Chemists Make Beds With Soft Landings: Researchers Create Stable, Highly Pure Helical Peptide Arrays
Bedsprings aren't often found in biology. Now, chemists have secured a layer of tiny protein coils onto a thin surface, much like miniature bedsprings in a frame. This thin film made of stable and very pure helices can help researchers develop molecular electronics or solar cells, or to divine the biology of proteins. The physical chemists pulled off this design trick using a "soft-landing" technique with a specially designed mass-selected ion deposition instrument.
