Polyelectrolyte Complex: Preparation and Biomedical Applications

Natural polyelectrolyte complexes (PECs) are getting more attention owing to their formation by the interaction of opposite charges with the help of electrostatic force. Polyelectrolyte complex reduces the toxic effects of the cross-linking agents. Polyelectrolyte complexes can be classified on various bases. Chitosan has been admired over other polymers in case of PECs formation due to the avoidance of organic solvents, chemical cross-linking agents and other toxic chemical solvents to reduce the toxicity and undesirable side effects. PECs formation due to the avoidance of organic solvents, chemical cross-linking agents so that it can reduce the toxicity and undesirable side effects The current report highlights properties, factors affecting it and various technologies. In the present report, we intend to discuss the applications of natural polyelectrolyte complexes such as biomedical, controlled delivery, medicine, and the area which can cause controlled release in different aspects. Patents related to these inventions are added along with their pivotal roles.
