Abstract
Background: Polymersomes (PS), self-assembled nanostructures formed by amphiphilic block copolymers, have garnered significant attention in recent years due to their unique properties and versatile applications in the fields of drug delivery and biomedicine. They are being prepared for a wide range of complex medicinal compounds, including nucleic acids, proteins, and enzymes. Polymersomes have lately been used as vehicles for delivering varied therapeutic substances and regulating ROS (reactive oxygen species). Due to their immunogenic features, polymersomes could play a critical role in enhancing subunit vaccine and drug delivery against COVID-19 infection.
Objective: The prime purpose of this manuscript is to furnish an extensive overview of polymersomes, highlighting their recent advances, fabrication methods, characterization techniques, and pharmaceutical applications.
Methods: The article has been amassed using several online and offline manuscripts from reputed journals, books, and other resources. Besides this, various user-friendly interfaces, like Pubmed, Google Scholar, etc, have been utilized to gather the latest data about polymersomes. This domain encompasses recent advancements in the realm of innovations about the delivery of drugs through polymeric vesicles. This field involves innovations or developments in nanocarrier systems as they are efficaciously employed to deliver the desired moiety to the targeted site.
Results: PS have been discovered to exhibit remarkable promise in addressing various challenges associated with inadequate bioavailability, targeted drug delivery, dosing frequency, and diminished toxic effects. Over the past decade, such nanovesicles have been effectively employed as a complementary approach to address the issues arising from poorly soluble medications. However, this domain still requires further focus on novel breakthroughs.
Conclusion: Polymersomes demonstrate unparalleled potential as innovative carriers, exhibiting remarkable versatility and exceptional biocompatibility. This concise review underscores their extraordinary prospects in diverse fields, accentuating their distinctive attributes and opening new avenues for groundbreaking applications.
Keywords: Polymersomes, bioavailability, solubility, drug delivery, polymers, nanocarrier.
