Synergetic Peroxidase-Mimic Catalytic Activity of Noble-Metal-Decorated Lithium Niobate Nanozymes for Potential Biological Applications

Abstract: In this paper, we report a simple, facile, and efficient method to obtain LiNbO3/Au and LiNbO3/Pt nanoparticles composed of LiNbO3 NPs (LN NPs) (30 nm) and ultrasmall nanoparticles (<5 nm, seeds) of Au and Pt, respectively. The synthesis of the nanocomposites followed a simple layer-by-layer method introducing branched poly­(ethyleneimine) (BPEI) as a linker. By varying the volume of metal seeds dispersion added to the LN coated with BPEI, the loading of metal on the surface of the LN is controlled. The morpho… Show more

“…18 Numerous nanomaterials, including CuS NPs, CeO 2 NPs, MoS 2 nanosheets, graphene oxide, Prussian blue nanomaterials, and metal–organic frameworks, such as MIL-101 Fe( ii ), CeO 2 –MIL(Fe), and noble metal nanoparticles, Fe–N–C, and f-MNC, have been discovered recently. 19–28 Researchers have focused on carbon dots (CDs) as nanozymes that exhibit outstanding peroxidase-like activity and have gained considerable attention because of their low toxicity, good optical qualities, good biocompatibility, easy preparation method, and cost-effectiveness. In addition, CDs are easily synthesized using less toxic chemicals, green sources, and waste materials.…”
