Analogous to peptides, non-natural poly(N-substituted glycine) “peptoids” exhibit self-assembly properties and bioactivity that are encoded by the ordering of monomer residues into specific sequences along their polymer backbone. Peptoids differ from peptides in the shift of the sidechain attachment to the backbone amide-nitrogen atoms. They are resistant to protease degradation and have simplified intermolecular interactions.
This webinar highlights recent efforts in exploring solid-phase synthesized peptoids for applications beyond their conventional use in combinatorial drug discovery. The featured speaker will showcase a series of novel properties including the shortest peptoid motifs found to self-assemble into micelles and nanofibrils, “stealth” surface-grafted peptoid brushes that resist biofouling, as well as the modification of known sequences to retain antimicrobial activity for biomedical surface applications. Preliminary results also show that self-assembled peptoid nanosheets can influence protein expression of stem cells under culture. Selected peptoids have been synthesized with a Prelude® X peptide synthesizer.

Dr K. H. Aaron Lau leads his research group in bioinspired molecular interfaces at the University of Strathclyde. He is a senior lecturer (associate professor) in the department of pure and applied chemistry and a founding member of the university’s bionanotechnology initiative. He obtained his Bachelor of Science and Master of Science at Brown University, PhD at the Max Planck Institute for Polymer Research and postdoctoral training at Northwestern University.
His interest is in developing self-assemblies and synthetic surfaces that mimic the nanoscale organization and functionalities observed in natural molecular interfaces. This “biointerfacial” research is driven by both fundamental scientific inquiry and potential applications. The impact of Aaron’s research is in two main areas: i) sequence-specific “peptoids” as novel nanoassemblies, antibacterial surfaces and biomaterials, and ii) surface modification of synthetic materials, especially cellulose, using “polyphenol coatings” for enzyme biocatalysis and biomedical and environmental sensing applications.
His awards include the US NIH National Research Service Award (2011), RSC mobility fellowship (2014), Scottish Crucible (2015) and the Human Frontier Science Program (HFSP) Young Investigator award (2016).Message Presenter
