Abstract
The dynamics of the de novo generation of biogenic metal nanoparticles clearly reflects the features of the interaction of the used cells with cations. With this taken into account, we develop a methodological approach that makes it possible to assess the level of metabolic activity of cells by measuring the linear parameters of biogenic metal nanoparticles that are formed in situ in minutes (DBNG, detection of biogenic-nanoparticle generation/growth). This work shows examples of the practical use of this research approach, which makes it possible to detect the contamination of growth media, assess the physiological state of pure cultures of microorganisms during their cultivation, compare the physiological state of natural microbial communities under changing environmental conditions, identify metabolic differences when comparing genetically closely related cultures of microorganisms, search for cultures with an increased level of target metabolic activities for practical use, and differentiate types of human tumor tissues.
