Modifying amino acid and peptide proteins and biodegrades enables 3D glass printing

"modified ends of amino acids to change assembly and stop breaking up. After melting, rapidly supercooled to solidify into glass which stayed solid at room temperature... biodegrade glass not appropriate for humid or wet... Organic chemical bonds tend to be weaker than inorganic bonds, so less rigid than standard glass, but this property could be beneficial in flexible, miniature devices, such as the lenses of a microscope"
