Summary: Molecularly imprinted polymer (MIP) is a synthetic material that mimics the natural antibody-antigen system and is suitable for use in electrochemical sensors. However, the irregular shape and slow electron transfer rate of MIP limit the sensitivity and conductivity of the sensors. The integration of nanomaterials improves the sensing and recognition capability of MIP sensors.

Summary: A new metal complex was synthesized by metallating a metal-free porphyrazine derivative with nickel(II) ions. The purity of the complex was confirmed using various analytical techniques. The complex was combined with different carbon nanomaterials to create hybrid electroactive electrode materials. The electrocatalytic properties of the complex on various carbon nanostructures were extensively studied, and a modified electrode using MWCNTs showed the best electrocatalytic properties for hydrogen peroxide oxidation/reduction. The prepared sensor showed a linear response to H2O2 and could be potentially used in biomedical and environmental applications.
