Methods of Manufacturing and Using Beta-Peptide Lyotropic Liquid Crystals
WARF: P06005US

Inventors: Samuel Gellman, Nicholas Abbott, William Pomerantz

The Wisconsin Alumni Research Foundation (WARF) is seeking commercial partners interested in developing liquid crystals based on beta-peptide scaffolds.
Overview
Liquid crystals have been widely explored for applications such as display and sensing technologies. Lyotropic liquid crystals, which become more ordered as they become more concentrated within a solvent, are particularly useful for detecting the presence of biological targets, including proteins, viruses and microbes. Some alpha-peptides have been used to form lyotropic liquid crystals, but these peptides must be quite long, which limits their use.
The Invention
UW-Madison researchers have developed liquid crystals based on relatively short beta-peptide scaffolds that can be tailored to have unique properties for use in biological assays. Beta-peptides differ from conventional peptides in that certain beta-peptides form stable helices at short, oligomeric lengths, giving rise to robust, asymmetric structures. These helical beta-peptides can self-assemble to form lyotropic liquid crystals in aqueous environments.

To give the liquid crystals more desirable properties, a variety of functional groups can be added to the beta-peptides. The liquid crystals can then be used, for example, to detect an analyte, such as a protein, in a biological sample.
Applications
  • Detection of proteins, cells or viruses
Key Benefits
  • Modular synthesis of beta-peptides allows control over the location of functionalized side chains, including ionic groups that confer aqueous solubility and aromatic groups that influence liquid crystal properties.
  • Oligomers of beta-amino acids may incorporate chemical groups and/or small molecules to further functionalize the resulting liquid crystal.
  • Beta-peptides can be tailored to have specific viscosity and birefringence, important qualities for liquid crystals.
  • Beta-peptides are resistant to proteolysis and generally non-toxic to cells, making them useful for biological applications, such as biomolecular sensing of proteins, cells or viruses in biological samples.
