Overview

Neutron backscattering spectroscopy provides a nondestructive and label-free method to study the dynamics of proteins and their hydration water. This article discusses two studies focusing on amyloid proteins, specifically the time-resolved dynamics of lysozyme during aggregation and the hydration water dynamics of tau during fiber formation.
