Molecular machines consist of discrete molecular components assembled to produce mechanical movements in response to specific stimuli, acting as motors, switches, or shuttles at the nanoscale. Building upon the foundational work awarded the 2016 Nobel Prize in Chemistry, 2025 has marked a shift from theoretical synthesis to practical, high-impact applications in data storage, medicine, and materials science.

Ultra-High Density Data Storage A significant breakthrough in 2025 involves the engineering of single-molecule magnets (SMMs) capable of retaining magnetic memory at 100 Kelvin (-173°C). Previous SMMs required much colder temperatures (around 4 Kelvin), making them impractical. Developed by researchers at the University of Manchester and ANU, these dysprosium-based mole ...
