Paper-based lateral flow device to detect uranium in groundwater

The presence of uranium in groundwater can lead to severe health problems, from renal failure to cancer. Standard methods to detect uranium involve time-consuming processes and expensive, non-portable equipment. Measurements ...

Photoelectrode that can harvest 85 percent of visible light

Scientists have developed a photoelectrode that can harvest 85 percent of visible light in a 30 nanometers-thin semiconductor layer between gold layers, converting light energy 11 times more efficiently than previous methods.

Nanoparticles form supercrystals under pressure

Self-assembly and crystallisation of nanoparticles (NPs) is generally a complex process, based on the evaporation or precipitation of NP-building blocks. Obtaining high-quality supercrystals is slow, dependent on forming ...

Why size matters for gold as a catalyst

Gold is the noblest metal—the most resistant to oxidation. However, nano-size gold has a unique ability to perform as a catalyst, even at low temperatures. The underlying mechanism for this size-dependent change in properties ...

A novel nanoactuator system has been developed

Researchers at University of Jyväskylä (Finland) and University of Tampere (Finland) together with BioNavis Ltd (Finland) have developed a novel nanoactuator system, where conformation of biomolecule can be tuned by electric ...

Water matters to metal nanoparticles

When you purchase anything from makeup to paint to sunscreen, chances are it contains engineered nanoparticles. These nanoscale materials have properties that are revolutionizing products—from medicine to agriculture to ...

Large supercrystals promise superior sensors

Using an artful combination of nanotechnology and basic chemistry, Sandia National Laboratories researchers have encouraged gold nanoparticles to self-assemble into unusually large supercrystals that could significantly improve ...

Gold nanoparticles to find applications in hydrogen economy

An international team of scientist of Peter the Great St. Petersburg Polytechnic University (SPbPU), Leibniz University Hannover (Leibniz Universität Hannover) and the Ioffe Institute report a way to improve nanocomposite ...
