Among them, light-triggered molecular motors are a category of photochemical switches with two parts that produce unidirectional mechanical motion at the nanoscale, on demand, upon external stimuli.

The molecular motor is made up of two identical halves, linked by a double carbon-carbon bond that acts as the axle. By sequentially exposing the molecule to UV-light and heat, unidirectional ...

Scientists from Delft, Vienna, and Lausanne discovered that the protein machines that shape our DNA can switch direction.

The first molecular motor created by Ben Feringa was described 25 years ago (on 9-9-1999) in the journal Nature. It brought Feringa a 1/3 share in the 2016 Nobel Prize in Chemistry.

DNA motors found to switch gears Date: January 16, 2025 Source: Delft University of Technology Summary: Scientists have discovered that the protein machines that shape our DNA can switch direction ...

Molecular machines can already act as switches, shuttles, motors, or pumps, but most only work in solution, where it’s difficult to coordinate their activity. To help the minute gadgets perform ...

Molecular switches are nanoscale devices that change state in response to stimuli, enabling applications in molecular electronics, drug delivery, sensors, and smart materials.

Molecular motors are biological nanomachines that convert chemical energy into mechanical work, powering essential cellular processes and inspiring artificial nanodevices.

Scientists used molecular motors to manipulate the protein matrix on which bone marrow-derived mesenchymal stem cells are grown. Rotating motors altered the protein structure, which resulted in a ...

Molecular switches provide a "bottom-up" approach for nanoelectronics, allowing for miniaturization beyond the constraints of silicon. By enabling precise control at the molecular level, these ...
