AI Summary

Researchers at Heinrich Heine University Düsseldorf demonstrated that complex molecular nanostructures can be selectively activated, disassembled in a controlled manner, and reassembled using ultrasound. The work, led by Dr. Bernd M. Schmidt and Professor Jan Meisner, was published in Nature Communications and represents a step toward intelligent molecular materials. The study focuses on supramolecular cages—three‑dimensional assemblies built from molecular building blocks—whose targeted assembly is known but whose selective disassembly has been difficult. The ability to manipulate these cages with ultrasound could support future applications such as molecular reaction chambers, sensors, and more precise drug‑delivery systems.
