제목 Near-Infrared Light-Responsive Alginate Hydrogels Based on Diselenide-Containing Cross-Linkage for on Demand Degradation and Drug Release
초록 A biodegradable, near-infrared (NIR) - responsive hydrogel is one of the most promising strategies as a remotely triggered drug carrier. A novel NIR-responsive hydrogels based on alginate structures were prepared for controllable drug release. The hydrogels were formed rapidly by reacting norbornene-functionalized alginates and tetrazine cross-linkers containing diselenide bonds via inverse electron demand Diels-Alder click chemistry. NIR sensitive indocyanine green (ICG) and a drug, doxorubicin (DOX) were incorporated in the hydrogel matrix during gelation. The hydrogels showed a suppressed release profile under physiological conditions, while NIR light triggered a rapid release of DOX. Under NIR-light irradiation, ICG generated reactive oxygen species which could decompose diselenide bonds in the hydrogel matrix, inducing the gel-sol transition and release of entrapped DOX.
