The interaction of thermal energy from the environment with motional degrees of freedom is well known and often referred to as Brownian motion (also thermal motion). But in the case of polar molecules, the internal degrees ...
Physical chemists have devised a rolling DNA-based motor that's 1,000 times faster than any other synthetic DNA motor, giving it potential for real-world applications, such as disease diagnostics. Nature Nanotechnology is ...
Using large-scale computer modeling, researchers have shown the effects of confinement on macromolecules inside cells—and taken the first steps toward simulating a living cell, a capability that could allow them to ask 'what-if' ...
Though they're not quite ready for boarding a lá "Fantastic Voyage," nanoscale submarines created at Rice University are proving themselves seaworthy.
Sharks prowl the watery depths for their prey, lions stalk the tall-grass savannah, and bacteriophages, well, they've got snot. The thin layer of mucus that coats epithelial cells serves as the hunting ground for phages, ...
A Japanese researcher has investigated the contributions of active deformation dynamics of cell nuclei using the Brownian motion theory.
Particles floating in fluid perpetually flit about in all directions, a phenomenon referred to as Brownian motion. For example, proteins within our cells and pigment particles inside ink-jet printers wriggle and twitch their ...
UK scientists have pioneered a new way of manipulating several thousand atoms at a time, paving the way for building nanoscale electronic devices more quickly and easily at room temperature.
One of the striking features of self-organization in biomolecular systems is the capacity of assemblies of filamentous particles for synchronous motion. Physicists of Ludwig Maximilian University of Munich now provide new ...
For the first time ever, researchers have succeeded in creating arrangements of colloids – tiny particles suspended in a solution – and, importantly, they have managed to control their motion with high precision and speed. ...
