The main aim of the project is to develop a functional prototype of a portable Laser Induced Breakdown Spectroscope (LIBS) for analysis of biological samples. This will enable a rapid, precise and safe analysis of elements, without any need for sample extraction and their transport to a laboratory. Currently, there are devices designed (optimized) for metallurgical and geological samples, but not for biological ones. New methods of measurement and algorithms for the analysis (classification) of spectra need to be developed.
