Trehalose is a well-known antiamyloidogenic molecule that inhibits protein aggregation under the intracellular/extracellular condition, and recent work shows that the nanoparticle form of trehalose can further enhance this performance. Here we have designed a trehalose-functionalized Au nanoparticle that can inhibit the aggregation of a polyglutamine-containing mutant protein inside the neuronal cell. Designed nanoparticles have a 20-30 nm Au core with about 350 50 trehalose molecules per particle on the surface on average. They enter the cell, inhibit mutant protein aggregation, and enhance the cell survival against toxic protein aggregates. This work extends the application potential of trehalose for the understanding and treatment of different diseases involving protein aggregation.
