“…Applying this tandem ''diazonium reduction/ATRP'' approach, we have studied the resistance of PS, PMMA, and polyglycidol to protein adsorption; 69 prepared chelatant adsorbents by grafting PGMA 26 or PMAA from PtBMA 68 in order to capture metal ions; and designed molecularly imprinted polymer grafts 25 as well as thermosensitive polymer brush-immobilized gold nanoparticles for optical sensor applications. 77 Taking advantage of the strong polymer-surface adhesion resulting from the ''diazonium reduction/ATRP'' process, Shaulov et al 24 have grafted PMMA to stainless steel (SS) stents which were further spray-coated with a drug-in-polymer matrix [poly(n-butyl methacrylate)/poly(ethylene-co-vinyl acetate) + paclitaxel (anti-tumor drug)].…”

“…Recently, we have combined electrografting of diazonium salts with ATRP to develop interesting carbon fibre microelectrode sensors. 26 A brominated diazonium salt was grafted to the carbon fibres (CF-Br) to use them as macroinitiators for the controlled growth of ultrathin films of poly(glycidyl methacrylate) (PGMA), via surface-initiated ATRP for 6 h resulting in CF-PGMA hybrids. PGMA is a very interesting functional polymer with an easily transferable epoxy group in each repeat unit.…”

“…Diazonium compounds were also employed to bind macromolecules to materials of diverse natures and shapes by grafting from [16][17][18][19][20] and grafting onto approaches. [21][22][23] Via either way, it is possible to design carbon fiber composites, 21 adherent coatings on drug eluting stents; 24 chemo- 25,26 and biosensors. 27 Hairyw carbon nanotubes designed by the grafting onto route were further used to design CNT/Pd heterostructures that are efficient catalysts for the Suzuki coupling reaction.…”

This critical review summarizes existing knowledge on the use of diazonium salts as a new generation of surface modifiers and coupling agents for binding synthetic polymers, biomacromolecules, and nanoparticles to surfaces. Polymer grafts can be directly grown at surfaces through the so-called grafting from approaches based on several polymerization methods but can also be pre-formed in solution and then grafted to surfaces through grafting onto strategies including "click" reactions. Several routes are also described for binding biomacromolecules through aryl layers in view of developing biosensors and protein arrays, while the use of aryl diazonium coupling agents is extended to the attachment of nanoparticles. Patents and industrial applications of the surface chemistry of diazonium compounds are covered. This review stresses the paramount role of aryl diazonium coupling agents in adhesion, surface and materials sciences (114 references).

Poly(glycidyl methacrylate), PGMA, was prepared via ATRP in bulk solution, and its epoxy groups were further acid-hydrolyzed in order to obtain a polymer with glycerol moieties (noted POH). The POH chain end C-Br bonds were subjected to a nucleophilic attack by NaN(3), resulting in azide-terminated POH (POH-N(3)). The CNTs were modified by in-situ-generated alkynylated diazonium cations from the para-alkynylated aniline of the formulas H(2)N-C(6)H(4)-C≡C-H, yielding CNT-C(6)H(4)-C≡C-H nanotubes. The azide-functionalized polymer POH-N(3) was clicked to the alkynyl-modified CNTs giving CNT@POH hybrids, which were further subjected to an oxidation resulting in carboxylated polymer-modified CNTs (noted CNT@PCOOH). The as-designed hairy CNTs served as efficient platforms for the in-situ synthesis and massive loading of 3 nm sized palladium nanoparticles (NPs). The CNT@PCOOH@Pd heterostructures prepared so far exhibited an efficient catalytic effect in the C-C Suzuki coupling reaction and were regenerated up to four times without any significant loss of catalytic activity.

“…The acid treated graphite powder was then dried in vacuum oven for 24 h at 80 • C. Dried graphite powder in a glass beaker was then placed in a conventional microwave oven and heated at 800 W for 10 s. Microwave irradiation resulted in the rapid expansion of graphite layers and resulted in the formation of graphene flakes. 28,29 Produced graphene flakes were tip sonicated and dispersed in dimethylformamide (DMF) and then brush-painted onto the paper substrates (10×10 cm). The sheet resistance of the graphene coated paper electrodes was controlled with the graphene loading and two different samples (10 and 60 ohm/sq) were prepared and utilized in this work.…”

In this work a novel approach was reported for glucose detection using disposable paper based electrodes consisting graphene modified with a conducting polymer, glucose oxidase (GOx) and gold nanoparticles. For the first time, a conducting polymer; poly(9,9-di-(2-ethylhexyl)-fluorenyl-2,7-diyl)-end capped with 2,5-diphenyl-1,2,4-oxadiazole (PFLO) was spread over graphene coated papers and used as a matrix for glucose detection. To finalize the desired biosensor, the enzyme GOx was immobilized with gold nanoparticles (AuNPs) via physical adsorption technique. Oxygen consumption was followed at −0.7 V vs Ag wire in a 50 mM, pH 6.0 phosphate buffer. The amperometric response of the GOx/graphene/PFLO/AuNPs-modified electrode was found to be linearly proportional to the glucose concentration. The fabricated biosensor revealed a high sensitivity for glucose in a linear range from 0.1 to 1.5 mM with a low detection limit of 0.081 mM at a signal-to-noise ratio of 3. K M App , I max , and sensitivity were calculated as 0.229 mM, 2.198 μA, and 7.357 μA/mM cm 2 , respectively. Finally, the constructed disposable biosensor was successfully utilized for the determination of glucose in commercial beverages.
