dc.description.abstract | La radiación solar, principalmente, los rayos UVA y UVB son una de las principales causas de cáncer en la piel, comúnmente, las cremas con protección solar usan moléculas inorgánicas como el TiO2, sin embargo, por su actividad fotocatalítica muestra producción de especies reactivas de hidrogeno (ROS), lo cual puede producir daños en la piel. En este trabajo se planteó estudiar el rendimiento de las nanopartículas de TiO2 en términos de su toxicidad in vitro, siendo sintetizada para aumentar la pureza del compuesto, para establecer una morfología y un tamaño similar al usado dermatológicamente. Para este fin, las partículas de TiO2 se sintetizaron por un método hidrotérmico, caracterizado por microscopía electrónica de barrido (SEM) y espectroscopía de difracción de rayos X (EDS), donde se verificó la pureza de las nanopartículas y su aspecto morfológico. Se realizó un análisis microbiológico in vitro para establecer la actividad antimicrobiana de las nanopartículas de TiO2 sobre Serratia marcescens y Escherichia coli. | spa |

dc.description.abstractenglish | Solar radiation, mainly, UVA and UVB rays are one of the main causes of cancer in the skin, sunscreen creams commonly use inorganic molecules such as TiO2, however, due to their photocatalytic activity shows production of reactive species of hydrogen (ROS), which can cause skin damage. In this work, it was proposed to study the performance of TiO2 nanoparticles in terms of their in vitro toxicity, being synthesized to increase the purity of the compound, to establish a morphology and size similar to that used dermatologically. For this purpose, the TiO2 particles were synthesized by a hydrothermal method, characterized by scanning electron microscopy (SEM) and X-ray diffraction spectroscopy (EDS), where the purity of the nanoparticles and their morphological appearance were verified. An in vitro microbiological analysis was carried out to establish the antimicrobial activity of the TiO2 nanoparticles on Serratia marcescens and Escherichia coli. | spa |
