Caracterización de nanopartículas de plata sintetizadas por vía verde
Resumen
En esta investigación se desarrolló síntesis verde de nanopartículas de plata (AgNPs) utilizando el extracto de Thuja orientalis. Se caracterizaron las nanopartículas mediante: espectroscopía UV-Vis, espectroscopía infrarroja por Transformada de Fourier (FTIR), tamaño de partícula por DLS y potencial zeta. La espectrometría UV-Vis reveló la formación de un plasmón de resonancia superficial (PRS) cerca de los 420 nm característico de la presencia de AgNPs. El espectro de FTIR mostró los grupos funcionales característicos de las fitomoléculas tales como R—O—H (3,335), O=C-OH (2314), C-C=C (1,450). El potencial zeta evidenció el tamaño y la luz electroforética la estabilidad de las NPs mostrando valores de 86.82 nm y -19.6 mV respectivamente. Estos resultados demostraron que la infusión de Thuja orientalis es un reductor eficiente en la síntesis de partículas con tamaño nanométrico.
