An electrochemical sensor based on Ce-MOF-derived Ce-doped poly(3,4-ethylenedioxythiophene) composite for efficient determination of rutin in food

A novel electrochemical sensor based on a molecularly imprinted polymer for highly selective and sensitive determination of rutin from herbal supplements and plant extracts

“…12 The effect of RUT on the increase in high-density lipoprotein (HDL) cholesterol and triacylglycerol levels in hyperlipidemic rats was investigated, and it was determined that RUT caused the maximum decrease in the cholesterol level. 14 When a literature review was conducted on the studies performed for RUT analysis, it was seen that the available studies are based on electrochemical nanosensors, [15][16][17][18][19][20][21][22][23][24][25][26][27] capillary electrophoresis, 28 electrochemiluminescence, 29 high-performance liquid chromatography (HPLC) with an ultraviolet (UV) detector, 8,30 HPLC with a diode array detector, 31 HPLC with chemiluminescence (CL) detection, 32 and molecularly imprinted polymer (MIP)-based electrochemical sensors. [33][34][35][36] Although the mentioned studies offer advantages such as high sensitivity for RUT determination, the most important challenges of chromatographic methods are that they require highly skilled operators, expensive equipment, and labor-intensive procedures.…”

An efficient electrochemical sensor based on the Ce-MOF/g-C3N5 composite for the detection of nitrofurazone

“…Electrochemical sensing, which is a method of detecting substances using electrochemical principles, is highly sensitive, selective, fast and costeffective for directly measuring the concentration of nitrofurazone in aqueous solutions without complicated pretreatment and separation steps. [11][12][13] However, electrochemical sensors face some challenges owing to the adsorption and oxidation of nitrofurazone on the electrode surface, such as low detection sensitivity and a narrow linear range, in the process of detecting nitrofurazone. These ndings indicate that there is an urgent need to study sensors based on high-performance electrocatalysts for the analytical detection of nitrofurazone.…”

Detection of Ascorbic Acid by Two-Dimensional Conductive Metal-Organic Framework-Based Electrochemical Sensors

“…Metal-organic frameworks (MOFs), as a novel porous material, have attracted extensive attention in the fields of catalysis [ 17 ], separation [ 18 ], energy storage [ 19 ], and drug delivery [ 20 ] due to their high porosity, large surface area, and structural diversity. Recently, MOFs have also been used for electrocatalytic sensing, but their inherent low conductivity severely affects the efficiency of charge transport, so they need to be combined with other conductive materials to improve their electrochemical performance [ 21 , 22 ]. However, composite materials will reduce the specific surface area and stability of the MOF, and the composite interface is difficult to accurately control.…”
