Article Synopsis
- - The title compound features a nickel (Ni) atom that is coordinated by two tridentate ligands, resulting in a distorted octahedral structure.
- - The crystal exhibits monoclinic symmetry at 100 K and includes a mixture of water and methanol as part of its structure.
- - One ethyl group in the ligands shows disorder between two positions, and there are notable hydrogen bonds between the solvent molecules and the ligand groups.
A new series of alkaline earthides based on Cryptand [2.2.2] (C222) containing nine complexes is designed by carefully placing alkali metals and alkaline earth metals inside and outside the C222 complexant, respectively M1(C222)M2 (M1 = Li, Na, K; M2 = Be, Mg, Ca).

The chitosan (CS) modification on the nanocomposite layer allowed glutaraldehyde (GLUT) cross-linking, resulting in the immobilization of ApoA1 aptamers. Scanning electron microscopy, tunneling electron microscopy, and energy dispersive X-ray spectroscopy were used to characterize the nanocomposite, while electrochemiluminescence (ECL), cyclic voltammetry, and electrochemical impedance spectroscopy were used to analyze the aptasensor assembly.

Each layer of the interface was characterised using field emission-scanning electron microscopy (FE-SEM) and cyclic voltammetry (CV). The fabricated SPE/AuMRs/PdNPs/PANI interface demonstrated the highest electronic current and showed excellent peroxidase-mimic towards HO using chronoamperometry (CA).

- - This study introduces a new electrochemiluminescence method for precisely measuring creatine kinase MB (CK-MB) using a special nanocomposite made from carbon nano-onions and metal nanoparticles like gold and iron oxide.
- - The immunosensor was created by layering the nanocomposite on an electrode, attaching an antibody, and using a specific luminophore and co-reactant for optimal light emission during testing.
- - It demonstrated an impressive detection range from 50 fg/mL to 10 ng/mL with a very low detection limit of 5 fg/mL, along with excellent selectivity and stability for potential clinical application in human serum samples.
