Nanoelements in Mendeleev’s Periodic Table. Copper Subgroup

The 150th anniversary of the Mendeleev’s Periodic Table of elements requires scientists to rethink the outstanding role of this fundamental law in modern areas of chemistry, including such interdisciplinary and high-tech fields as nanochemistry and nanomaterials. The situation analysis shows that the most “nanotechnologically” popular elements belong to 1st, 2nd and partially to the 3rd periods, wherein a special practically important role is played by the noble metals because of their clear «specialization» in the development and implementation of new analytical techniques, in particular, the surface-enhanced Raman spectroscopy (SERS). There is an obvious need to develop and introduce fundamentally new, unique approaches and tools for the analysis of functioning living tissue structures. And SERS is precisely such a method, which implements multiplex, nonivasive spatially- and time-resolved control of chromoproteins at the extremely low concentrations in small volumes of samples of biological objects (tissues, cells, cell structures / organelles), and is an important innovative method of practical biomedical diagnostics.
