Biological Evolution of New Intercalated Layered Double Hydroxides: Anticancer, Antibacterial and Photocatalytic Studies

Abstract

In this work, we have synthesized a novel sodium‐3‐nitrobenzenesulfonate (SNBS) of organic moiety intercalated into Zn−Al layered double hydroxide nanoflakes (ZANF) via facile hydrothermal method. The structure, optical property, morphology, size and surface area of the as‐synthesized intercalated Zn−Al nanoflakes (i‐ZANF) were characterized by various techniques. The i‐ZANF was utilized as an anti‐cancer agent against MCF‐7 cell lines. The IC50 value of synthesized i‐ZANF against MCF‐7 cancer cell was found to be 30 μg/mL. Antibacterial activity against noxious bacteria such as, methicillin resistant staphylococcus areus and Acinetobacter baumannii has been examined. Photocatalytic activity of i‐ZANF was evaluated by using methylene blue (MB) as a toxic environmental pollutant. The obtained results showed that the i‐ZANF has notable antibacterial and anticancer activity, along with excellent photocatalytic degradation efficiency (91.2% within 105 min). Hence, it can be proposed that the i‐ZANF with multifunctional applications has been developed to expand as large potential window for anticancer agents, antibaterial and photocatalytic field in upcoming days.

Rationally Designed Ag@polymer@2-D LDH Nanoflakes for Bifunctional Efficient Electrochemical Sensing of 4-Nitrophenol and Water Oxidation Reaction

“…Layered double hydroxides (LDHs) have been widely studied owing to their exotic layered structure in several important fields such as cancer therapy, dye degradation, supercapacitors, and biomolecule sensors. − Fe-, Co-, and Ni-based LDH materials have been recognized as an emerging family of efficient electrocatalysts for OER in alkaline media because of the adsorption behavior due to the well-optimized M–O bond strength (OER intermediates, e.g., M–OH, M–O, M–OOH, and M–OO). − Ni and its oxides/hydroxides have been explored on the formation of metal oxyhydroxides step as a crucial factor during OER . After that, LDH-based materials have been made to attempt to create an efficient durable OER electrocatalysts with effective bifunctional properties .…”
