A tip for future nanoscale sensing

Commercially-available diamond tips used in atomic force microscopy (AFM) could help make quantum nanoscale sensing cost-effective and practical, A*STAR researchers have found.

The composition of ancient meteorites

A team of Japanese and American scientists has visualized meteorite components at higher resolution than ever before. Their efforts have resulted in an enhanced understanding of substances inside carbonaceous chondrites, ...

Measuring forces of living cells and microorganisms

Forces exerted by a living cell or a microorganism are tiny, often no larger than a few nanonewtons. For comparison, one nanonewton is the weight of one part in a billion of a typical chocolate bar. Yet, for biological cells ...

Self-sorting through molecular geometries

Researchers at Kanazawa University report in Communications Chemistry that certain pentagonal and hexagonal organic molecules exhibit self-sorting. The effect can be used to grow multilayered tubular structures that preserve ...

Capturing the surprising flexibility of crystal surfaces

Images taken using an atomic force microscope have allowed researchers to observe, for the first time, the flexible and dynamic changes that occur on the surfaces of 'porous coordination polymer' crystals when guest molecules ...

Assembly of fluctuating molecules in artificial cell membrane

Lipids and membrane proteins existing in cell membranes, which are located at the outermost layer of cells, are responsible for recognizing extracellular environments and transferring that information inside the cell. Due ...
