The cover picture shows extraction of several valuable elements of the periodic table by DNA hydrogel, which is cut out in the form of a blossom from a Japanese cherry tree and stained with a pink DNA dye, ethidium bromide. In their Communication on page 619 ff., A. Zinchenko and co-workers outline the application of DNA cross-linked hydrogel for efficient extraction of noble and rare-earth metals. They demonstrate that placement of DNA hydrogel into a solution containing AuIII, PdII, or YbIII for several hours yields, in a single step, up to 70% of the metals from the aqueous phase in the hydrogel matrix.
