The influence of different extraction conditions on polyphenol content, antioxidant and antimicrobial activities of wild thyme
(Journal of Applied Research on Medicinal and Aromatic Plants, 2021)
The aims of the presented study were the investigation of the effect of different ultrasound-assisted extraction conditions (particle size, solid-to-solvent ratio, ethanol concentration and time) on polyphenol and flavonoid ...
In situ synthesis of Cu/Cu2O nanoparticles on the TEMPO oxidized cotton fabrics
(Springer, Dordrecht, 2018)
In situ synthesis of Cu/Cu2O nanoparticles on the cotton fabric discussed in this study relies on adsorption of Cu2+-ions by carboxylate groups generated through the TEMPO-mediated oxidation of cellulose and their subsequent ...
Bimetallic alginate nanocomposites: New antimicrobial biomaterials for biomedical application
(Elsevier Science Bv, Amsterdam, 2018)
Two bimetallic (Zn/Cu) alginate based nanocomposites, impregnated with carbonate or phosphate mineral phase, were prepared by a facile procedure. Mineralized samples exhibited different morphologies and properties when ...
Impregnation of cotton fabric with silver nanoparticles synthesized by dextran isolated from bacterial species Leuconostoc mesenteroides T3
(Elsevier Sci Ltd, Oxford, 2015)
This study was aimed to highlight the possibility of cotton fabric impregnation with silver nanoparticles synthesized by dextran isolated from Leuconostoc mesenteroides T3 in order to obtain antimicrobial properties. The ...
Tailoring the physico-chemical and antimicrobial properties of agar-based films by in situ formation of Cu-mineral phase
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
New agar-based composite films with increasing Cu-carbonate and Cu-phosphate mineral phase content were prepared by in situ mineralization and solvent casting method. SEM and optical analysis revealed that Cu-carbonate ...
Synthesis and antimicrobial properties of Zn-mineralized alginate nanocomposites
(Elsevier Sci Ltd, Oxford, 2017)
New bioactive and antimicrobial biomaterials were produced by alginate-mediated biomineralization with Zn-mineral phase. The synthesis procedure is simple, cost-effective and resulted in. two different Zn-mineralized ...
Mineralized agar-based nanocomposite films: Potential food packaging materials with antimicrobial properties
(Elsevier Sci Ltd, Oxford, 2017)
New mineralized, agar-based nanocomposite films (Zn-carbonate and Zn-phosphate/agar) were produced by a combination of in situ precipitation and a casting method. The presence of minerals significantly influenced the ...
Recovery of bioactive molecules from Hypericum perforatum L. dust using microwave-assisted extraction
(Springer Science and Business Media Deutschland GmbH, 2024)
Microwave-assisted extraction (MAE) conditions were optimized to improve extract quality of medicinal herb — Hypericum perforatum L. (St. John’s wort) dust. Response surface methodology was applied initially to obtain the ...
Nano-finishing of cellulose textile materials with copper and copper oxide nanoparticles
(Springer, Dordrecht, 2019)
Nano-finishing of textile materials with metal and metal oxide nanoparticles has been in the focus of science and textile industry almost two decades. The emergence of bacteria resistance to silver nanoparticles due to ...
Synthesis, characterization and SAR studies of bis(imino)pyridines as antioxidants, acetylcholinesterase inhibitors and antimicrobial agents
(Academic Press Inc Elsevier Science, San Diego, 2020)
In this study we synthesized a series of sixteen bis(imino)pyridines (BIPs) starting from 2,6-diaminopyridine and various aromatic aldehydes, and evaluated their antioxidant, antibacterial, antifungal and acetylcholinesterase ...
