Conductimetric sensor for atrazine detection based on molecularly imprinted polymer membranes

Potentiometric sensor based on molecularly imprinted polymer for determination of melamine in milk

“…Various chemical sensors have been prepared using MIPs for molecular recognition followed by appropriate signal transductions including capacitance [13], conductometry [14], amperometry [15], voltammetry [16], quartz microbalance [17] and spectroscopy [18]. Potentiometric sensors are generic and highly successful approaches to chemical sensing, and MIP based potentiometric sensors have shown to be very promising [19].…”

New Materials in Electochemical Sensors for Pesticides Monitoring

“…Amperometric sensors have continued to be the most popular largely due to their simplity, ease of production and the low cost of the devices and instruments. Other electrochemical transduction methods for obtaining a signal indicating the rebinding of nonelectroactive substances are based on the change of the permeability of MIP membrane as a consequence of the recombination of the nonelectroactive substance , obtaining conductivity sensors as reported for instance by (Sergeyeva et al, 1999b). An interesting approach for the amperometric detection of the rebound analyte consists on the use of molecularly imprinted conducting polymers.…”

Detection of Oxidative Stress Biomarkers Using Novel Nanostructured Biosensors

“…The templated polymers show recognition properties resembling those found in biological receptors but they are more stable and considerably less expensive than biological systems (Malitesta et al, 2006). A range of molecularly-imprinted polymer-based sensors have been investigated using different transduction techniques, including: acoustic wave , Kugimiya et al, 1999, Liang et al, 2000, Matsuguchi et al, 2006, Percival et al, 2001, Yilmaz et al, 1999, potentiometry (Javanbakht et al, 2008), capacitance , conductometry (Kriz et al, 1996, Sergeyeva et al, 1999, voltammetry (Prasad et al, 2005), colorimetry (Stephenson et al, 2007), surface plasmon spectroscopy (Tokareva et al, www.intechopen.com 2006), and fluorescence (Chen et al, 2004, Jenkins et al, 2001, MorenoBondi et al, 2003 detection. Moreover, the molecularly-imprinted polymers can also be utilized for selective solid-phase separation techniques (Mahony et al, 2005, Masque et al, 2001, including electrophoresis and chromatography.…”
