artificial molecular pumps

Artificial molecular pumps are engineered systems that move molecules or ions selectively and directionally across a barrier, mimicking natural processes like cellular transport. They use energy—often from light, chemical reactions, or electrical inputs—to change their structure, creating a driving force that pulls molecules in one direction. These tiny devices can control the flow of chemicals at the molecular level, which has potential applications in nanotechnology, drug delivery, and creating sophisticated materials. Think of them as nanoscale machines that actively manage the movement of molecules, enhancing our ability to manipulate matter with precision at the smallest scales.
