When two oppositely charged biopolymers are mixed together, they may form either segregative or associative phase system. The former behavior refers to the repulsive force existed between two polyelectrolytes; whereas, the latter one is happened when the attractive interactions are existed. Furthermore, the formation of nanoparticles and microparticles are dependent on the strength of attractive forces. Since the nanoparticles are the result of weak electrostatic interactions, their ordered structure as well as good stability is comparatively still worse than that of microparticle
