The multilayers can be assembled by a simple aqueous process involving the alternate adsorption of polycations and polyanions through electrostatic interactions [29].
Furthermore, the condensing agent must also possess the ability to protect ON from enzymatic degradation, be compatible with the nonviral delivery system, and resist displacement of the polycation from the ON due to a biologically relevant protein (albumin, fibrinogen, serum, etc) until it has reached its target.

used the technique of layer by layer self-assembly for producing free standing nanomembrane by using alginate with chitosan as this alginate is polyanion react with the amino group of chitosan enables it to ionize to a polycation in water, which shows a natural attraction to alginate because the carboxyl group of alginate turns it into a polyanion in water simultaneously.
