A group of materials scientists from Tel Aviv University and Ben Gurion University of the Negev, together with a colleague from the California Institute of Technology, discovered a surprising property of the short aromatic tripeptide YYY.

By mixing this peptide with water, they obtained self-assembling and self-healing glass. This discovery, published in the journal Nature Communications, happened by chance when the researchers were studying the properties of other proteins.

As part of the experiments, the scientists worked with a dipeptide consisting of two phenylalanine residues. When this molecule was mixed with water and allowed to evaporate at room temperature, a new type of supramolecular amorphous glass was formed. The most surprising thing was that usually the self-assembly of peptides leads to crystalline structures that are not transparent and not suitable for making glass.

After studying the properties of the new material, scientists discovered that it is not only self-healing, but also has high strength and transparency, comparable to traditional glass. The new material also proved to be adhesive and able to create hydrophilic surfaces. It can be used for the production of glass panels and coatings, as well as for the production of high-magnification optical lenses.

The research team suggests that further testing could lead to a wide range of applications for the new type of glass. An important advantage of the new material is that its production requires significantly less energy compared to traditional glass manufacturing methods.
