molekyylikoneen

Molekyylikoneen is a Finnish term that translates to "molecular machine" in English. It refers to a discrete molecular assembly that can perform a mechanical motion or a set of motions in response to an external stimulus. These stimuli can include changes in temperature, pH, light irradiation, or the addition of specific chemical species.

The concept of molecular machines draws inspiration from biological systems, where many essential processes are carried out by natural molecular machines such as motor proteins (e.g., myosin, kinesin) and ribosomes. Researchers are actively developing artificial molecular machines with the goal of mimicking these biological functions and creating new technologies.

The design and synthesis of molecular machines involve intricate organic chemistry and supramolecular chemistry. Key components often include movable parts, such as rotating axles, sliding components, or contracting chains, connected by specific chemical bonds. The precise control over the movement of these components is crucial for their functionality.

Potential applications for molecular machines are vast and include areas like targeted drug delivery, nanoscale robotics, advanced materials with responsive properties, and novel sensing devices. While still largely in the research and development phase, molecular machines represent a frontier in nanotechnology with the promise of revolutionizing various scientific and technological fields. The study of molecular machines is a significant area within nanoscience and nanotechnology, pushing the boundaries of what is possible at the molecular level.
