Background: In this review, preparation method with various applications of
polyelectrolyte complex is studied with the aim to assess various attributes to different fields.
Polyelectrolyte complex is formed when contrarily charged polyelectrolytes are mixed together.
Description: The adoption of PEC is benefitting the pharmaceutical and biomedical field with vast
applications and reliability. They provide better encapsulation efficiency; control the release rate of
drug, immobilization of microbes, bio-sensing, wound healing and used as tissue scaffolds. PECs are
used over single electrolyte as they are not been able to show idiosyncratic appositeness in the
Conclusion: The scope of this review accentuate on the detailed study of applications of
polyelectrolyte complexes and their efficacy so that they may gain more interest progressively. To
provide several applications based on polyelectrolyte complex is the eventual objective of this review.
