From: High-frequency terahertz waves disrupt Alzheimer’s β-amyloid fibril formation
Terahertz waves loosen the fibril conformation by transforming the β-sheet structure to contain more coil and bend regions. a Schematic of the Aβ1–42 simulation system in 0.15 M NaCl in water. b The THz spectrum of bulk water and Aβ1–42 fibrils in the range from 0 to 50 THz. c Changes in the secondary structure of the protein irradiated by a 34.88 THz wave. d Changes in the secondary structure of the protein irradiated by a 37.25 THz wave
