Fig. 3

The figure illustrates the structure and function of a disulfide-containing poly(ester amide) (SS-PEA) polymer designed for responsive drug delivery and cell culture applications. The polymer backbone contains disulfide bonds, enabling degradation under reductive intracellular conditions, while ester and amide bonds allow for degradation.
