    Two bionanocomposites based on suture threads, silk-silver nanoparticles (Ag NPs) and catgut-Ag NPs, were prepared through a green chemistry methodology using Chenopodium ambrosioides (Mexican Epazote) as reducing agent. UV-Vis spectrophotometry (UV-Vis), Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM), were used for their characterization. UV-Vis confirmed the synthesis of silver nanoparticles. Micrographs showed polydisperse, mostly spherical, Ag NPs attached to both suture threads. The bionanocomposites antimicrobial properties were evaluated through cultures and inhibition zones tests. The Chenopodium ambrosioides-assisted synthesized bionanocomposites have proved antibacterial effect against S. aureus and E. coli in both sutures (silk and catgut) and could be potentially useful for oral or periodontal surgery. There was no significant difference statistically in inhibition of Staphylococcus aureus versus Escherichia coli

    Green Synthesis of Silver Nanoparticles Using <em>Heterotheca inuloides</em> and Its Antimicrobial Activity in Catgut Suture Threads

    Silver nanoparticles were synthesized through a green method, using Heterotheca inuloides as a bioreducing agent. Moreover, catgut suture threads were decorated with those biogenic silver nanoparticles, and their antibacterial activity versus highly resistant pathogenic microorganisms was evaluated. The principles of green chemistry and nanotechnology allow us to obtain advanced materials, such as suture threads, which can reduce or avoid the prevalence of infectious processes in the medical field. Mexican medicinal plants, such as H. inuloides, represent an adequate alternative for biosynthesis; this plant species is known for its medicinal benefits and its antibacterial activity, and for that reason, it is being used in folk medicine

    La ocurrencia de infecciones por la utilización de hilos de sutura a base de fibras naturales, representa en la actualidad, un riesgo evidente a la salud humana, especialmente los hilos de sutura multifilamento, en donde se ha encontrado una acumulación importante de comunidades bacterianas. Además de cuidar los procedimientos durante el acto quirúrgico, y la elección del material adecuado, es importante contar con sustancias o productos que posean un efecto antiséptico, que disminuya el riesgo a contaminación post quirúrgica. Uno de los requisitos más importantes que un material de sutura debe reunir, es el hecho de poseer propiedades físicas, mecánicas, de manejo, biocompatibilidad y efecto antibacteriano. La nanotecnología representa una alternativa para la creación de materiales avanzados que coadyuven a la práctica quirúrgica bucomaxilofacial. El presente trabajo propone la creación de un bionanocomposito que posea un efecto inhibitorio sobre microorganismos patógenos y que sea producido bajo condiciones eco-amigables para aminorar el daño ocasionado a la salud y el impacto ambiental
