Recent Advances in Electrochemical Sensors Based on Molecularly Imprinted Polymers and Nanomaterials

“…Due to their separation and pre‐concentration properties, low toxicity, ease of preparation, and their low‐cost, magnetic nanoparticles (Fe 3 O 4 NPs) are widely used as a support core decorated molecularly imprinted polymers for electrochemical sensing applications .…”

“…The use of magneto‐electrodes for the electrochemical detection of various kinds of compounds was significantly improved as novel sensing strategy. Taking advantage of the ability of magneto electrochemical sensors to capture different functionalized magnetic beads as well as MagMIPs from solution makes it an excellent devise for determination of molecules and biomolecules in recent years . This sensing strategy is based on the impregnation of an external magnet onto the electrochemical sensors, which leads to easy collection of MagMIPs from the solution containing the analyte as indicated in Scheme .…”

“…Indeed, Madrakian et al. have reported a novel magneto sensor based on MWCNTs paste electrodes for the detection of mefenamic acid (MFA). MagMIPs specific for MFA were synthesized and then added to a solution containing a known amount of MFA target analyte.…”

“…Recently, using magneto electrodes in electrochemical by sensing various compounds has been improved. The ability of magneto electrochemical sensors to capture different functionalized magnetic beads from a solution has made these sensors an excellent devise to determine molecules and biomolecules [30][31][32][33].…”

Novel mefenamic acid PVC membrane sensor based on a new Cd Schiff's base complex containing a phenanthroline unit

“…Several analytical methods have already been reported for the determination of mefenamic acid including potentiometric, 5 ow injection analysis, 6 spectrophotometry, [7][8][9][10][11] HPLC method, [12][13][14][15][16] stability-indicating HPTLC determination, 17 different chromatographic methods such as TLC-densitometric, 18 RP-HPLC-DAD method, 19 spectrouorimetry method, 20 titration methods, 21 electrochemical sensors, 22 atomic absorption spectrometry, 23 nuclear magnetic resonance spectroscopy 24 and magneto carbon paste electrode. 25 Electrochemical methods are preferred over optical methods because they are relatively rapid, show high sensitivity and selectivity. Recently, several methods have been used for increase selectivity, sensitivity, detection limit and other property of potentiometric sensors.…”
