Reduction–oxidation (redox) reactions provide a distinct modality for biological communication that is fundamentally different from the more‐familiar ion‐based electrical modality. Biology uses these two modalities for communication through different systems (immune versus nervous), and uses different mechanisms to control the flow of the charge carriers: the flow of soluble ions is controlled using structural barriers (i.e., membranes) and gates (e.g., membrane‐spanning protein channels), while the flow of insoluble electrons is controlled using redox‐reaction networks. Here, a simple electrochemical approach to pattern catechols onto a flexible polysaccharide hydrogel is reported and it is demonstrated that the patterned catechol regions serve as nodes for the mediated flow of electrons through redox reactions. Electron flow through this node involves the switching of binary redox states (oxidized and reduced) and this node's redox state can be detected (i.e., “read”) by passively observing its optical absorbance, or actively switching its redox‐state electrochemically. Further, this catechol node can be switched through biological mechanisms, and this enables the fabricated catechol node to be embedded within biochemical redox reaction networks to facilitate the spanning of bio‐electronic communication. Thus, it is envisioned that catechols can emerge as a molecular equivalent to a transistor for miniaturize‐able, deployable and sustainable redox‐linked bioelectronics.

“…The experimental evidence indicates that coating SyP-electospun scaffolds with pDA is an effective strategy for promoting cell remodeling, although the underlying mechanism is not fully understood. The ability of pDA to confer hydrophilicity to surfaces, 66,71,72 to bind bioactive molecules, [73][74][75] and to (presumably) trigger cell-signaling pathways [76][77][78] may provide elements that can explain the observed outcomes.…”

“…Until recently, specific interactions between the cell surface and the materials had to be considered for cell nanoencapsulation, which was solved in part when polyphenolic compounds were found to coat virtually all the substances. [ 37,104 ] Polyphenolics include the chemicals that contain catechol (1,2‐dihydroxybenzene) and/or pyrogallol (1,2,3‐trihydroxybenzene) groups in their structure, and dopamine and tannic acid (TA) are the representatives of the coating materials used. [ 35,36 ] For example, polydopamine (PD) films are formed on any substrates via oxidative self‐polymerization in the tris(hydroxymethyl)aminomethane buffer (Tris, pH 8.5) ( Figure a).…”

“…The LbL method has been a primary choice for cell‐surface modifications, because it has some other advantages than cytocompatibility, such as materials availability, and composition and structure tunability. [ 31–34 ] Polyphenolics‐based coating is another cytocompatible method, developed in the last decade, [ 35–37 ] for nanocoating of mammalian cells. [ 38 ] Other coating techniques also have been suggested in this direction, such as surface‐initiated polymerization (SIP), in situ hydrogelation, and bioinspired mineralization.…”

Strategic advances in the single‐cell nanocoating of mammalian cells have noticeably been made during the last decade, and many potential applications have been demonstrated. Various cell‐coating strategies have been proposed via adaptation of reported methods in the surface sciences and/or materials identification that ensure the sustainability of labile mammalian cells during chemical manipulation. Here an overview of the methodological development and potential applications to the healthcare sector in the nanocoating of mammalian cells made during the last decade is provided. The materials used for the nanocoating are categorized into polymers, hydrogels, polyphenolic compounds, nanoparticles, and minerals, and the corresponding strategies are described under the given set of materials. It also suggests, as a future direction, the creation of the cytospace system that is hierarchically composed of the physically separated but mutually interacting cellular hybrids.
