The production of more advanced sensors to improve the detection of pesticides in water and other environmental samples has been helped by a grant of almost 1.23 million euro from the EU’s Framework Programme.
With seven partners from four EU member states, the SAFEGUARD project was designed to systematically evaluate specifically tailored enzymes as the basis for the production of sensors that are able to detect significantly lower levels of pesticides than has previously been possible.
“This project permits detection limits of pesticides such as Paraxon for environmental protection applications down to concentrations (of 1x10-17M) that until now were unobtainable”, says Professor Seamus Higson of Cranfield University. “The enzymes will be produced by molecular biology techniques to be selectively responsive and sensitive to the presence of pesticides. They will be the basis for the production of established sensors, able to rapidly and routinely quantify pesticides in water and other environmental samples at concentrations below recommended acceptance levels.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.
The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
