“…Such thin films are common in thin-film devices because of the wide array of useful polymer types, including biopolymers, such as proteins [36,37], polysaccharides [38,39] and polypeptides [40]. LbL film-modified devices are used in biosensors [41], ion-selective membranes [42], stimuli-sensitive systems [43] and drug delivery [44].…”

This article reviews recent progress in the development of ferrocene (Fc)-modified thin films and nanoparticles in relation to their biosensor applications. Redox-active materials in enzyme biosensors commonly use Fc derivatives, which mediate electron transfer between the electrode and enzyme active site. Either voltammetric or amperometric signals originating from redox reactions of Fc are detected or modulated by the binding of analytes on the electrode. Fc-modified thin films have been prepared by a variety of protocols, including in situ polymerization, layer-by-layer (LbL) deposition, host-guest complexation and molecular recognitions. In situ polymerization provides a facile way to form Fc thin films, because the Fc polymers are directly deposited onto the electrode surface. LbL deposition, which can modulate the film thickness and Fc content, is suitable for preparing well-organized thin films. Other techniques, such as host-guest complexation and protein-based molecular recognition, are useful for preparing Fc thin films. Fc-modified Au nanoparticles have been widely used as redox-active materials to fabricate electrochemical biosensors. Fc derivatives are often attached to Au nanoparticles through a thiol-Au linkage. Nanoparticles consisting of inorganic porous materials, such as zeolites and iron oxide, and nanoparticle-based composite materials have also been used to prepare Fc-modified nanoparticles. To construct biosensors, Fc-modified nanoparticles are immobilized on the electrode surface together with enzymes.

“…(i) The origin of the internal charge compensation, which can be either of intrinsic [40,41] or of extrinsic nature [5,42,43], meaning that electroneutrality in the bulk of the film is due to the quantitative ion pairing between the polycation and the polyanion or to the incorporation of an excess of small electrolytes, respectively. (ii) The understanding of the film growth regime.…”

“…Free electro-active molecules can be incorporated into exponentially grown films leading to electroresponsive properties in those films [104][105][106]110,111]. Under an applied potential, oxidation of ferrocyanide ions confined in a polyglutamic acid (PGA)/PAH LbL film, leads to a loss of one charge per molecule.…”

No. of Pages 30 2 G. Rydzek et al. SummaryDuring the last few decades, electrochemistry and electrode modification have seen a tremendous fall off in creativity with the emergence of the nanoarchitectonic-based layerby-layer (LbL) film deposition technique. An unprecedented variety of building blocks can be immobilized on surfaces, leading to progress in several fields including sensing, electrochromic, electro-responsive and energy devices. This review describes the state of the art of electrochemical devices based on LbL assemblies, with a focus on supercapacitors, biosensors, and electroresponsive LbL such as electrodissolution/electroswelling of coatings. Recently, electrochemistry has also been used as an ''active trigger'' to induce the formation of films by covalent coupling, leading to new nanoarchitectonic approaches beyond the LbL strategy. These emerging electro-coupling reactions, including electroclick and carbazole chemistry, open new perspectives toward architecture and patterning of functional films and are extensively reviewed.
