The work is devoted synthesis, investigation and application of composites based on calcium carbonate microspheres, with embedded nanoparticles of magnetite (Fe3O4), coated by silver nanostructured shell. This composite (SERS-substrate) was used for surface-enhanced Raman spectra (SERS) registration of rhodamine 6G and different pharmaceuticals such as ipratropium bromide, chloramphenicol, propranolol, pindolol, tamoxifen, diltiazem.

Natural composite structures, such as horn bones and nacre (or socalled mother-of-pearl), are characterized by a structural organization ordered at the nanoscale. This material architecture has attracted a wide interest order to develop new hybrid composite materials with tunable mechanical properties. The сurrent review aimed to establish the prospects for the development of artificial methods for synthesis of mechanically strong biomimetic materials.
