In-situ and controllable synthesis of graphene-gold nanoparticles/molecularly imprinted polymers composite modified electrode for sensitive and selective rutin detection

Gold Nanomaterials-Based Electrochemical Sensors and Biosensors for Phenolic Antioxidants Detection: Recent Advances

“…The number of examples using a molecularly imprinted polymer as the key recognition element was comparable to that of the enzyme-based sensors [ 115 , 122 , 123 , 124 , 173 , 174 , 186 , 191 , 193 , 196 ], indicating that it could represent a promising synthetic receptor to be used instead of a “classical” enzyme.…”

“…Several examples introduced screen-printed carbon electrodes, modified with different gold nanomaterials [ 75 , 84 , 85 , 88 , 89 , 93 , 109 , 114 , 115 , 147 , 148 , 161 , 172 , 173 , 186 ].…”

“…A composite involving G, AuNPs, and MIP was prepared and used to modify SPCE, to develop an RT electrochemical sensor [ 173 ]. The G/AuNPs composite was synthesized by the simultaneous electrochemical reduction of GO and the AuNPs precursor at SPCE.…”

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

“…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. Chromatographic methods have disadvantages such as high cost, complex processing procedures, need for expert personnel and difficulties in the sample preparation phase.…”
