Biogenic zinc selenide nanoparticles fabricated using Rosmarinus officinalis leaf extract with potential biological activity.

Zinc selenide nanoparticles (ZnSe) are semiconductor metals of zinc and selenium. ZnSe NPs are advantageous for biomedical and bio-imaging applications due to their low toxicity. ZnSe NPs can be used as a therapeutic agent by synthesizing those using biologically safe methods.

Preparation of Zinc Oxide Nanoparticles Assisted by Okra Mucilage and Evaluation of its Biological Activities.

Background: In this study, zinc oxide nanoparticles (ZnO-NPs) were biologically synthesized from Abelmoschus esculentus L. (Okra) mucilage fraction (OM).

Methods: Analytical techniques were employed to study the formation and properties of OM-ZnO NPs, including their morphology, shape, size distribution, and surface charges.

Bio-inspired silver selenide nano-chalcogens using aqueous extract of Melilotus officinalis with biological activities.

For the first time, an aqueous extract of Melilotus officinalis was used to synthesize bimetallic silver selenide chalcogenide nanostructures (AgSe-NCs). The formation of NCs was confirmed and characterized by UV-visible and FTIR spectroscopy, SEM and TEM imaging, XRD and EDX crystallography, zeta potential (ZP) and size distribution (DLS). The bioactivities of biosynthesized AgSe-NCs, such as antibacterial, antibiofilm, antioxidant and cytotoxicity potentials, were then examined.
