lipid multilayers by241Am α-particles

  • Published:
Lettere al Nuovo Cimento (1971-1985)

Summary

It has been observed by differential scanning calorimetry that241Am α-particles induce modifications in phosphatidylcholine multilayers in the presence of water excess. Actually, below main transition point the mentioned defects seem to be randomly distributed within the lipid matrix; while above main transition there is some tendency to cluster. Moreover, increasing the irradiation time, the initial temperature of the main transition decreases, while a tail towards higher temperature appears. Such broadening of the lipid main transition seems to indicate the presence in the bilayers of different components than those created by γ-radiation.
