Abstract:

It was the overall aim of this research program to develop a new class of transient functional nanostructures based on self-assembling peptides. These materials mimic the ability of living systems to rapidly adapt and respond to new situations by changing their structure and optical properties. While they are conceptually inspired by biology, the systems that were developed are much simpler in composition, and combine biological and synthetic components, giving rise to structures and functions, including adaptive fluorescence emission, that are not accessible using biological or synthetic approaches alone. The main outcomes were development of dynamic peptide libraries for discovery of self-assembling peptides Nature Nanotechnology, 2016, discovery of customizable polymeric peptide pigments with sequence tunable properties Science, 2017 and the demonstration of amino acid encoded transient assemblies, showing transient electroconductance Nature Chemistry, 2018.
