Magnesium oxide nanoparticles (MgONPs) synthesized by efficient green approach have unique physiochemical properties. In this study, MgONPs are synthesized with bract extract of Musa acuminate, an agro waste. The surface plasmon resonance at 450 nm in UV spectrum and FTIR peaks at 601 and 890 cm−1 confirmed the presence of MgONPs. XRD pattern revealed high crystallinity of the nanoparticles with an intense orientation peak at 111, and the size was 13 nm. The particles were spherical with an average size of 24.85 nm. The elemental percentage of magnesium and oxygen were 68.55% and 31.45%. MgONPs had antibacterial activity against Bacillus subtilis, Escherichia coli, Vibrio harveyi, Vibrio parahemolyticus, and Staphylococcus aureus with MIC, 6 μg/mL. The IC50 value for MCF‐7 cell was 113.56 μg/mL, and the normal cell line was 785.69 μg/mL. The NPs also exhibited hemolytic features in a dose‐dependent manner. The MgONPs exhibited photocatalytic degradation of methyl violet, CBB G‐250, and malachite green in 60 min duration. MgONPs had promising antibacterial, cytotoxic, hemolytic, photocatalytic, and seed germination activity. They have the potential to serve as an additive in a variety of biological applications.

“…Successful removal of phenol red using iron nanoparticles prepared from tea waste was reported (Gautam et al, 2018). Similarly, successful removal of methylene blue dye using manganese oxide nanoparticles synthesized using tea extracts was reported (Kumar et al, 2022). Recently, novel heterostructure ZnFe 2 O 4 nanosphere-decorated α-NiMoO 4 nanorods and coffee biochar were successfully synthesized by a hydrothermal method and showed promising removal of ketoprofen (Kumar Ray et al, 2023).…”

The introduction of large amounts of pharmaceuticals into the environmental waters is well‐documented in literature with their occurrence reported in all different water matrices accessible to humans and animals. At the same time, the increasing consumption of coffee and tea‐based beverages results in the generation of solid waste, which is mostly disposed‐off in the environment. To minimize environmental pollution, coffee and tea‐based materials have been proposed as suitable options to remove pharmaceuticals in environmental waters. Therefore, this article provides a critical review on the preparation and applications of coffee and tea‐based materials in removing pharmaceuticals from contaminated water. In this context, most studies in literature focused on the applications of these materials as adsorbents, while only limited work on their role in degradation of pharmaceuticals is discussed. The successful application in adsorption studies is attributed to high surface areas of adsorbents and the ability to easily modify the adsorbent surfaces by incorporating functional groups that provide additional oxygen atoms, which promote easy interactions with pharmaceuticals. Hence, the adsorption mechanisms are mostly described by hydrogen bonding, electrostatic and π–π interactions with sample pH playing a dominant role in the adsorption process. Overall, the present article focused on the developments, trends and future research direction on the preparations and applications of coffee and tea‐based materials for efficient removal of pharmaceuticals in water. Practitioner Points Review of tea and coffee wastes application for removal of pharmaceuticals in water Key applications in adsorption and degradation of pharmaceuticals in water Removal mostly explained by hydrogen bonding, electrostatic, and π–π interactions Trends, gaps, and future research to be explored are reviewed and highlighted

The unique biological and physicochemical characteristics of biogenic (green-synthesized) nanomaterials (NMs) have attracted significant interest in different fields, with applications in the agrochemical, food, medication delivery, cosmetics, cellular imaging, and biomedical industries. To synthesize biogenic nanomaterials, green synthesis techniques use microorganisms, plant extracts, or proteins as bio-capping and bio-reducing agents and their role as bio-nanofactories for material synthesis at the nanoscale size. Green chemistry is environmentally benign, biocompatible, nontoxic, and economically effective. By taking into account the findings from recent investigations, we shed light on the most recent developments in the green synthesis of nanomaterials using different types of microbes and plants. Additionally, we cover different applications of green-synthesized nanomaterials in the food and textile industries, water treatment, and biomedical applications. Furthermore, we discuss the future perspectives of the green synthesis of nanomaterials to advance their production and applications.
