Biomineralization is an interdisciplinary scientific branch, on the border of chemistry, biology and materials science. This is a process that takes place in living organisms for the purpose of formation of biominerals. The presence of biominerals is diverse, and they have numerous biological functions such as protection, magnetic orientation, mechanical strength, ion storage and the like. Of the 60 currently known biominerals, approximately 20 % are amorphous and 80 % crystalline minerals. The pathological biomineralization process may also produce minerals that are not useful for the organism in which they are formed. For the scientific research of biominerals many experimental methods are used. For example for the precipitate analysis thermogravimetric analysis (TGA), scanning electron microscopy (SEM), transmission electron microscopy (TEM), atomic force microscopy (AFM), molecular Raman spectroscopy, infrared spectroscopy (IR) and dynamic light scattering (DLS) are one of the used methods. Except from the methods for the precipitate analysis there are also variety of the methods used for the analysis of the liquid phase and some of them are potentiometry, ionic chromatography and UV-VIS spectroscopy. In this bachelor thesis experimental methods and techniques of analysis of the precipitate are described and application of each method in biomineralization research is explained. For each described method an example in biomineralization research is given.
