摘要：
Alternate adsorption is a well-known method for developing the novel ultrathin films of biodegradable polyion complexes. This study revealed variations in the effect of chitosan and poly(γ-glutamic acid) [γ-PGA] molecular weight on the complex formation process. High molecular weight γ-PGA showed a high adsorption frequency. In contrast, no molecular weight effect was observed in the case of chitosan. Addition of certain organic solvents in the chitosan and γ-PGA aqueous solution also influenced ultrathin film polyion complex formation.
