Carob ( L.) is a tree crop cultivated extensively in the eastern Mediterranean regions but that has become naturalized in other regions as well. The present study focused on the green synthesis of zinc oxide nanoparticles (ZnONPs) from Carob and their evaluation for antimicrobial activity in bacteria and fungi. The synthesized ZnONPs showed strong antibacterial activity against ATCC 25 923 (92%). The NPs inhibited the growth of pathogenic yeast strains, including ATCC90028, ATCC6258, and ATCC14116, by 90%, 91%, and 82%, respectively, compared to the control. Fungal inhibition zones with the ZnONPs were 88.67% and 90%, respectively, larger for 15UA005 and ATCC204305, compared to control fungal growth. This study provides novel information relevant for plant-based development of new and potentially antimicrobial ZnONPs based on extracts. In particular, the development and application of phytogenic nanoparticles enhances the biocompatibility of nano-scale materials, thereby allowing to tune effects to prevent adverse outcomes in non-target biological systems.

There is a need for advanced developments to battle aggressive breast cancer variations and to address treatment resistance. In cancer therapy, ZnO nanoparticles (NPs) possess the ability to selectively and effectively induce apoptosis in cancer cells. There is an urgent necessity to create novel anti-cancer therapies, and recent studies indicate that ZnO nanoparticles have significant promise.

Burn care and treatment differ markedly from other types of wounds, as they are significantly more prone to infections and struggle to maintain fluid balance post-burn. Moreover, the limited self-healing abilities exacerbate the likelihood of scar formation, further complicating the recovery process. To tackle these issues, an asymmetric wound dressing comprising a quercetin-loaded poly(3-hydroxybutyrate-co-4-hydroxybutyrate) (P34HB@Qu) hydrophilic layer and a zinc oxide nanoparticle-loaded, thermally treated polyvinylidene fluoride (HPVDF@ZnO) hydrophobic layer is designed.

Zinc oxide nanoparticles (ZnO NPs) with varying levels of nitrogen (N) doping were synthesized using a straightforward sol-gel approach. The morphology and microstructure of the N-doped ZnO NPs were examined through techniques such as SEM, XRD, photoluminescence, and Raman spectroscopy. The characterization revealed visible changes in the morphology and microstructure resulting from the incorporation of nitrogen into the ZnO lattice.

The present study aimed to investigate the ability of an aqueous extract derived from mustard seed meal to counteract the effects of endotoxin lipopolysaccharide (LPS) on the intestinal epithelium. Caco-2 cells were cultured together with HT29-MTX and used as a cellular model to analyze critical intestinal parameters, such as renewal, integrity, innate immunity, and signaling pathway. Byproducts of mustard seed oil extraction are rich in soluble polysaccharides, proteins, allyl isothiocyanates, and phenolic acids, which are known as powerful antioxidants with antimicrobial and antifungal properties.
