Документ Ecological synthesis of silver nanoparticles using bacteria(2020) Laziuka, Yuliya; Skrotska, Oksana; Kharchenko, YevgenDue to the potential use of nanomaterials, there is a need to investigate environmentally friendly technologies for the synthesis of nanoparticles. Traditionally, nanoparticles are synthesized by physical and chemical methods. However, these methods are characterized by the use of hazardous and aggressive substances, which are harmful to the environment and cause serious health problems. It should be noted that the production of nanoparticles using microorganisms, in particular bacteria, is environmentally safe, since this method of synthesis does not require the use of toxic materials.Документ Biosynthesis of silver nanoparticles by Saccharomyces cerevisiae M437(2021) Kharchenko, Yevgen; Skrotska, Oksana; Laziuka, Yuliya; Marchenko (Potapenko), ValeriaSilver nanoparticles (AgNPs) are widely used in medicine and pharmaceuticals as biosensors, diagnostic agents, targeted drug delivery agents with controlled release, as antimicrobial, and anticancer agents. AgNPs are mainly produced by chemical synthesis. The disadvantages of this method: the use of toxic substances (ethylene glycol, hydrazine, and sodium borohydride), low yield of nanoparticles, expensive isolation, and purification. Therefore, it is important to find a safe and effective synthesis method, for example using green synthesis. Biosynthesis can provide a high yield of particles stabilized by natural substances that have high biocompatibility. Biological synthesis can take place both intracellular and extracellular. Cell extracts can also be used for biosynthesis. In this study, the purpose was to synthesize silver nanoparticles using metabolites contained in the supernatant of Saccharomyces cerevisiae M437.Документ Environmental belief of students in higher technical educational institutions – the path to harmonious relationship between technogenic society and nature(2011) Skrotska, Oksana; Voloshina, Iryna; Krasinko, Victoria; Lych (Tkachenko), Inna; Teterina, SvitlanaThe article is devoted to the consideration of ways of the topical problems decision which get in way of harmonization of relations between technogenic society and the nature. It also devoted to the analysis of state of training of specialists on ecological orientation in the higher technical educational institutions.
