'Lab on a chip' can measure protein-DNA interactions

New nanophotonic tweezers developed by Cornell researchers can fit on a chip less than one-inch square, making it easier and more efficient to manipulate single molecules using light in order to investigate biological systems.

ESR-STM on single molecules and molecule-based structures

Scaling down information devices to the atomic scale has brought the interest of using individual spins as a basic unit for data storage. This requires precise detection and control of spin states and a better understanding ...

In situ extraction and detection of DNA using nanopores

Being able to detect DNA from a single cell is important for the detection of diseases and genetic disorders. Measuring single DNA molecules has been possible for some time; however, directly detecting samples at the point ...

Shielding ultracold molecules with microwaves

Ultracold molecules are promising for applications in new quantum technologies. Unfortunately, these molecules are destroyed upon colliding with each other. Researchers at Harvard University, MIT, Korea University and Radboud ...

How chemical reactions compute

A single molecule contains a wealth of information. It includes not only the number of each kind of constituent atom, but also how they're arranged and how they attach to each other. And during chemical reactions, that information ...

Appearance of cystic fibrosis at the molecular scale

Despite remarkable medical advances over the last years, cystic fibrosis remains the most prevalent lethal genetic disease. It is due to mutations in the CFTR protein which is normally required to maintain proper fluid balances ...
