“…Th e imprinted nanomaterials have also better dispersibility in analyte solutions and thus greatly reduce the resistance of mass transfer, exhibiting a fast binding kinetics [11]. In particular, novel nanostructure assembly technologies have achieved a wide success in building various nanodevices [12,13]. Th e imprinted nanomaterials with well-defi ned morphologies can feasibly been installed onto the surface of devices in a required form for many applications in nanosensors and molecular detection.…”

Th e molecular imprinting technology provides a distinctive prospect for the creation of three-dimensional cavities, which mimic biological recognition. Over the last decade, substantial eff ort has been devoted from the micro to nanoscale to develop variety of polymeric formats that are compatible with molecular imprinting technology with the aim of emerging a variety of novel synthetic receptors. Th is advancement has off ered considerable advantages, such as greater surfaceto-volume ratio, accessibility to the maximum number of recognition sites, lower diff usion times to facilitate greater uptake and release of the template and overall improved effi ciency. In addition to these, there are also benefi ts related to the distinct diff erences in properties (optical, electrical, mechanical, etc.) demonstrated by nanomaterials when compared with their macroscopic counterparts. In response to this, a new generation of molecularly imprinted synthetic receptors has arisen over the past decade that display physical properties, which are oft en closer to those demonstrated by enzymes and antibodies, such as physical size, solubility, fl exibility and recognition site accessibility. In this chapter, we like to focus on the recent development in the fi eld of craft ing recognition sites on nanostructured materials and/or designing imprinted materials at nanoscale and their consequences for the common mankind.

“…On the basis of the type of binding event occurring on the transducer, MIP-based sensors can be categorized as electrochemical, optical, or piezoelectric [32,[78][79][80][81]. Further subdivision is possible where affinity sensors can be classed either as immunosensors (or receptor-type sensors) or as catalytic sensors.…”

“…Potentiometric sensors, a subgroup of chemical sensors, are attractive for practical applications, as they are associated with small size, portability and low energy consumption and cost compared to other group of sensors. The development of MIP based sensors with potentiometric transduction does not require the template or print molecule to be extracted from the membrane to create membrane potential and does not have to diffuse through the membrane, so that there is no size restriction on the template molecule, the main achilles heel of MIP's until recently [16][17][18]. Zhou, et al [19] reported for the first time MIP based potentiometric sensor for methylphosphonic acid, an ultimate degradation product of nerve agents by coupling surface imprinting technique with a nanoscale transducer, indium tinoxide.…”

Biomimetic potentiometric sensor for the determination of diethyl chlorophosphate was developed using imprinted polymer inclusion membrane strategy. Semi-covalent imprinted and non-imprinted polymer particles were synthesized and found that non-imprinted polymer inclusion membrane was unstable in contrast to imprinted polymer inclusion membrane in determination and quantification of diethyl chlorophosphate. Imprinted polymer inclusion membrane based sensor found to be pH dependant with a 5 min equilibrium response time at pH = 10.5 and linearly responds to diethyl chlorophosphate in the concentration range of 1 × 10 -9 to 1 × 10 -4 and 1 × 10 -4 to 1 × 10 -2 mol·L -1 with a detection limit of 1 × 10 -9 mol·L -1 (0.17 ppb). It was found that diethyl chlorophosphate response was selective against various selected interferents like pinacolyl methylphosphonate, dimethyl methyl phosphonate, methylphosphonic acid, Phorate and 2, 4-D. The developed sensor was found to be stable for 3 months and can be reusable more than 30 times without loosing sensitivity. The developed sensor was successfully applied for the determination of diethyl chlorophosphate in natural waters.
