“…Moreover, there has been interest in the medicaluses of copper, in particular as a complexing ion of known biologically active ligands and drugs. Throughout the years of scientific research copper(II) complexes have been found to possess various activities such as antiulcer [46], antiamoebic [47], antidiabetic [48] anticonvulsant [49], anti-inflammatory [50][51][52], antimicrobial [53] and antitumor [54]. In particular, anti-inflammatory, anti-microbial and anti-cancer activity of copper complexes has been studied.…”

“…The necessity is the treatment of surfaces, tools and working materials by decontaminants. Application of antibiotics is not always a suitable choice, since they can be transferred into the treated material [ 3 ]. Organic compounds used for disinfection have some disadvantages including toxicity to the human body [ 4 ].…”

The present experiment describes a synthesis process of composites based on graphene oxide, which was tested as a carrier for composites of metal- or metalloid-based nanoparticles (Cu, Zn, Mn, Ag, AgP, Se) and subsequently examined as an antimicrobial agent for some bacterial strains (Staphylococcus aureus (S. aureus), methicillin-resistant Staphylococcus aureus (MRSA) and Escherichia coli (E. coli). The composites were first applied at a concentration of 300 µM on all types of model organisms and their effect was observed by spectrophotometric analysis, which showed a decrease in absorbance values in comparison with the control, untreated strain. The most pronounced inhibition (87.4%) of S. aureus growth was observed after the application of graphene oxide composite with selenium nanoparticles compared to control. Moreover, the application of the composite with silver and silver phosphate nanoparticles showed the decrease of 68.8% and 56.8%, respectively. For all the tested composites, the observed antimicrobial effect was found in the range of 26% to 87.4%. Interestingly, the effects of the composites with selenium nanoparticles significantly differed in Gram-positive (G+) and Gram-negative (G−) bacteria. The effects of composites on bacterial cultures of S. aureus and MRSA, the representatives of G+ bacteria, increased with increasing concentrations. On the other hand, the effects of the same composites on G− bacteria E. coli was observed only in the highest applied concentration.

A series of newly synthesized coumarin‐based mixed‐ligand copper complexes with 1,10‐phenanthroline (Ph) were investigated by means of thermogravimetry, differential thermogravimetry, differential scanning calorimetry (DSC), electronic spectra and magnetic measurements. Structural and spectroscopic properties of neutral bidentate ligands as well as all complexes were studied on the basis of mass spectra, NMR (1H and 13C) spectra, FT‐IR spectrophotometry and elemental analyses. IR spectral data suggest tetra‐coordinated N2O2 bonding of ligand toward metal ion. Dynamic scan of DSC experiments for copper complexes were obtained at different heating rates (2.5–20°C min−1). Isoconversion methods of Kissinger and Ozawa were used for the determination of the pre‐exponential factor (A), activation energy (Ea) and order of reaction (n). Kinetic parameters for second‐step degradation obtained by Kissinger's and Ozawa's methods are in good agreement. The results indicate that complexes are much stronger free radical scavenger and antioxidant compounds than ligands. Antimycobacterial screening of ligand and its copper compound against Mycobacterium tuberculosis shows clear enhancement in antitubercular activity upon copper complexation. Also good antimicrobial activities of the complexes against Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Salmonella typhus, Aspergillus niger, Candida albicans and Aspergillus clavatus have been found compared to its free ligands.
