Palladium Nanoparticle-Decorated Copper-Hemin Metal Organic Framework for Enzymatic Electrochemical Detection of Creatinine in Human Urine.

Creatinine is indeed a crucial biomarker for kidney diseases. In this work, a novel electrochemical biosensor based on a copper-hemin metal organic framework [Cu-hemin metal-organic framework (MOF)] nanoflake decorated with palladium (Pd) (Pd/Cu-hemin MOF) was fabricated and incorporated with creatinine deiminase (CD) on a glassy carbon electrode (GCE) for creatinine detection. The formation of a Pd/Cu-hemin MOF composite was confirmed by X-ray photoelectron spectroscopy, X-ray diffraction, and Fourier transform infrared spectroscopy.

A Sensitive Enzymatic Electrochemical Biosensor for Cholesterol Based on Cobalt Ferrite@Molybdenum Disulfide/Gold Nanoparticles.

Cholesterol is essential in biological systems, and the level of cholesterol in the body of a person acts as a diagnostic marker for a variety of diseases. So, in this work, we fabricated an enzymatic electrochemical biosensor for cholesterol using cobalt ferrite@molybdenum disulfide/gold nanoparticles (CoFeO@MoS/Au). The synthesized composite was used for the determination of cholesterol by voltametric methods.

Synthesis of novel SnZnO-chitosan nanocomposites: Structural, morphological and luminescence properties and investigation of antibacterial properties.

In recent times, metal oxide-organic nanocomposites have received great attention because of their feasibility to wide range applications such as super capacitors, antibacterial activity, biomedical sensors, battery applications and microfluidic devices. In this work, zinc oxide-chitosan (ZnO-CS) and their novel tin zinc oxide-chitosan (SnZnO-CS) hybrid nanocomposites successfully synthesized by a simple one-pot sol-gel reaction. The equal metal oxide ratio such as 0.
