will speak on
“Peptide-Based Nanotechnology”
Abstract:
We are interested in how functionality emerges from sequence in ensembles of very short peptides, and subsequently how these functions can be incorporated into functional materials. Instead of using sequences known in biological systems, we use unbiased computational and experimental approaches to search and map the peptide sequence space, which has provided new families of functional short peptides. The talk will focus on our latest results in three areas. First, we will demonstrate how to program molecular order and disorder in tripeptides, and how the conformations adopted by these peptides can be exploited to regulate assembly properties, and give rise to tunable emission in the visible range. Second, we will demonstrate how dynamic exchange of peptide sequences can form adaptive libraries that provide insights into peptide sequences that can complex ligands.Finally, we discuss peptide-based melanin mimics with tunable chromophoric properties that are achieved through oxidative incorporation of amino acids.
