Tomás Torroba, José Garcia and their team at the University of Burgos, Spain, have now developed a method for detecting Hg2+ and MeHg+ in fish samples that is both portable and easy to use. They combined a sulphur-containing fluorescent material, which mimics mercury binding sites in cells, with a polymer.
Destacados de Polymers (POLYMERS)
Researchers from the University of Burgos (Spain) have developed a fluorescent polymer that lights up in contact with mercury that may be present in fish. High levels of the metal were detected in samples of swordfish and tuna. According to the conclusions of another Spanish study, mercury exposure is linked to reduced foetal and placental growth in pregnant women.
Colour-changing sensor that spots TNT could be incorporated into clothing to be worn when clearing areas polluted by landmines
Chemists at the University of Burgos (Spain) have manufactured a sheet that changes colour in the presence of water contaminated with mercury. The results can be seen with the naked eye but when photographing the membrane with a mobile phone the concentration of this extremely toxic metal can be quantified.
A digital camera can detect the differences in the colors of various membranes submerged in mercury-tainted water.
