Amyloid protein misfolds, abnormally aggregates and accumulates into amyloid deposits which endanger tissue functions and are closely related to the pathogenesis of many diseases including Type 2 Diabetes Mellitus (T2DM). There are on-going efforts to find new methods or effective reagents to disassemble and eliminate the existing amyloid aggregates. Herein, we showed that a gold nanoparticle-modified quasi-2D nanomaterial, Au/g-C3N4, could efficiently degrade preformed amyloid aggregates. Furthermore, the scavenger experiment revealed this photodegradation effect was depended on the induced oxygen radicals, particularly hydroxyl radical. The new finding in this work could demonstrate that a gold nanoparticle-modified quasi-2D nanomaterial would have potential applications in the strategy design of the treatment of amyloid related diseases in future.
