Layer-by-layer (LbL) self-assembly membranes are multilayered nanoarchitectures obtained by depositing oppositely charged polyelectrolytes or molecules presenting mutually interacting binding sites (Table 1) (Borges and Mano 2014). The LbL method can not only be applied to polymers but also on the combinations of polymers with particles.
