New bimetallic porphyrin film

Electrocatalytic Reduction of Hydrogen Peroxide by Nanostructured Bimetallic Films of Metalloporphyrins

“…These devices showed a significantly high peroxidase activity at À 200 mV vs. Ag/AgCl, [10,11] which was in line with the synergistic catalytic effect observed in hetero-bimetallic systems [12].…”

“…In previous reports we pointed out that peroxidase activity of polyFePP modified electrode, at low electrode potentials, was only achieved with exhaustive removal of oxygen [10]. Whereas, in the same publication, we demonstrated that polyCuPP deposited on polyFePP presents an important catalytic activity at À 200 mV vs. Ag/AgCl over a wide pH range.…”

Protein Based Electrochemical Biosensors for H2O2 Detection Towards Clinical Diagnostics

“…Hence, the research on H 2 O 2 detection is mainly focused on electrode modifications in order to decrease the overpotential and increase the electron transfer kinetics. Towards this, several types of nano‐biomaterials such as redox proteins 22, transition metals 23, metal oxides 24, metal porphyrin 25, redox polymers 26, and carbon nanotubes 27 have been employed to perform electrocatalytic H 2 O 2 detection. Furthermore, the size and structure of biomaterials (proteins) can be tailored for designing a novel sensing platform and enhancing sensing performance 28.…”

A novel competitive capacitive glucose biosensor based on concanavalin A-labeled nanogold colloids assembled on a polytyramine-modified gold electrode

“…Consequently, to improve the biosensor performance, suitable immobilization methods must be explored. Electropolymerization, as a promising approach to prepare immobilization matrices for biosensors, has received attention in recent years [28,29]. Unlike the conventional strategies for immobilization, electropolymerization has no limitations in terms of the geometry and area of the electrode, and offers advantages with respect to thickness control and uniformity of the polymer film on electrode surfaces with more complex geometries [30].…”
