An electrochemiluminescence sensor with dual signal amplification of Ru(bpy)32+based on PtNPs and glucose dehydrogenase for diagnosis of gas gangrene

Gas gangrene is a bacterial infection that produces gas in tissues in gangrene.C. perfringenswith alpha-toxin plays a key role in gas gangrene. Detection ofC. perfringensis highly important in clinical diagnosis of gas gangrene.

Understanding the binding interaction of imidazole with ZnO nanomaterials and clusters

The order of binding energy values for imidazole adsorbed ZnO clusters through the preferred azomethine nitrogen site is imidazole–Zn₄O₄ (R) > imidazole–Zn₃O₃ > imidazole–Zn₄O₄ (W) > imidazole–Zn₂O₂.

Thermodynamically feasible photoelectron transfer from bioactive π-expanded imidazole luminophores to ZnO nanocrystals

The chemical affinity between the nitrogen atom of the imidazole and the zinc ion on the surface of the nano oxide may be a reason for strong interaction of the ligand on nanoparticles causing the enhancement.

Enhancing photoluminescent behavior of 2-(naphthalen-1-yl)-1,4,5-triphenyl-1H-imidazole by ZnO and Bi2O3

A fluorophore 2-(naphthalen-1-yl)-1,4,5-triphenyl-1H-imidazole [NTI] has been designed, synthesized and characterized by (1)H NMR, (13)C NMR, mass and single crystal XRD. Absorption, emission, lifetime and cyclic voltammetry have been made to deduce the interaction between NTI and ZnO and Bi2O3 nanocrystals. NTI act as a new host for ZnO and Bi2O3 nanocrystals that enhance its luminescence. The apparent binding constant has been obtained. Adsorption of the NTI on ZnO and Bi2O3 nanocrystals lowers the HOMO energy level of the NTI. The strong adsorption of the NTI on the surface of ZnO and Bi2O3 nanocrystals is likely due to the chemical affinity of the nitrogen atom of the NTI to the zinc ion on the surface of nanocrystals. SEM and EDS spectra confirmed the adsorption of NTI on the surface of nanocrystals.
