“…Calcium nitrate (Sigma-Aldrich) was used for the preparation of CaO NPs. Ca(NO 3 ) 2 was dehydrated in an oven at 150°C for 2 h and then ground using a SPEX8000 apparatus with a vial and balls of tungsten carbide and a ball-to-powder weight ratio (BPR) of 10:1 (Fritsch, Mini-mill-Pulverisette) [22]. The prepared CaO NPs were characterized by transmission electron microscopy, Fourier transform infrared spectroscopy (FTIR) and UV-Vis spectroscopy [23].…”

“…Chemically synthesized CaO NPs nanoparticles were screened by placing a droplet of the nanoparticles onto negative carbon-coated copper grids and drying them in the air. The TEM micrographs of the prepared NPs were analyzed with a JEOL TEM 100 CXII (Electron Microscope Unit, Assiut University, Egypt) where the size and shape of CaO NPs were investigated considering the method [22].…”

The extensive use of nanoparticles (NPs) in diverse applications causes their localization to aquatic habitats, affecting the metabolic products of primary producers in aquatic ecosystems, such as algae. Synthesized calcium oxide nanoparticles (CaO NPs) are of the scarcely studied NPs. Thus, the current work proposed that the exposure to CaO NPs may instigate metabolic pathway to be higher than that of normally growing algae, and positively stimulate algal biomass. In this respect, this research was undertaken to study the exposure effect of CaO NPs (0, 20, 40, 60, 80, and 100 µg mL −1 ) on the growth, photosynthesis, respiration, oxidative stress, antioxidants, and lipid production of the microalga Coccomyxa chodatii SAG 216-2. The results showed that the algal growth concomitant with chlorophyll content, photosynthesis, and calcium content increased in response to CaO NPs. The contents of biomolecules such as proteins, amino acids, and carbohydrates were also promoted by CaO NPs with variant degrees. Furthermore, lipid production was enhanced by the applied nanoparticles. CaO NPs induced the accumulation of hydrogen peroxide, while lipid peroxidation was reduced, revealing no oxidative behavior of the applied nanoparticles on alga. Also, CaO NPs have a triggering effect on the antioxidant enzymes such as superoxide dismutase, catalase, ascorbate peroxidase, and guaiacol peroxidase. The results recommended the importance of the level of 60 µg mL −1 CaO NPs on lipid production (with increasing percentage of 65% compared to control) and the highest dry matter acquisition of C. chodatii. This study recommended the feasibility of an integrated treatment strategy of CaO NPs in augmenting biomass, metabolic up-regulations, and lipid accumulation in C. chodatii.

“…Calcium oxide nanoparticles can exhibit antimicrobial activity against both Gram-positive and Gram-negative bacteria and fungi, they are non-toxic and cheap to produce. Their action is related to the induction of the production of oxygen radicals and alkalization of the solutions in which they are located, causing damage to bacterial membranes and cell death [21][22][23].…”

Growing international problem with pathogens acquiring resistance to antibiotics is the reason for the search for bactericidal substances against which microorganisms cannot become resistant. The aim of this study was to synthesize inorganic-organic nanohybrids and obtain materials with antimicrobial effects. Chitosan (CS) was deposited on nanocomposite carriers such as calcium oxide with titanium dioxide (CaO-TiO2), magnesium oxide with titanium dioxide (MgO-TiO2) and copper(II) oxide with titanium dioxide (CuO-TiO2). The efficiency of the process was examined at varying concentrations of chitosan and temperature. The parameters for nanohybrids synthesis were selected based on the highest amount of nano-chitosan deposited on the nanohybrids – for each carrier, the process conditions were as follows: chitosan solution at 5 g/L and 20°C. The materials were obtained using these parameters and were used for microbiological tests against E. coli ATCC 25922, S. aureus ATCC 25923 and C. albicans ATCC 10231. The growth inhibitory activity of the obtained materials was qualitatively defined. These results suggest that the synthesized nanohybrids and nanocomposites exhibit biostatic action. The material with the broadest effect was the CuO-TiO2-CS hybrid, which had biostatic properties against all tested strains at a minimal concentration of 1250 μg/mL. Further research is required to find eco-friendly, non-toxic, and more effective antimicrobials with a broad action to prevent the acquisition of resistance.
