Carbon-coated microsensor for clean water applications (w/video)

Researchers have developed a water analyzer for continuous monitoring of trihalomethanes.

Selectively killing bacteria with magnetic nanoparticles

A novel nanoparticle system can specifically interact with adhesin molecules of a specific E. coli strain and cause agglutination through nanoparticle?bacteria complex. Applying treatment with an alternating magnetic field to such complex caused significant reduction in viability of the targeted bacteria.

Bacteria on surfaces -- strength of adhesion does not depend on size of contact area

Scientists have developed a method with which they can measure the contact area between a bacterium and the surface it is 'sitting' on. Interestingly a large contact area does not necessarily mean a large adhesive force.

DNA-functionalized graphene sensor for breath analysis

Researchers have demonstrated the enhanced sensing ability in a high humidity atmosphere of graphene sensors functionalized by single-stranded DNA, and proposed their novel sensing mechanism.

Racetrack memory - the future?

Synthetic ferrimagnet nanowires make more efficient memory devices.

Future materials are becoming 'topological'

Researchers experimentally developed the so-called Quantum Spin Hall effect in a two-dimensional material. Materials that display this phenomenon are called topological insulators.
