ATP-Regulated Formation of Transient Peptide Amphiphiles Superstructures.

Summary: Imagine microscopic building blocks that can organize themselves just like living cells do. Scientists have developed synthetic "nanofibers" that mimic biological systems. When a specific biological fuel called ATP is added, these fibers clump together into thick bundles, effectively turning them "off" and stopping their chemical activity. However, when an enzyme eats away the fuel, the bundles fall apart, the fibers separate, and they turn back "on." This discovery allows researchers to use fuel levels to precisely control when and how these tiny structures perform chemical reactions, acting like a temporary switch for nanotechnology.
