Annotation The use of nanomaterials is now included in many areas of human activity. A promising area of research for ecology, biology, agriculture and medicine is currently the development in the field of nanotechnology related to the production and use of ultrafine particles of metals and their oxides. In particular, a very broad trend in their use is associated with the creation of new microelements based on them. In this regard, of interest are only those forms of ultrafine particles, which do not have their own toxic effect, but have a more pronounced positive effect compared with substances in macrodisperse form. That is why it becomes relevant to study the safety issues of ultrafine particles of metals-trace elements and assess the possibility of biological risks associated with these applications, for example, as food additives. In this work, the hazard / safety of ultrafine particles of metals and their oxides on the recombinant Escherichia coli K12 TG1 strain with cloned luxCDABE Vibrio fischeri genes was investigated using bioluminescent analysis and the forms of ultrafine particles and their concentrations suitable for further use in agriculture and medicine were determined.
