ZnO nanoparticles impregnated with Hibiscus sabdariffa L. extract: Characterization and antimicrobial activity.
ABSTRACT Zinc oxide can be a vehicle for the encapsulation of bioactive compounds obtained from Hibiscus sabdaridffa L by-products due to its mesoporous structure. The nanoparticles obtained with zinc nitrate showed an average particle size of 120 mn, when impregnated with ultrasound-assisted extract of Jamaican by-product did not show morphological alterations, however; it was observed that there is a modification of the ZnO energy bands attributed to the interactions between ZnO and the extract molecules. T1.0 % and T1.5 % presented higher inhibition on Listeria Monocytogenes, Staphylococcus aureus, Escherichia coli, and Staphylococcus mutans compared to T0.5 % and EUSJ. The results show that the synthesis process and the impregnation of Jamaican by-product extracts have interesting antibacterial properties associated with the potentiating effect of ZnO and extract, which can be a starting point for further studies on some applications or other types of microorganisms.
