Manufacturing new materials at the nanoscale level is a field that is rapidly expanding with widespread application in advanced science and MMT is effectively used for the technology. Nanoparticles (NP), the building blocks of nanotechnology, exhibit improved properties than the larger counterparts and can be prepared from a variety of metals, including silver, copper, gold, zinc, and others. Phytonanotechnology is gaining major attention as various clinical researches have focused on the excellent properties (physicochemical and biological) of nanoscale phytochemicals and its applications in biological systems. In recent developments, pomegranate (Punica granatum L.) has gained major attention due to the phenolic compounds like apigenin, caffeic acid, chlorogenic acid, cyanidin, ellagic acid, gallic acid, granatin A, granatin B, pelargonidin, punicalagin, punicalin and quercetin found in its peel. Pomegranate Peel Extract (PPE) that aid the synthesis of PPE mediated nanoparticles (PPE-MNPs) like PPE-MAuNPs, PPE-MAgNPs, PPE-MZnONPs, PPE-MCuNPs, PPE-MPtNPs and PPE-MFeNPs has yielded plethora of beneficial properties in both plants and humans. In the current review, we discuss in detail the recent advances in synthesis and characterization of various nanoparticles from PPE. Moreover, the multitude biological properties of PPE-MNPs make up the long list of clinical uses. In addition, we discuss the pharmacokinetics, current advantages, and limitations of PPE-MNPs which can further help in development of more efficient therapeutics. Despite some of the challenges, PPE-MNPs hold a lot of potential for drug delivery and are always a better choice. The convergence of science and engineering has created new hopes, in which phytomedicines will have more efficacy, bioavailability, and less toxicity.
