A novel molecularly imprinted sensor for selectively probing imipramine created on ITO electrodes modified by Au nanoparticles

Molecularly imprinted polypyrrole films: Some key parameters for electrochemical picomolar detection of dopamine

“…We found that when the MIP was incubated for 40 min, the current intensity reaches a steady state which indicates that the diffusion of the template molecule towards the recognition sites was complete. For imipramine-imprinted sol-gel films, a plateau value of current intensity peak was obtained after at least 50 min incubation time [46]. For routine analysis, we set the incubation time to 20 min (half time for reaching saturation).…”

Molecularly Imprinted Electrochemical Sensors

“…Immobilization of trans-resveratrol imprinted film on the surface of functionalized ITO electrode was carried out followed by further modifcation with g-methacyloxypropyl triethoxysilane (g-MPS) [73]. In a recent work, SAMs of gold nanoparticles were prepared on ITO electrode via sol-gel technology for imprinting imipramine [74]. Though there are more studies related to sensors containing silanes as the recognition element, their practical applications are very few as the stability of the alkyl chlorosilanes SAMs is found to be smaller than that of the alkanethiols SAMs.…”

“…In another work, an artificial receptor for UA, silica gel-bonded with the same MIP was used as a sorbent for molecularly imprinted solid-phase extraction (MISPE) in column chromatography [54]. Recently, self assembled modification of gold nanoparticles and g-methacycloxypropyl trimethoxy silane on ITO electrode was used for imprinting imipramine [74] and transresveratrol [73] respectively.…”

Differential Pulse Voltammetry Technique for the Determination of Imipramine, Dopamine and Norepinephrine Using a Hydroquinone Derivative Multi-wall Carbon Nano-tube Carbon Paste Electrode

“…Several reports have been found for chromatographic 5 and electrochemical determination of imipramine 6,7 , affinity chromatography-mass spectrometry 8 and electrochemical methods for the determination of dopamine [9][10][11][12] and gas chromatography-mass spectrometr y 13 and electrochemical techniques for quantitative determination of norepinephrine [14][15][16][17] individually and in the presence of other co-existing species.…”
