Photoactive g-C3 N4 Nanosheets for Light-Induced Suppression of Alzheimer's β-Amyloid Aggregation and Toxicity.

Graphitic carbon nitride (g-C3 N4 ) has a suppressive capability toward Alzheimer's Aβ aggregation under light-illumination. Photoinduced electrons of g-C3 N4 generate reactive oxygen resulting in photooxidation of amyloid peptides that blocks Aβ aggregation. Fe doping of g-C3 N4 frameworks results in enhanced optical properties and even stronger inhibition of Aβ aggregation.
