Abstract

The conducting polymers are conjugated carbon chains with alternating single and double bonds with highly delocalized, polarized, and electron-dense π bonds that are responsible for their electrical behaviour. Amongst various conducting polymers, polypyrrole (PPy) is a heterocyclic oxidized pyrrole which is one of the most demanding conducting polymers that has gained significant attention in the field of biomedical applications due to their unique electrical and physicochemical properties. This mini-review provides an overview of the synthesis and recent applications of PPy for various biomedical applications such as tissue engineering, bio-sensing, drug delivery, and implants.
