In this work, the gold nanoparticles (AuNPs) were synthesized using pulse-modulated radio-frequency atmospheric pressure glow discharge (pm-rf-APGD). By tailoring selected operating parameters of the pm-rf-APGD reaction-discharge system, the experimental conditions for the synthesis of raw-AuNPs with controlled optical and structural properties were found. The colloidal suspension of the size-controlled raw-AuNPs was mixed with an aqueous solution of gelatine and turmeric oil to produce an oil-in-water (O/W) nanoemulsion. AuNPs loaded into the nanoemulsion were characterized using ultraviolet-visible absorption spectrophotometry, dynamic light scattering, scanning electron microscopy supported by energy dispersive X-ray spectroscopy, and transmission electron microscopy equipped with selected area X-ray diffraction. Additionally, attenuated total reflectance Fourier-transform infrared spectroscopy was used to confirm the efficient functionalization of the AuNPs by nanoemulsion component. It was revealed that AuNPs were mostly spherical with an average size of 4.6 ± 1.0 nm and a face-centered cubic crystal system. The developed O/W nanoemulsion carrying AuNPs was applied towards the human breast cancer cell lines MCF7 and MDA-MB-231. It was found that it exhibited the cytotoxicity towards the breast cancer cells while were non-cytotoxic towards the non-tumour breast cells MCF10A. Moreover, it also inhibited the migration of the invasive cancer breast cells (line MDA-MB-231) and hence, could prevent the breast cancer metastasis.

Green nanoparticles are receiving great attention due to their broad fields of application. Plant extracts are promising sources, since the synergizing process is easy and cost-effective. Green synergism offers safer nanomaterials for both human health and the environment. The antimicrobial application of prepared nanoparticles is due to special capabilities at the nanoscale size. Green zinc oxide nanoparticles (ZnONPs) from lemongrass and turmeric revealed good antibacterial properties. Antibacterial active compounds were extracted from lemongrass and turmeric using methanol as a solvent. The extracts were introduced to zinc oxide solution to create synergized green ZnONPs and tested for their antibacterial properties. The samples were characterized by means of XRD, SEM, FTIR, and GC-MS. The zones of inhibition of synergized green ZnONPs were successfully measured using the disc diffusion method. The findings using gram-negative bacteria Escherichia coli. showed a higher antibacterial inhibition zone, with a diameter of 1.6 cm. The gram-positive bacteria, Staphylococcus aureus., showed low antibacterial inhibition. The addition of ZnO had positively revealed greater inhibition. Green ZnONPs synthesized using plant extracts will be further tested for various applications. HIGHLIGHTS Green zinc oxide nanoparticles (ZnONPs) prepared from lemongrass and turmerics Plant extracts are significant in reducing and stabilizing metallic ions The synergism of ZnONPs was successfully prepared from plant extract active and evaluated for their antibacterial activity using Staphylococcus aureus and Escherichia coli The zones of inhibition of synergized green ZnONPs measured using the disc diffusion method showed a higher antibacterial inhibition zone Antibacterial activity revealed the potential applications of green synergism of ZnONPs for treatment of contaminated water, medical applications, and cosmetics GRAPHICAL ABSTRACT

“…Expect for curcumin itself, ethosomal curcumin also showed the effect of promoting neovascularization in the second degree burns in rat [91] and curcumin cross-linked collagen aerogels also possesses proangiogenesis efficacy [92]. Oil of Curcuma longa also showed significant proangiogenesis activity [93]. All together are showing the effect of curcumin on promoting angiogenesis by regulating proangiogenesis factors.…”

Curcumin is a compound extracted from the Curcuma longa L, which possesses a wide range of pharmacological effects. However, few studies have collected scientific evidence on its dual effect on angiogenesis. The present review gathered the fragmented information available in the literature to discuss the dual effect and possible mechanisms of curcumin on angiogenesis. Available information concerning the effect of curcumin on angiogenesis is compiled from scientific databases, including PubMed and Web of Science using the key term (curcumin and angiogenesis). The results were reviewed to identify relevant articles. Related literature demonstrated that curcumin has antiangiogenesis effect via regulating multiple factors, including proangiogenesis factor VEGF, MMPs, and FGF, both in vivo and in vitro, and could promote angiogenesis under certain circumstances via these factors. This paper provided a short review on bidirectional action of curcumin, which should be useful for further study and application of this compound that require further studies.
