C NMR, MALDI-ToF MS, and size-exclusion chromatography (SEC). Intrinsic viscosities ([η]) of the s-PSar and s-PSar-b-PCL were estimated using SEC-MALS-VISC-DRI. Dynamic light scattering and transmission electron microscopy analysis showed that the s-PSar-b-PCL diblock copolymers self-assembled into spherical aggregates with average hydrodynamic diameters of 56-169 nm in aqueous solution. MTT assays (cell viability test) certified the biosafety (relative cell viability >80%) of the copolymers and their self-assembled nanostructures. Taken together, we (i) synthesized the novel s-PSar-b-PCL diblock copolymers, (ii) investigated the solution properties of the s-PSar-b-PCLs and s-PSars, and (iii) demonstrated the biocompatibility of s-PSar-b-PCLs.
