• , resulting in OphtNE-3.70% with a droplet diameter of 173 nm and a zeta potential of −44.7 mV. The addition of Kolliphor® HS15 in OphtNE-3.66%(K1%) initially reduced the droplet size to 70.8 nm and enhanced the antioxidant effect. Although the droplet size and polydispersity index increased after more than

• >75% cell viability in L929 cells and ~10% 2,2-diphenyl-1-picrylhydrazyl (DPPH) antioxidant effect. These findings support the multifunctional potential (cytocompatibility and antioxidant) of sterile OphtNE-3.66%(K1%) for the treatment of DED, emphasizing the need for in vivo studies to ensure its

Flavonoids, stilbenes, and anthraquinones in its structure are the main phenolic components that provide a potential antioxidant effect to this plant. The young shoots and leaf stems

• had a long-term effect due to the stability of EGCG. The findings of the study underline the potential of antioxidant and antiaging effects of the developed ethosomal formulations for use in the cosmetic field. Keywords: antioxidant effect; antiaging effect; epigallocatechin gallate; ethosomal gel

• different plant extracts other than EGCG [15]. In this current study, we aimed to develop ethosomal formulations for the use of EGCG in cosmetics due to its widely known strong antioxidant effect, which has been emphasized in many studies. In addition, we focused on enhancing the long-term antioxidant

In previous studies, the cytotoxic effect of EGCG, whose antioxidant effect has been proven many times, has been investigated, especially on cancer cell lines. Although there is no cytotoxicity study on the L929

The results suggested that phenolic compounds immobilized on the γ-Fe2O3 nanoparticles preserved their antioxidant effect to reduce ROS levels inside the cells. Conclusion Magnetic nanoparticles are increasingly used for biomagnetic separation

The proposed mechanism for the formation of the MWNTs from graphene is as follows [31]: (1) the production of graphene layers by ultrasonication of graphite in DMF, (2) the antioxidant effect of Fc–CHO which reduces the concentration of radical reactive species, reducing the cutting
