Polyelectrolyte complexes are getting more attention owing to their formation by the interaction of opposite
charges with the help of electrostatic force. Polyelectrolyte complexation reduces the toxic effects of the cross-linking
agents. Polyelectrolyte complexescan be classified on various bases. The current report highlights properties, factors affecting
it and various technologies. In the present report we intend to discuss the applications of polyelectrolyte complexes
such as biomedical, controlled delivery, medicine, and area which can cause controlled release in different aspects. Patents
related to these inventions are added along with their pivotal roles.
Keywords: Biomedical application, drug delivery, polyelectrolyte complex.
