Colorimetric tracking of protein structural evolution based on the distance-dependent light scattering of embedded gold nanoparticles

Chem Commun (Camb). 2012 Feb 25;48(17):2286-8. doi: 10.1039/c2cc17174k. Epub 2012 Jan 4.

Abstract

In this communication, we describe a new, simplified colorimetric method for in situ tracking of structural evolution of Cu/Zn-superoxide dismutase (SOD1) aggregates, based on changes in plasmonic coupling between gold nanoparticles (GNPs) embedded along the structural backbone of the SOD1 aggregates.
