“…According to Pasquet, the antibacterial activity is significantly influenced by the concentration of Zn 2+ ions because a similar level of antibacterial activity against Pseudomonas aeruginosa was achieved using a ten‐times higher concentration of those ions than against Staphylococcus aureus . In other works it was mentioned that antibacterial properties are also shown by nanoparticles released from materials obtained by the “Green synthesis” method …”

The paper presents results of the studies on porous composites obtained using lyophilization method based on the solutions of the following polymers: chitosan, sodium alginate and polylactide, as well as ZnO-doped CaO-SiO 2 -P 2 O 5 bioglass.The researchers took the advantage of zinc ions demonstrating the bactericidal, immune-stimulating, and tissue-regenerating functions in the organism. The cytotoxicity of the composites was tested on L929 cells by means of the direct and the indirect contact method. The antibacterial properties were determined against the gram-negative bacteria Pseudomonas aeruginosa and the gram-positive bacteria Staphylococcus aureus at 24, 48 hours, and 7 days. The study demonstrated that changes due to cytotoxicity effect of the composites depend on the type of polymer and on the duration of contact with cells. The composite with polylactide was found to be the least toxic for L929 cells. ZnO added to the chemical composition of bioglass ensured bactericidal effects. The antibacterial properties of the composites depended on the ZnO content, bioglass grain size, polymer type, and composite microstructure. The composites presented in this paper are innovative as biomaterials for filling bone cavities because they can be a matrix for cells and have an antibacterial effect while supporting the regeneration of damaged tissue.

“…An Ultraviolet-visible spectrophotometer (Bio-tek) was used in a range of 250-800 nm (nanometer) to observe the absorbance spectra of the synthesized particles [44]. Fourier transform infrared spectroscopy (FTIR) was performed by FTIR-8400 s, Shimadzu [400 to 4000 cm (centimetre) −1 ] to find the probable functional group of significant biomolecules, the spice extract contains [45]. Zetasizer (NANO ZS90, Malvern Instruments Ltd, UK) was used to perform DLS (Dynamic Light Scattering) to investigate the stability and particle size distribution of synthesized nanoparticles [46].…”

Different conventional methods for synthesizing zinc oxide nano-particles (ZnONPs) significantly involves physical and chemical routes. But, often these synthesis processes are quite expensive and also involve the profuse use of many hazardous reagents. To overcome these problems, we have employed a convenient single step phytochemical synthesis of ZnONPs by using abundantly available bioresource, green cardamom. Aqueous extract of green cardamom served the purpose of reducing agent in the formation of ZnONPs, as the extract contains a high amount of flavonoids which hold great reducing properties. Various characterization analyses such as XRD, UV-vis, FTIR, SEM has been done to confirm the formation of ZnONPs and their size and shape. Antibacterial activity of the green ZnONPs was identified against Gram-positive as well as Gram-negative bacterial strains. Significant growth inhibition was found against all. The further anti-cancerous potential of synthesized nanoparticles was also studied on hepatocellular cell lines showing its potential to be a trustworthy anti-cancerous agent.

“…They investigated the effect of cu doping in ZnO nanoparticles on their biological and photocatalytic activities, which are significantly improved by Cu doping . In addition to that, the ZnO nanoparticles also synthesised using various leaf and plant extracts that includes, ocimum tenuiflorum , Tabernaemontana divaricata and Pedalium Murex , which are reported in the literature. Recently, Rosy Christy et al., investigated the effect of microwave irradiation in the Aloe vera plant extract mediated combustion process on their crystallite size and found that the microwave irradiation results in the reduction of crystallite size.…”

Metal oxide nanostructures receive great interest due to their unique size and shape dependent physicochemical and functional properties. With the rapid growth of metal oxide nanotechnology, their chemical synthesis processes have become the most promising one due to their simplicity and versatility. Among the various available chemical processes such as sol‐gel, hydrothermal, polyol and precipitation, the combustion process receives significant attention. In particular, the combustion process has been extensively explored for the synthesis of various nanostructured materials including metal oxides, which involves in the exothermic reaction upon thermal heating of precursor chemicals. Recently, the combustion process has been reinvented by using the various renewable resource‐based organic fuels, which receives increasing interest among global researchers. A wide range of plant/ leaf, fruit, flower, seed, peel, latex and tuber extracts along with the plant‐derived products have been explored in combustion process for the synthesis of various metal oxides. Hence, the present review is aimed to focus the recent advances in the combustion process by using renewable fuels for the synthesis of metal oxide nanostructures and also the emerging opportunities.
