Recently, layer-by-layer (LbL) assembly has emerged as a versatile, gentle and, simple method for immobilization of functional molecules in an easily controllable thin film morphology.1,2 In this short review, we introduce recent advances in functional systems fabricated by using the mild, yet adaptable LbL technique.
We present an article that discusses two applications in particular; first, using these layers as polyelectrolyte membranes to control permeability.
