Description Raman tweezers represents a unique method for identification of different microorganisms on the basis of Raman scattering. Raman tweezers allows us to fix and sterile manipulate with the trapped object and in the same time check the growth, viability, response to the external environment etc by Raman signal evaluating. The investigations presented here include distinction of bacteria in general(staphylococcal cells), identification of bacteria strains (biofilm-positive and biofilm-negative) by using principal component analysis (PCA) and monitoring the influence of antibiotics.
