Abstract
This review is focused on current state-of-the-art research on electroactive-based materials and their synthesis, as well as their physicochemical and biological properties. Special attention is paid to pristine intrinsically conducting polymers (ICPs) and their composites with other organic and inorganic components, well-defined micro- and nanostructures, and enhanced surface areas compared with those of conventionally prepared ICPs. Hydrogels, due to their defined porous structures and being filled with aqueous solution, offer the ability to increase the amount of immobilized chemical, biological or biochemical molecules. When other components are incorporated into ICPs, the materials form composites; in this particular case, they form conductive composites. The design and synthesis of conductive composites result in the inheritance of the advantages of each component and offer new features because of the synergistic effects between the components. The resulting structures of ICPs, conducting polymer hydrogels and their composites, as well as the unusual physicochemical properties, biocompatibility and multi-functionality of these materials, facilitate their bioapplications. The synergistic effects between constituents have made these materials particularly attractive as sensing elements for biological agents, and they also enable the immobilization of bioreceptors such as enzymes, antigen-antibodies, and nucleic acids onto their surfaces for the detection of an array of biological agents. Currently, these materials have unlimited applicability in biomedicine. In this review, we have limited discussion to three areas in which it seems that the use of ICPs and materials, including their different forms, are particularly interesting, namely, biosensors, delivery of drugs and tissue engineering.

Degradable conductive self-healing hydrogels based on dextran-graft-tetraaniline and N-carboxyethyl chitosan as injectable carriers for myoblast cell therapy and muscle regeneration. Acta Biomater 2019; 84:180-193. [PMID: 30528606 DOI: 10.1016/j.actbio.2018.12.008] [Citation(s) in RCA: 194] [Impact Index Per Article: 38.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2018] [Revised: 11/05/2018] [Accepted: 12/04/2018] [Indexed: 12/25/2022]
Abstract
Injectable conductive hydrogels have great potential as tissue engineering scaffolds and delivery vehicles for electrical signal sensitive cell therapy. In this work, we present the synthesis of a series of injectable electroactive degradable hydrogels with rapid self-healing ability and their potential application as cell delivery vehicles for skeletal muscle regeneration. Self-healable conductive injectable hydrogels based on dextran-graft-aniline tetramer-graft-4-formylbenzoic acid and N-carboxyethyl chitosan were synthesized at physiological conditions. The dynamic Schiff base bonds between the formylbenzoic acid and amine group from N-carboxyethyl chitosan endowed the hydrogels with rapid self-healing ability, which was verified by rheological test. Equilibrated swelling ratio, morphology, mechanical strength, electrochemistry and conductivity of the injectable hydrogels were fully investigated. The self-healable conductive hydrogels showed an in vivo injectability and a linear-like degradation behavior. Two different kinds of cells (C2C12 myoblasts and human umbilical vein endothelial cells (HUVEC)) were encapsulated in the hydrogels by self-healing effect. The L929 fibroblast cell culture results indicated the biocompatibility of the hydrogels. Moreover, the C2C12 myoblast cells were released from the conductive hydrogels with a linear-like profile. The in vivo skeletal muscle regeneration was also studied in a volumetric muscle loss injury model. All these data indicated that these biodegradable self-healing conductive hydrogels are potential candidates as cell delivery vehicles and scaffolds for skeletal muscle repair. STATEMENT OF SIGNIFICANCE: Injectable hydrogels with self-healing and electrical conductivity properties are excellent candidates as tissue-engineered scaffolds for myoblast cell therapy and skeletal muscle regeneration. The self-healing property of these hydrogels can prolong their lifespan. However, most of the reported conductive hydrogels are not degradable or do not have the self-healing ability. Herein, we synthesized antibacterial conductive self-healing hydrogels as a cell delivery carrier for cardiac cell therapy based on chitosan-grafted-tetraaniline hydrogels synthesized in our previous work. However, an acid solution was used to dissolve the polymers in that study, which may induce toxicity to cells. In this work, we synthesized a series of injectable electroactive biodegradable hydrogels with rapid self-healing ability composed of N-carboxyethyl chitosan (CECS) and dextran-graft-aniline oligomers, and these hydrogel precusor can dissolve in PBS solution of pH 7.4; we further demonstrated their potential application as cell delivery vehicles for skeletal muscle regeneration.

