Ions are an essential tool in chip manufacturing, but these electrically charged atoms can also be used to produce nano-sieves with homogeneously distributed pores. A particularly large number of electrons, however, must be removed from the atoms for this purpose. Such highly charged ions either lose a surprisingly large amount of energy or almost no energy at all as they pass through a membrane that measures merely one nanometer in thickness. This discovery is an important step towards developing novel types of electronic components made of graphene.

It's a familiar trope in science fiction: In enemy territory, activate your cloaking device. And real-world viruses use similar tactics to make themselves invisible to the immune system. Now scientists have mimicked these viral tactics to build the first DNA nanodevices that survive the body's immune defenses.

A bullet fired through a block of wood will slow down. In a similar way, ions are decelerated when they pass through a solid material: the thicker the material, the larger the energy loss will be. However, this picture breaks down in ultra-thin target materials, which only consist of a few layers of atoms.

Researchers have synthesized a new class of macromolecules that self-assemble into various ordered structures with feature sizes smaller than 10 nanometers. Called 'giant surfactants', these large molecules mimic the structural features of small surfactants but have been transformed into functional molecular nanoparticles by being 'clicked' with polymer chains. The resulting materials are unique because they bridge the gap between small molecule surfactants and traditional block copolymers and thus possess an interesting duality in their self-assembly behaviors.

Using nanodot technology, Berkeley Lab researchers have demonstrated the first size-based form of chromatography that can be used to study the membranes of living cells. This unique physical approach to probing cellular membrane structures can reveal information critical to whether a cell lives or dies, remains normal or turns cancerous, that can't be obtained through conventional microscopy.
