House cleaning on the nanoscale: FAU scientists develop method for cleaning surfaces at the nanoscale

A team of scientists at Friedrich-Alexander Universität Erlangen-Nürnberg (FAU) has developed a novel mechanical cleaning method for surfaces on the nanoscale. The technique successfully removes even the tiniest contaminants down to the atomic scale, achieving an unprecedented level of cleanliness. The results of this study led by Prof. Dr. Erdmann Spiecker from the Department of Materials Science at FAU have now been published in the prestigious journal Nature Communications.

World's smallest broom

Inspiration for the technique was drawn from everyday life as cleaning with a broom works in a similar way. Of course, on the nanoscale instead of using an entire broom, only a single bristle in the form of a very small metal tip is used. This 'bristle' is pressed onto a surface and moved back and forth in a sweeping motion. 'It really is surprisingly similar to a regular broom,' says Prof. Spiecker, Chair of Micro- and Nanostructure Research. 'A broom removes loose particles such as dust or breadcrumbs, and it is no different on the nanoscale.' However, on small scales, the broom is not controlled by hand, but instead by joystick that controls a small piezo motor. Moreover, powerful electron microscopes are used to monitor and control the cleaning process in real time.

Plastic pollution is everywhere. Study reveals how it travels

Plastic pollution is ubiquitous today, with microplastic particles from disposable goods found in natural environments throughout the globe, including Antarctica. But how those particles move through and accumulate in the environment is poorly understood. Now a Princeton University study has revealed the mechanism by which microplastics, like Styrofoam, and particulate pollutants are carried long distances through soil and other porous media, with implications for preventing the spread and accumulation of contaminants in food and water sources.

How one fern hoards toxic arsenic in its fronds and doesn’t die

To survive high levels of arsenic, a fern sequesters the heavy metal in its shoots with the help of three proteins.

The Chinese brake fern looks unassuming. But Pteris vittatahas a superpower: It sucks up arsenic, tucks the toxic metal away in its fronds and lives to tell the tale.

No other plants or animals are known to match its ability to hoard the heavy metal. Now researchers have identified three genes essential to how the fern accumulates arsenic, according to a study in the May 20 Current Biology.

The fern shuttles the heavy metal, often found as arsenate in soil, from the plant’s roots to its shoots. There, the three genes make proteins that help corral arsenate as it moves through the plant’s cells and into a cellular compartment called a vacuole, where the arsenic is sequestered, the team found.

One protein, GAPC1, gloms onto the arsenate, possibly keeping it from doing damage during its journey. Another, OCT4, appears to help arsenate cross membranes, possibly into a structure where a third protein, GSTF1, transforms it into arsenite, the form stored by the plant. Tinkering with the genes caused the plants to die when exposed to arsenic, say Jody Banks, a botanist at Purdue University in West Lafayette, Ind., and her colleagues.

These ferns are already being used to draw arsenic out of soil in some contaminated areas.  It “takes a long time, but it’s really cheap,” compared with the millions of dollars it can cost to dig out contaminated dirt and clean it, Banks says. In one previous study, the ferns sucked up about half of the arsenic in heavily contaminated soil in five years.

P. vittata is a semi-tropical plant and can’t grow year-round everywhere. But splicing its genes into other plants might make it possible to put more cold-tolerant species to work removing arsenic, Banks says.