A simple strategy to enhance the in vivo wound-healing activity of curcumin in the form of self-assembled nanoparticle complex of curcumin and oligochitosan. MATERIALS SCIENCE & ENGINEERING. C, MATERIALS FOR BIOLOGICAL APPLICATIONS 2018; 98:54-64. [PMID: 30813056 DOI: 10.1016/j.msec.2018.12.091] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/13/2018] [Revised: 12/11/2018] [Accepted: 12/25/2018] [Indexed: 10/27/2022]
Abstract
While the wound healing activity of curcumin (CUR) has been well-established, its clinical effectiveness remains limited due to the inherently low aqueous CUR solubility, resulting in suboptimal CUR exposure in the wound sites. Previously, we developed high-payload amorphous nanoparticle complex (or nanoplex) of CUR and chitosan (CHI) capable of CUR solubility enhancement by drug-polyelectrolyte complexation. The CUR-CHI nanoplex, however, exhibited poor colloidal stability due to its strong agglomeration tendency. Herein we hypothesized that the colloidal stability could be improved by replacing CHI with its oligomers (OCHI) owed to the better charge distribution in OCHI. The effects of key parameters in drug-polyelectrolyte complexation (i.e. pH, salt inclusion, CUR concentration, and OCHI/CUR charge ratio) on the physical characteristics and preparation efficiency of the CUR-OCHI nanoplex produced were investigated. The in vivo wound healing efficacy of the CUR-OCHI nanoplex and its cytotoxicity towards human keratinocytes cells were examined. The results showed that CUR-OCHI nanoplex exhibited prolonged colloidal stability (72 h versus <24 h for the CUR-CHI nanoplex). At the optimal condition, the CUR-OCHI nanoplex (without ultrasonication) exhibited size, zeta potential, and CUR payload of ≈140 nm, 20 mV, and 78% (w/w), respectively. The nanoplex preparation was simple yet robust at nearly 100% CUR utilization rate. The CUR-OCHI nanoplex exhibited superior wound healing efficacy to the native CUR with wound closure of >90% after 7 days versus 9 days for the native CUR resulting in smaller scars, attributed to its generation of high CUR concentration in the wound sites.

Abstract
Three-dimensional scaffolds for cellular organization need to enjoy a series of specific properties. On the one hand, the morphology, shape and porosity are critical parameters and eventually related with the mechanical properties. On the other hand, electrical conductivity is an important asset when dealing with electroactive cells, so it is a desirable property even if the conductivity values are not particularly high. Here, we construct three-dimensional (3D) porous and conductive composites, where C8-D1A astrocytic cells were incubated to study their biocompatibility. The manufactured scaffolds are composed exclusively of carbon nanotubes (CNTs), a most promising material to interface with neuronal tissue, and polypyrrole (PPy), a conjugated polymer demonstrated to reduce gliosis, improve adaptability, and increase charge-transfer efficiency in brain-machine interfaces. We developed a new and easy strategy, based on the vapor phase polymerization (VPP) technique, where the monomer vapor is polymerized inside a sucrose sacrificial template containing CNT and an oxidizing agent. After removing the sucrose template, a 3D porous scaffold was obtained and its physical, chemical, and electrical properties were evaluated. The obtained scaffold showed very low density, high and homogeneous porosity, electrical conductivity, and Young's Modulus similar to the in vivo tissue. Its high biocompatibility was demonstrated even after 6 days of incubation, thus paving the way for the development of new conductive 3D scaffolds potentially useful in the field of electroactive tissues.

Abstract
Conducting polymers are routinely used in optoelectronic biomaterials, but large polymer polydispersity and poor aqueous compatibility complicate integration with biomolecular templates and development of discrete and defined supramolecular complexes. Herein, we report on a chiro-optical hybrid material generated by the self-assembly of an anionic peptide and a chemically defined cationic pentameric thiophene in aqueous environment. The peptide acts as a stereochemical template for the thiophene and adopts an α-helical conformation upon association, inducing optical activity in the thiophene π-π* transition region. Theoretical calculations confirm the experimentally observed induced structural changes and indicate the importance of electrostatic interactions in the complex. The association process is also probed at the substrate-solvent interface using peptide-functionalized gold nanoparticles, indicating that the peptide can also act as a scaffold when immobilized, resulting in structurally well-defined supramolecular complexes. The hybrid complex could rapidly be assembled, and the kinetics of the formation could be monitored by utilizing the local surface plasmon resonance originating from the gold nanoparticles. We foresee that these findings will aid in designing novel hybrid materials and provide a possible route for the development of functional optoelectronic interfaces for both biomaterials and energy harvesting applications.

