Long-lasting insecticidal activity in plants driven by chlorogenic acid-loaded metal–organic frameworks Rincón, Irene Contreras Morales, María del Carmen Sierra Serrano, Beatriz Salles, Fabrice Rodríguez Diéguez, Antonio Rojas Macías, Sara Horcajada, Patricia Metal–organic frameworks (MOFs) possess a variety of interesting features related to their composition and structure that make them excellent candidates to be used in agriculture. However, few studies have reported their use as delivery agents of agrochemicals. In this work, the natural polyphenol chlorogenic acid (CGA) was entrapped via simple impregnation in the titanium aminoterephthalate MOF, MIL-125-NH2. A combination of experimental and computational techniques was used to understand and quantify the encapsulated CGA in MIL-125-NH2. Subsequently, CGA delivery studies were carried out in water at different pHs, showing a fast release of CGA during the first 2 h (17.3 ± 0.3% at pH = 6.5). In vivo studies were also performed against larvae of mealworm (Tenebrio molitor), evidencing the long-lasting insecticidal activity of CGA@MIL-125-NH2. This report demonstrates the potential of MOFs in the efficient release of agrochemicals, and paves the way to their study against in vivo models. 2024-05-16T08:21:00Z 2024-05-16T08:21:00Z 2024-04-15 journal article J.
