Resumo: Bacterial resistance is one of the biggest global health challenges, impacting around 700.000 deaths per year, in addition to dramatic consequences in the hospital and social spheres. Although it is a growing and highly threatening problem, the number of effective drugs available to combat these superbugs is increasingly limited, making the importance of the search for new options for antibiotic therapy emphatic. This study aimed to produce silver nanoparticles stabilized in hydroalcoholic extract of mastruz; to characterize them through of Visible Ultraviolet (UV- Vis); evaluate the stability of silver nanoparticles after 48h and 72h; characterize the hydroalcoholic extract of mastruz through spectrophotometric study and analyze the bactericidal potential of silver nanoparticles. Silver nanoparticles were developed through green synthesis, later characterized by Spectrophotometric Visible Ultraviolet (UV- Vis) and applied to cultures of Gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa e Klebsiella pneumoniae) and Gram positive (Staphylococcus aureus). The nanoparticles were produced through green synthesis, showed a maximum absorption peak of 400 nm in the spectrophotometric study, and they remained stable after 48h and 72h. The hydroalcoholic extract of mastruz showed two peaks of maximum absorption (332 nm and 674 nm) in the spectrophotometric analysis. Also, the bactericidal activity of the silver nanoparticles was observed, through the presence of inhibition halos of approximately 14 mm in the tested cultures.

Aunque es un problema creciente y altamente amenazante, la cantidad de medicamentos efectivos disponibles para combatir estas superbacterias es cada vez más limitada, lo que enfatiza la importancia de buscar nuevas opciones para la terapia con antibióticos. Este estudio tuvo como objetivo producir nanopartículas de plata estabilizadas en extracto hidroalcohólico de mastruz; caracterizarlos a través del Ultravioleta Visible (UV-Vis); evaluar la estabilidad de las nanopartículas de plata a las 48h y 72h, caracterizar el extracto hidroalcohólico de mastruz mediante el estudio espectrofotométrico y analizar el potencial bactericida de las nanopartículas de plata. Las nanopartículas de plata fueron desarrolladas a través de síntesis verde, posteriormente caracterizadas por Análisis Ultravioleta Visible (UV-Vis) y aplicadas a cultivos de bacterias Gram negativas (Escherichia coli, Pseudomonas aeruginosa y Klebsiella pneumoniae) y Gram positivas (Staphylococcus aureus). Las nanopartículas fueron producidas a través de la síntesis verde, mostraron un pico máximo de absorción de 400 nm en el estudio espectrofotométrico y se mantuvieron estables a las 48h y 72h de la síntesis. El extracto hidroalcohólico de mastruz mostró dos picos de máxima absorción (332 nm y 674 nm) en el análisis espectrofotométrico. También se observó la actividad bactericida de las nanopartículas de plata, mediante la presencia de halos de inhibición de aproximadamente 14 mm en los cultivos ensayados.A resistência bacteriana é um dos maiores desafios da saúde global, impactando cerca de 700. 000 mortes por ano, além de consequências dramáticas em âmbito hospitalar e social.
