WebA molecular model is proposed in which zones of different rigidity and thickness bring about phase boundary defects that ultimately lead to permeability induction and peptide crossing through bacterial membranes. The increasing resistance of bacteria to conventional antibiotics makes the development of new modes of treatment essential. WebSeveral strategies, such as phase cycling following Malcolm Levitt (MLEV) schemes or using composite pulses, are employed in order to make T 2 preparations more robust to field inhomogeneities (32, 33).
