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
Weslay 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.
