“…in working with a variety of photoinitiators and most of the commonly applied functional monomers. [22] According to Scheme 1(a), [23] NMP includes a mediator with C-ON bond, which breaks into a stable aminoxyl or nitroxyl radical and a reactive carbon radical by heat. The carbon radical produced is able to initiate polymerization to form monodisperse polymer chains.…”

Molecular imprinting is an efficient tool for generating synthetic acceptors with specific recognition sites, which are mimed from template structures via polymerization. The final products of this strategy lead to high‐performance polymers with active recognition sites for a range of various applications in terms of extraction and separation, characterization and recognition, biomedicine, biosensors, and drug delivery. Molecular imprinting of biomacromolecules synthesizes a series of matrices that may be referred to as biomolecularly imprinted polymers (BMIPs). In this review article, an overview of different methods for fabricating BMIPs with an emphasis on novel polymerization schemes along with potential challenges is discussed. Additionally, selected applications of BMIPs will be briefly highlighted derived from the latest research papers. Copyright © 2016 John Wiley & Sons, Ltd.

“…Unlike traditional MIP synthesis, the elongation of the growing polymer proceeds in a controlled and ordered manner. Upon completion of the polymerization process the template is removed leaving voids with the affinity for the target (Salian & Byrne, 2013). To date model proteins such as lysozyme, BSA and myoglobin have been imprinted but this has now been extended to other biological targets such as Tobacco Mosaic Virus (Sun, 2013;Fig.…”

Highlights•Background to the evolution of biosensor based on nanoparticles.•Application of nanoparticles in biosensor devices.•Overview of biosensor formats applied in food testing.•Examples of integrated biosensor systems for food sampling.•Prospects and challenges in nanosensors in pathogen testing.The following will provide an overview on how advances in nanoparticle technology have contributed towards developing biosensors to screen for safety and quality markers associated with foods. The novel properties of nanoparticles will be described and how such characteristics have been exploited in sensor design will be provided. All the biosensor formats were initially developed for the health care sector to meet the demand for point-of-care diagnostics. As a consequence, research has been directed towards miniaturization thereby reducing the sample volume to nanolitres. However, the needs of the food sector are very different which may ultimately limit commercial application of nanoparticle based nanosensors. IntroductionThrough evolution we have developed senses to enable us to differentiate good foods from bad. The art of cheese making, brewing and viticulture has relied on the producer using their senses to assess quality. Establishing if a food was safe was more problematic and typically relied on tasters to ensure dishes provided to their masters were sound. Clearly, analytical testing is a more reliable and objective means of assessing the quality and safety of foods. Laboratory testing provided a basis for developing protocols and limits that could be applied to foods to define quality or safety. Yet, the expense and delay in acquiring results remain critical limitations. Consequently, there is an on-going demand for biosensors that can be used outside the laboratory environment to assess the safety and quality of foods on-site.In many instances the needs of the food industry mirrored that of the health sector where rapid diagnostics would enhance treatments and prognosis. The health sector provides a more lucrative market for diagnostic companies so it is not unexpected to find that the majority of research to date has been towards developing biosensors to meet the market demands. Consequently, those biosensors encountered in the food sector are derived from those devices initially fabricated to meet the needs of the health care sector. Within this context, the following review provides a brief history on how the field of biosensors developed and the contribution made by advances in nanoparticle technology. The efforts in transferring biosensor technologies to the food sector will be provided with a focus on safety, and to a degree, quality assessment. The review does not attempt to provide an exhaustive list of advances given the numerous quality reviews are already published in this area (Arugula and Simonian,

“…Atom-transfer radical polymerization (ATRP) is a powerful technique for controlled synthesis of polymers that provides several macromolecular architectures: polymers with narrow molecular weight distribution [1] , block copolymers [2,3] , random or gradient [4] and functionalized polymers [5][6][7][8][9] . ATRP has a great interest in the academic and industrial field because it can be used for various monomers, can be conducted in mild temperatures, and it is very resistant to impurities [10] .…”

SbstractThis paper uses a new kinetic modeling and simulations to analyse the effect of temperature on the polystyrene properties obtained by atom-transfer radical polymerization (ATRP). Differently from what has been traditionaly published in ATRP modeling works, it was considered "break" reactions in the mechanism aiming to reproduce the process at high temperatures. Results suggest that there is an upper limit temperature (130 °C), above which the polymer architecture loses the control. In addition, for the system considered in this work, the optimum operating temperature was 100 °C, because at this temperature polymer with very low polydispersity index is obtained, at considerable fast polymerization rate. Therefore, this present paper provides not only a tool to study ATRP processes by simulations, but also a tool for analysis and optimization, being a basis for future works dealing with this monomer and process.