Abstract
Injectable hydrogels with multifunctional properties, including tissue adhesiveness and pH-sensitivity are highly desired for localized drug delivery in disease treatment, and their design is still challenging. We developed a series of multifunctional injectable mucoadhesive and pH-responsive hydrogels based on chitosan-grafted-dihydrocaffeic acid (CS-DA) and oxidized pullulan (OP) via a Schiff base reaction. These hydrogels exhibited good injectability, suitable gelation time, in vitro pH-dependent equilibrated swelling ratios, morphologies, and rheological characteristics. The desirable in vitro pH-sensitive drug release behavior of these hydrogels was demonstrated by a drug release test with anti-cancer drug doxorubicin (DOX) loaded hydrogels at different pH values. The hydrogels showed good DOX release, effectively killing colon tumor cells (HCT116 cells) and good antibacterial properties against E. coli and S. aureus in vitro when the antibacterial model drug amoxicillin was encapsulated in the hydrogels. A lap-shear test was also carried out with these hydrogels. The hydrogels exhibited good mucosal adhesion, indicating their potential use in mucosa-localized drug delivery systems. All these results suggest that these injectable pH-responsive adhesive hydrogels are ideal candidates for development of colon cancer drug delivery carriers or mucoadhesive drug delivery systems.

Abstract
The controversy between polypyrrole's (Ppy) biocompatibility and its aggregation on nanofibers impedes application of conductive Ppy-incorporated nanofibers to create engineered cardiac microenvironments. The purpose of this study was to fabricate a functional scaffold for engineering cardiac patches (ECP) using a high concentration of methyl acrylic anhydride-gelatin (GelMA)-Ppy nanoparticles, mussel-inspired crosslinker, and electrospun (ES)-GelMA/polycaprolactone (PCL) nanofibrous membrane. Methods: First, spherical GelMA-Ppy nanoparticles were obtained when the methacrylate groups of GelMA formed a self-crosslinked network through oxidative polymerization of Ppy. Second, GelMA-Ppy nanoparticles were uniformly crosslinked on the ES-GelMA/PCL membrane through mussel-inspired dopamine-N'N'-methylene-bis-acrylamide (dopamine-MBA) crosslinker. Finally, the feasibility of the dopa-based conductive functional ECP scaffold was investigated in vitro and in vivo. Results: The GelMA-Ppy nanoparticles displayed excellent biocompatibility at a high concentration of 50 mg/mL. The massive GelMA-Ppy nanoparticles could be uniformly distributed on the ES nanofibers through dopamine-MBA crosslinker without obvious aggregation. The high concentration of GelMA-Ppy nanoparticles produced high conductivity of the dopamine-based (dopa-based) conductive membrane, which enhanced the function of cardiomyocytes (CMs) and yielded their synchronous contraction. GelMA-Ppy nanoparticles could also modify the topography of the pristine ES-GelMA/PCL membrane to promote vascularization in vitro. Following transplantation of the conductive membrane-derived ECP on the infarcted heart for 4 weeks, the infarct area was decreased by about 50%, the left ventricular shortening fraction percent (LVFS%) was increased by about 20%, and the neovascular density in the infarct area was significantly increased by about 9 times compared with that in the MI group. Conclusion: Our study reported a facile and effective approach to developing a functional ECP that was based on a mussel-inspired conductive nanofibrous membrane. This functional ECP could repair infarct myocardium through enhancing cardiac function and revascularization.

Abstract
Nanocomposite hydrogels based on carbon nanotubes (CNTs) are known to possess remarkable stiffness, electrical, and thermal conductivity. However, they often make use of CNTs as fillers in covalently cross-linked hydrogel networks or involve direct cross-linking between CNTs and polymer chains, limiting processability properties. Herein, nanocomposite hydrogels are developed, in which CNTs are fillers in a physically cross-linked hydrogel. Supramolecular nanocomposites are prepared at various CNT concentrations, ranging from 0.5 to 6 wt%. Incorporation of 3 wt% of CNTs leads to an increase of the material's toughness by over 80%, and it enhances electrical conductivity by 358%, compared to CNT-free hydrogel. Meanwhile, the nanocomposite hydrogels maintain thixotropy and processability, typical of the parent hydrogel. The study also demonstrates that these materials display remarkable cytocompatibility and support cell growth and proliferation, while preserving their functional activities. These supramolecular nanocomposite hydrogels are therefore promising candidates for biomedical applications, in which both toughness and electrical conductivity are important parameters.
