Resumen
La nanotecnología es un área de la ciencia emergente que involucra la ingeniería de partículas
nanométricas de diversos materiales (Khare et al., 2014). De acuerdo con la Agencia de Protección Ambiental de Estados Unidos (EPA, por sus siglas en inglés), la nanotecnología se define como "la creación y uso de estructuras, dispositivos y sistemas que tienen propiedades y funciones novedosas debido a su pequeño tamaño". Estas partículas y estructuras moleculares tienen dimensiones en el rango nanométrico (típicamente entre 1 y 100 nm en al menos una dimensión) (Hobson, 2011). Es debido a esta escala que los materiales pueden adquirir propiedades físicas y químicas diferentes a las que tienen en la escala macroscópica (Ivask et al., 2014; Tortella et al., 2020), como propiedades ópticas, electrónicas, antimicrobianas, magnéticas y catalíticas (Capek, 2006). Debido a estas características la producción global de las nanopartículas (NPs) continúa aumentando, y se han utilizado en numerosos productos comerciales con diversas aplicaciones industriales (Sharma et al., 2019; Tortella et al., 2020). Se han utilizado en el área agrícola, como fertilizantes y pesticidas (Madbouly et al., 2017), en el área médica (Her et al., 2017), principalmente con el desarrollo de NPs para la liberación controlada de fármacos (Pang et al., 2019), en el desarrollo de dispositivos de diagnóstico médico (McNamara & Tofail, 2015),
además, de su uso para mejorar las imágenes médicas (Ryan et al., 2019). Asimismo, las NPs se han utilizado en dispositivos electrónicos (Khanra et al., 2018), en cosméticos (de la Calle et al., 2017), en la nanoremediación (Moustafa, 2017), en el sector agroalimentario (Dasgupta et al., 2017), entre otros.

These particles and molecular structures have dimensions in the nanometric range (typically between 1 and 100 nm in at least one dimension) (Hobson, 2011). It is due to this scale that materials can acquire physical and chemical properties different from those they have on the macroscopic scale (Ivask et al., 2014; Tortella et al., 2020), such as optical, electronic, antimicrobial, magnetic and catalytic properties.

Due to these characteristics, the global production of nanoparticles (NPs) continues to increase, and they have been used in numerous commercial products with various industrial applications (Sharma et al., 2019; Tortella et al., 2020). They have been used in the agricultural area, as fertilizers and pesticides (Madbouly et al., 2017), in the medical area (Her et al., 2017), mainly with the development of NPs for the controlled release of drugs (Pang et al. ., 2019), in the development of medical diagnostic devices (McNamara & Tofail, 2015), in addition to their use to improve medical images (Ryan et al., 2019). Likewise, NPs have been used in electronic devices (Khanra et al., 2018), in cosmetics (de la Calle et al., 2017), in nanoremediation (Moustafa, 2017), in the agri-food sector (Dasgupta et al. , 2017), between
