Biosensor for heavy metals

A team of Empa scientists has developed a biosensor which allows them to detect elevated concentrations of copper in a simple, quick and economic way. Copper, like other heavy metals is problematic in high concentrations, ...

Gold 'micro jewels' from the 3-D printer

Thanks to a laser technique that ejects ultra-tiny droplets of metal, it is now possible to print 3-D metal structures—not only simple 'piles' of droplets, but complex overhanging structures, as well, like a helix measuring ...

Clicking TC-99m SPECT probes together

(PhysOrg.com) -- Radioactively labeled compounds are important for use as imaging probes or radiotherapeutic agents. Most radioisotopes with suitable decay properties are transition metals or elements with metallic character. ...

Novel imaging approach reveals how ancient amulet was made

At 6000 years old, this copper amulet is the earliest lost-wax cast object known. Now, researchers have finally discovered how it was made, using a novel UV-visible photoluminescence spectral imaging approach. All the parameters ...
