The utilization of ultrathin Mn-metal−organic framework (Mn-UMOF) nanosheets for oxidase-like nanozyme activity has been demonstrated. The Mn-UMOF exhibited superior nanozyme activity to oxidize chromogenic TMB and ABTS than the bulk Mn-BMOF. Based on this fact, a platform for the colorimetric sensing of L-cysteine (L-cys) has been established over...

In this study, the strain induced modification in Au-Ag bimetallic nanoparticles (BNPs) coated on silica rich activated sand has been investigated. The coating of BNPs on activated sand modifies the interface as well as induces microstrain in the structure of the BNPs. The detailed investigation of the interfacial interaction of BNPs with silica in...

Carbon dots with peroxidase mimicking properties have attracted considerable attention for various sensing and biomedical applications. However, most peroxidase nanozymes do not show activity at neutral pH and only work in acidic conditions. In this work, crystalline Cu‐doped, Mn‐doped, and undoped carbon dots (CDs) are prepared via one‐step, solid...

s Graphene oxide nanocomposites in polyethylene glycol (GO-PEG) were prepared by the ultrasonication assisted suspension. GO was synthesized by the modified Hummer’s method and was then dispersed in PEG to obtain the nanocomposites. The sonication time for the synthesis of the nanocomposites was varied to study its effect on the structural, optical...

This work reports the synthesis of Au doped iron oxide nanoparticles by co-precipitation method using a cationic polymer as a stabilizer and subsequent coating with graphene oxide (GO) to form the catalytically enhanced GO/Au-Fe3O4 nanoparticles. The nanoparticles were characterized using Fourier Transform Infrared (FT-IR) spectroscopy and X-ray di...

Gold-Silver (Au-Ag) bimetallic alloy nanoparticles exhibit improved catalytic activity in comparison to the monometallic nanoparticles due to synergistic effect. In this work Au-Ag bimetallic alloy nanoparticles (BNPs) have been supported on alkali activated sand which acts as an inert support material, stabilizes the nanoparticles and prevents the...

In this work, Boron Nitride (BN) nano-particles have been synthesized by hydrothermal treatment using boric acid and an amine-based nitrogen source. BN, a structural analogue of carbon, has garnered considerable attention in the recent years due to its high thermal conductivity, chemical stability, low toxicity, large intrinsic band gap and chemica...
