The topics of antioxidant capacity, antibacterial activities, and antifungal activities are of great importance in the study of plant-derived NPs for several reasons. The study of antioxidant capacity is relevant because these substances neutralize free radicals, which are unstable molecules that can damage cells and contribute to the development of chronic diseases such as cancer, heart disease, and aging Investigating the antioxidant capacity of NPs can lead to the development of new dietary supplements and therapies to improve health. In terms of the food industry, natural antioxidants are used as preservatives to prevent food oxidation, extending shelf life and maintaining nutritional quality. Similarly, antibacterial activities are relevant in medicine as alternatives to current antibiotics, combating bacterial infections that are resistant to conventional treatments. Additionally, they can be used as biopesticides, offering a safer and more environmentally friendly alternative to traditional chemical pesticides, helping to control bacterial diseases in crops. Regarding antifungal activities, their study is relevant because fungal infections can be difficult to treat, and like bacteria, there is an increase in resistance to available antifungals. NPs with antifungal activity can lead to the development of new effective treatments for these infections. They can also be used as natural fungicides, protecting crops in a more sustainable way and reducing dependence on synthetic fungicides.
