Cross-linking a priori brittle bovine serum albumin (BSA)with dynamic vinylogous urethane (VU) linkages producesrobust plastics with tensile strengths of up to 35 MPa. Simultaneously,thermal denaturation at 80 °C restructures BSA fromα-helices into more hydrophobic β-sheet-rich domains,reducing water absorption and thereby stabilizing the otherwise hydrolyzable VU cross-links. The resulting protein networks are chemicallyrecyclable in acidic water, allowing the recovery of both BSA and cross-linkers.

Perfluorocarbons possess excellentoxygen dissolution and transport capacities and have been widely employedto construct oxygen-enriched microenvironments. In addition, the heavy-atomeffect enhances intersystem crossing by promoting spin-orbit coupling,thereby increasing singlet oxygen generation. Herein, we synthesizeda series of amphiphilic bottlebrush polymers (BBPs) covalently graftedwith porphyrin photosensitizers, featuring tunable fluorine-containingside chains and iodine functionalization. Distinct from conventionalpolymeric PDT systems that primarily serve as photosensitizer carriers,the BBP architecture provides a confined multifunctional microenvironmentthat simultaneously regulates photosensitizer aggregation, oxygenavailability, and intersystem crossing. The strong steric repulsionbetween neighboring side chains prevents undesired photosensitizeraggregation and preserves their photoactivity, while the fluorine-richdomains and iodine substituents cooperatively promote singlet oxygengeneration through oxygen enrichment and external heavy-atom effects,respectively. Consequently, polymer vesicles assembled from thesefluorinated and iodinated BBPs exhibit significantly enhanced PDTefficacy.
