“…To crosslink the chitosan used in sensors based on MIPs, two methods are used; either the crosslinking agent is mixed with the template/polymer complex before deposition on the working electrode surface; in this case the crosslinking agent/functional monomer ratio is very important [86]. The second method is based on the deposition of the template/polymer complex on the electrode and then impregnating the modified electrode in the cross-linker solution.…”

Despite the enormous development of instruments for analyzing a wide variety of compounds, applied in different fields such as health, environment or quality control, the demand for increasingly sensitive and selective techniques continues to grow. In this regard, efforts have been made to highlight more appropriate techniques. Electrochemical sensors based on molecularly imprinted polymers (MIPs) offer an interesting alternative since they allow reaching high sensitivity and selectivity and they are inexpensive and easily adaptable to miniaturization. The choice of the functional monomer in the synthesis of MIPs is based on its capacity to provide complementary interactions with the target molecules. The various excellent properties of chitosan, as a biosourced polymer, make it a promising alternative to conventional functional monomers. This review reports on the principle of the MIPs technique describing the different possible approaches in their synthesis. It aims to provide an overview of the value of using chitosan as a functional monomer by highlighting its applications in electrochemical sensors.

“…As reported, Shen et al developed highly monodispersed Cu‐ and Ag‐based bimetallic nanocrystals for the efficient catalyst of CO oxidation [5]. Besides, AgNPs possess strong antimicrobial properties against various species of bacteria, low toxicity to human beings, and a long‐term antibacterial efficiency, now that they have been applied in many related fields, such as pharmaceutical, silver‐coated medical devices, textiles, food packaging, and so on [9–12].…”

Uniformly dispersed Ag nanoparticles (AgNPs) with diameter about 5 nm embedded in electrospun polyacrylonitrile (PAN) nanofibers were synthesized by using tea polyphenols (TP) as the reductant. The reducing ability of TP toward Ag ions was characterized by Fourier transform infrared spectroscopy and ultraviolet–visible spectra, and the results revealed that TP exhibit satisfied reducing ability in the synthesis process. Transmission electron microscopy observation showed that the synthesized spherical AgNPs with diameter about 5 nm were immobilized on the surface and in the interior of PAN nanofibers by electrospinning technology. The interactions of Ag with PAN and TP were investigated by X‐ray photoelectron spectroscopy (XPS), and the results suggested that PAN polymer and TP both served as stabilizer during the synthesis of AgNPs because of the chelating interactions of Ag with cyano groups and phenolic hydroxyls. The synthesized AgNPs in PAN nanofibers exhibit good antibacterial property and may be used for antibacterial and catalytic applications. POLYM. ENG. SCI., 2013. © 2012 Society of Plastics Engineers

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.
