In the development of functional foods with therapeutic value, nanoliposomal carriers offer a promising strategy for enhancing the stability and efficacy of bioactive compounds in dairy matrices. This study evaluated the sensory acceptance and physicochemical stability of yogurt enriched with anthocyanin-loaded nanoliposomes during 21 days of refrigerated storage, assessing the impact of nanoencapsulation on compound preservation and quality. Nanoliposomes were synthesized using ultrasonic film dispersion and characterized for antioxidant and erythroprotective activities. Antioxidant capacity was assessed through DPPH, ABTS, and FRAP assays, while erythroprotective effects were evaluated via oxidative hemolysis using human erythrocytes of different ABO/RhD phenotypes. These were incorporated into artisanal yogurt, followed by physicochemical, microbiological, rheological, and sensory analyses. Anthocyanins showed strong antioxidant capacity, especially in ABTS (93.24%), DPPH (21.34%), and FRAP (1023.24 µM TE/g D.W.), reflecting their radical scavenging and reducing power. They also exhibited high erythroprotective activity, with greater antihemolytic effects in O RhD− blood and enhanced photoprotection against UVA in O RhD+ blood. Yogurt enriched with nanoliposomes showed improved color stability, reduced syneresis, and favorable rheological and sensory characteristics. These findings support nanoliposomes as molecular delivery systems in functional dairy matrices with potential nutraceutical applications targeting oxidative stress. Further work should explore molecular mechanisms and validate health-promoting effects.

La biosíntesis mediada por extractos de plantas promete ser un método sostenible para sintetizar nanomateriales. Es sabido que las biomoléculas presentes en extractos de plantas favorecen la formación de nanopartículas (NP’s) a la vez que las estabilizan y funcionalizan. Por tanto, el uso de plantas utilizadas en la herbolaria mexicana puede brindar a los nanomateriales obtenidos un gran impacto, como es el caso de Verbesina crocata (capitaneja). El objetivo del presente trabajo es reportar la biosíntesis de nanopartículas de plata/cloruro de plata (Ag/AgCl-NP’s) mediada por V. crocata, su caracterización y actividad fitotóxica en semillas de Raphanus sativus. Se encontró que los extractos acuosos de capitaneja son capaces de generar nanoestructuras, así como presentar efectos alelopáticos que disminuyen el desarrollo de R. sativus. En cambio, las Ag/AgCl-NP’s obtenidas presentan fitotoxicidad dependiente de la concentración en R. sativus. Los extractos de V. crocata son una alternativa viable para la biosíntesis de Ag/AgCl-NP’s.

Nanotechnology for promoting sustainable agriculture has emerged as an innovative alternative for controlling various pests. Nanopesticides are a tool capable of improving the efficiency of active ingredients, reducing required doses, and reducing environmental impact compared to conventional pesticides. This review analyzes the main types of nanopesticides, their mechanisms of action, benefits in crop protection, and current limitations, as well as their comparison with current commercial pesticides. It also discusses the potential risks associated with their use due to the lack of clear regulatory frameworks that guarantee their safe use. Finally, it highlights the need to promote interdisciplinary research and international regulations that drive the responsible development of nanopesticides, ensuring their role as a key tool in sustainable agriculture in the future.
