Novel porous iron phthalocyanine based metal–organic framework electrochemical sensor for sensitive vanillin detection

“…[14][15][16] MOFs, which have the advantages of large specic surface areas, high porosities, and adjustable pore sizes, have been widely studied in elds such as energy storage, gas storage and separation, catalysis, and sensors. [16][17][18][19][20] The advantageous characteristics of MOFs combined with the simplicity, low cost, and high sensitivity of electrochemical sensors has made the development of MOF-based electrochemical sensors of particular recent interest. [21][22][23][24] Phthalocyanine, one of the most investigated functional organic materials, has a two-dimensional conjugated macrocyclic structure with 18p electrons that is composed of four isoindole rings connected by nitrogen atoms.…”

Electrochemical sensor for determination of hydroxylamine using functionalized Fe3O4 nanoparticles and graphene oxide modified screen-printed electrode

“…However, many analytes exhibit irreversible oxidation requiring large overpotential at conventional electrodes [6][7][8][9][10]. Therefore, the use of chemically modified electrodes for the analysis of metals and organics is a well-established practice [11][12][13][14].…”

Electrochemical determination of tramadol using modified screen printed electrode

“…Compared to mentioned methods, electroanalytical methods are more advantageous in terms of higher sensitivity, lower equipment costs and simplicity. Numerous electrochemical methods are mentioned in the literature for analyte determination, with and without the use of modified electrodes [9][10][11][12][13][14][15].…”
