摘要: PEGylation in polymeric nanomedicine has gained substantial predominance biomedical applications due to its resistance protein absorption, which is critically important for a therapeutic delivery system blood circulation. The shielding layer of PEGylation, however, creates significant steric hindrance that negatively impacts cellular uptake and intracellular distribution at the target site. This unexpected effect compromises biological efficacy encapsulated payload. To address this issue, one key strategies tether disulfide bond PEG constructing disulfide-bridged cleavable PEGylation. reversible can be cleaved enable selective detachment. article provides an overview on strategy, method progress nanosystem with bond.
