“…Therefore, the prepolymerization mix is put on the sensor surface by spin or spray coating or just by dropping or spreading the mix over the sensor surface. Polymerization of the final MIP can then be realized using UV, thermal or electro polymerization (Belmont et al, 2007;Bunte et al, 2007;Delaney et al, 2007;Fang et al, 2009a;GomezCaballero et al, 2008;Pardieu et al, 2009;Suedee et al, 2006a,b;Ulyanova et al, 2006;Wu et al, 2009;Yang and Zhang, 2009;Zhang et al, 2008). Coating with PVC is also frequently used to immobilize MIPs on a sensor surface.…”

“…Plasmon resonance spectroscopy was used for theophylline determination in solution (Lavine et al, 2007). A first example of reflectance technology in combination with molecular imprinting films is given by Wu et al (2009) for the determination of formaldehyde in aqueous solutions. The method measures the intensity of optical reflection.…”

Fiber optic sensors have been developed taking advantage on the synergy between the properties of nanostructured materials and the ones that characterize an optical fiber. The mechanical properties of optical fiber introduce some restrictions to the techniques used for the deposition of materials. As an alternative to the classical deposition procedures, wet coating techniques have been successfully applied in these cases. The current chapter put emphasis on materials that can be incorporated using wet coating techniques. The first one presented is the multilayer based nanostructures: among the different alternatives, we have focused on materials prepared with the Layer-by-Layer technique. Another type of products used for the fabrication of optical fiber sensors is sol-gel matrices, which are made of silica, so that its optical properties are similar to the ones of an optical fiber. The other two described type of products have focused the attention of many researchers in the recent years. Firstly, materials with an enhanced selectivity are presented: the molecularly imprinted polymers (MIPs). Finally, sensors based on metallic nanolayers and particles are presented. All these materials and techniques have acquired a great importance in the field of optical fiber sensors due to their versatility and the good features that offer.

“…Recently, molecularly imprinted polymers (MIPs) [1][2][3], as a recognition element for sensors, have increasingly attracted considerable attention. Molecular imprinting involves positioning functional monomers around the template molecules by non-covalent interaction or reversible covalent interaction, followed by polymerization and the template removal.…”

A sensitive molecularly imprinted electrochemical sensor was developed for selective detection of streptomycin by combination of mercaptoacetic acid-modified PbS nanoparticles with Au-coated Fe 3 O 4 magnetic nanoparticles dispersed multi-walled carbon nanotubes doped chitosan film. The imprinted sensor was fabricated onto the Au electrode via stepwise modification of nanocomposites and an electrodeposited thin film of molecularly imprinted polymers via sol-gel technology. The morphologies and electrochemical behaviors of the imprinted sensor were characterized by scanning electron microscope, cyclic voltammetry, and differential pulse voltammetry, respectively. The prepared sensor showed very high recognition ability and selectivity for streptomycin. Under optimal conditions, the imprinted sensor displayed good electrocatalytic activity to the redox of streptomycin. And the differential voltammetric anodic peak current was linear to the logarithm of streptomycin concentration in the range from 1.0×10 −6 to 1.0×10 −3 mol L −1 , and the detection limit obtained was 1.5×10 −9 mol L −1 . This proposed imprinted sensor was used successfully for streptomycin determination in different injection solution samples.
