Мета роботи. Обґрунтувати склад і технологію перспективних косметичних засобів з наночастинками срібла, золота і міді. Матеріали і методи. Для розробки косметичних засобів використовували колоїдні розчини наночастинок срібла, золота і міді, синтезовані в Інституті біоколоїдної хімії імені Ф.Д.Овчаренка НАН України. Антимікробну активність колоїдни...
Article
Cadmium compounds are highly toxic substances characterized by mutagenic, genotoxic and carcinogenic effects, and having high cumulative properties. Application of cadmium nanoparticles (NPs) in medicine stimulates the study of their mechanism of action at the cellular level and at the level of organs and systems, determination of biomarkers of the...
Article
In the last decade, ferromagnetic nanoparticles that are able to be heated under an AMF (alternating magnetic field) have gained considerable interest in the field of nanotechnology. The current study explores the peculiarity of the synthesis and the properties of Fe3O4 and (La, Sr)MnO3 nanoparticles by cryochemical and sol-gel technology, as well...

Water dispersion of 30 nm spherical silver nanoparticles (AgNP) has been synthesized and characterized as biosafe according to the parameters of cytotoxicity, genotoxicity, mutagenicity and biochemical markers. AgNP’ high bactericidal effectiveness in vitro has been revealed against wide spectra of pathogens (Escherichia coli, Staphylococcus aureus...

An increase of the number and the variety of anthropogenic sources of radio-frequency electromagnetic fields (RF-EMFs) causes a high interest in studying the effects of non-ionizing radio waves on living organisms. Amongst many biological targets, the DNA molecule has received the greatest attention with respect to potential RF-EMFs damage. The aim...

This article presents results, which demonstrate the significant efficacy of the studied silver nanoparticles solution (average size 30 nm), synthesized at the Institute of Biocolloidal Chemistry named after F. Ovcharenko NAS of Ukraine, as a potential antimicrobial substance for use in oral and maxillofacial surgery for treatment of acute purulent...
Article
The expressed changes in the bacteria cells' plasma membrane ATPase activity values cells of Escherichia coli, which are used in the manufacturing of vaccines against cattle colienterotoxemia, have been revealed under the influence of lyophilization/rehydration process. Influence of gold (average size 20, 30, 45 nm) and silver (30 nm) nanoparticles...
Article
The transconjugate containing hybrid plasmid (Te(R)Zn(R)lux+) was obtained using the conjugation method on Pseudomonasfragi T2(5) (Te(R)ZnR) strain and bioluminescent strain Protobacterium phosphoreum B7071 (lux+). The expression regulation of lux-genes on the obtained plasmid is carried out by promotor-operational area conjointly with zinc resista...
Article
Effect of exogenous lipids on the morphology and enzymatic activity of Bacillus cereus B4368 membrane has been studied. Specific character of different lipids action on the membrane enzyme activity was found. This peculiarity had been taken into account by using liposomes in biological systems.
Article
Transconjugant strain of bacteria degraders of alkylnaphthalenesulphonate (ANS) - P Pseudomonas alcaligenes TR (NPL-41) was obtained under conditions of ANS selective pressure and flow cultivation of bacteria destructors of alkylbenzene sulphonate (ABS) P.alcaligenes TR (pABS) and naphthalene P. putida BS438 (NPL-41) and their immobilization on an...
