A molecular model shows two macrocycles interlocked like links in a chain, with additional atoms attached on the side of one ring. This conceptual version of the catenane made by Michael Kathan and ...

Fast-scanning atomic force microscopy imaging of the molecule at two different time points shows positional shifts along the polymer chain on the left. On the right, the molecular structure of PEG ...

The structural design of molecular machines and motors endows them with externally controlled directional motion at the molecular scale. Molecular machines based on both interlocked and ...

Understanding molecular diversity is fundamental to biomedical research and diagnostics, but existing analytical tools struggle to distinguish subtle variations in the structure or composition among ...

(Nanowerk News) Artificial molecular machines, nanoscale machines consisting of a few molecules, offer the potential to transform fields involving catalysts, molecular electronics, medicines, and ...

A complex molecular machine, the spliceosome, ensures that the genetic information from the genome, after being transcribed into mRNA precursors, is correctly assembled into mature mRNA. Splicing is a ...

Trying to untangle a knot in a mess of strings can be frustrating and time-consuming. But not so for molecular machines—molecules that convert chemical energy into mechanical work and motion. Machines ...

Professor Jiawen Chen and Associate Researcher Yan Wang from South China Normal University, in collaboration with Professor Ben L. Feringa's team at the University of Groningen, Netherlands, designed ...

Scientists have discovered a new property of the molecular motors that shape our chromosomes. While six years ago they found that these so-called SMC motor proteins make long loops in our DNA, they ...

Scientists have built DNA-based nanocircuits that reset with heat, enabling reusable molecular systems for tasks like cargo sorting and pattern recognition. (Nanowerk News) Though it might seem like ...
