title: Photolytic control of peptide self-assembly.
abstract: Herein, we present a methodology that allows for the temporal control of fibrillization of amyloidogenic peptides. This general approach implements a photolabile linker that connects the amyloidogenic peptide to a fibril-inhibitory unit, in this case, a pentamer of amino acids modified with the solubilizing N,N-dimethylethylenediamine (DMDA) units. Upon photolysis, the linker can be dissociated to afford the intact and native amyloidogenic peptide. This methodology should be of value in a variety of studies where spatial and temporal control of supramolecular association processes is desired.
