The detection of small molecules interacting with DNA is important for the assessment potential hazards related to application rather toxic antitumor drugs, and distinguishing factors thermal oxidative damage. In this work, a novel electrochemical sensor has been proposed determination drugs. For assembling, glassy carbon electrode was modified black dispersed in DMF. After that, pillar [5]arene adsorbed Methylene blue Neutral red were consecutively electropolymerized onto layer. To increase...
Lichens often grow in microhabitats where they experience severe abiotic stresses. Some species respond to high UV radiation by synthesizing dark brown melanic pigments the upper cortex. However, unlike melanized structures of non-lichenized fungi, morphology layer lichens remains unstudied. Here, we analyzed morphology, ultrastructure, and elemental composition UV-exposed thalli lichen Lobaria pulmonaria (L.) Hoffm. Using light microscopy, detected a pigmented sensitive staining with...

The determination of antibiotics in food is important due to their negative effect on human health related antimicrobial resistance problem, renal toxicity, and allergic effects. We propose an impedimetric aptasensor for the kanamycin A (KANA), which was assembled glassy carbon electrode by deposition black a chitosan matrix followed carbodiimide binding aminated aptamer mixed with oligolactide derivative thiacalix[4]arene cone configuration. assembling monitored cyclic voltammetry,...
Li3V2(PO4)3 cathodes for Li-ion batteries (LIBs) were synthesized using a hydrothermal method with the subsequent annealing in an argon atmosphere to achieve optimal properties. The X-ray diffraction analysis confirmed material’s single-phase nature, while scanning electron microscopy revealed granular structure, indicating uniform particle size distribution, beneficial electrochemical performance. Magnetometry and spin resonance studies conducted investigate magnetic properties, confirming...
