Abstract:: Polysarcosine (psar) is a non-ionic hydrophilic polypeptoid with numerous biologically relevant properties. Polysarcosine is poly (n-methylated glycine) and has been reported first by wesley and co-workers in the 1920s. Polysarcosine was first synthesized via ring-opening polymerization (rop) of sarcosine n-carboxyanhydride, using high-vacuum techniques. Overall, findings highlight the potential of poly(sarcosine) as an alternative corona-forming polymer to poly (ethylene glycol)-based analogues of (polymerization-induced self-assembly) pisa assemblies for use in various pharmaceutical and biomedical applications. Numerous studies suggested that such polypeptoids hold enormous potential for many biomedical applications, including protein delivery, colloidal stabilization, and nanomedicine.

The block copolymer poly (ε-caprolactone)-b-poly (N-isopropyl acrylamide) (PCL-b-PNIPAM) is synthesized via the combination of ring-opening polymerization (ROP) and reversible addition-fragmentation chain transfer (RAFT). PCL-b-PNIPAM can self-assemble into the micelles taking PCL as the cores and PNIPAM as the shells. Add α-CD into the micelles, because the inclusion complexation of α-CD to PCL chains and phenols is stronger than that to PCL, to regulate the hydrophilic and hydrophobic features of PCL chain. So PCL-b-PNIPAM block copolymers have potential application in drug delivery and gene transfection.
