“…The heat treatment protocol was adapted from the traditional heat treatment protocol in C-MEMS. [22,[57][58][59][60][61] Briefly, the heating protocol consisted of five stages: i) heating from room temperature to 350 °C with a heating ramp of 3 °C min −1 ; ii) isothermal heating at 350 °C for 3 h; iii) ramping from 350 °C to the final temperature with the ramp rate of 3 °C min −1 ; iv) isothermal heating at the final temperature for 2 h; and v) cooling down from the final temperature to room temperature using natural cooling. The final temperature was varied from 500 to 900 °C.…”

The integration of additive manufacturing technologies with the pyrolysis of polymeric precursors enables the design‐controlled fabrication of architected 3D pyrolytic carbon (PyC) structures with complex architectural details. Despite great promise, their use in cellular interaction remains unexplored. This study pioneers the utilization of microarchitected 3D PyC structures as biocompatible scaffolds for the colonization of muscle cells in a 3D environment. PyC scaffolds are fabricated using micro‐stereolithography, followed by pyrolysis. Furthermore, an innovative design strategy using revolute joints is employed to obtain novel, compliant structures of architected PyC. The pyrolysis process results in a pyrolysis temperature‐ and design‐geometry‐dependent shrinkage of up to 73%, enabling the geometrical features of microarchitected compatible with skeletal muscle cells. The stiffness of architected PyC varies with the pyrolysis temperature, with the highest value of 29.57 ± 0.78 GPa for 900 °C. The PyC scaffolds exhibit excellent biocompatibility and yield 3D cell colonization while culturing skeletal muscle C2C12 cells. They further induce good actin fiber alignment along the compliant PyC construction. However, no conclusive myogenic differentiation is observed here. Nevertheless, these results are highly promising for architected PyC scaffolds as multifunctional tissue implants and encourage more investigations in employing compliant architected PyC structures for high‐performance tissue engineering applications.

“…However, the selection of compatible precursor materials for carbon and metal becomes a crucial factor, which often makes the precursor preparation more complex. As a potential solution to this, we recently introduced an anodically electrodeposited metal/chitosan hydrogel as a novel precursor for metal/carbon composite material [13]. Electrodeposition is a well-established electrochemical method employed for creating a coating on the conductive surface of an electrode [14][15][16].…”

“…However, contrasting to cathodic gels, the anodic gel appeared blue due to the incorporation of Cu 2+ ions from the copper anode, making it a facile method for precursor preparation. Carbonization of the anodically electrodeposited copper/chitosan composite further resulted in a copper/carbon composite [13]. However, typical carbonization processes possess several disadvantages.…”

This work presents anodically electrodeposited copper (Cu)/chitosan gel as a novel precursor for synthesizing a Cu/carbon nanocomposite through laser-induced carbonization. Metal/carbon nanocomposites offering advantageous properties compared to their individual counterparts stand out in various applications, particularly in those involving electrochemical phenomena. However, their synthesis often suffers from complicated and time-consuming synthesis procedures. Here, we integrate anodic electrodeposition and laser-induced carbonization to yield a rapid, simple, and inexpensive procedure for synthesizing metal/carbon nanocomposite. A precursor composite involving Cu-coordinated chitosan film is achieved through anodic electrodeposition on a copper anode. Irradiation by an infrared laser with optimized parameters results in the thermochemical decomposition of the Cu/chitosan composite, rapidly forming a nanocomposite material featuring highly graphitized and porous carbon materials. Elemental mapping confirms the formation of the nanocomposite, although no crystalline phases of copper are observed during X-ray diffraction. This can be attributed to the rapid nature of the laser-carbonization process. The nanocomposite material is further demonstrated for electrochemical sensing of hydrogen peroxide (H2O2), exhibiting a sensitivity of 2.65 mM−1 for concentrations ranging from 0.01 mM to 0.1 mM H2O2, and 0.01 ± 0.01 mM−1 for concentrations from 0.1 to 10 mM H2O2. These sensitivities are comparable to other non-enzymatic H2O2 biosensors. The finding of this work signifies a rapid and facile method for synthesizing metal/carbon nanocomposites with strong implications for the field of biosensors.

“…In the literature, efforts have been made to theoretically understand the mechanisms of copper electrodeposition 31 – 33 . In turn, in the latest research, articles focusing on potential applications of composite materials containing copper and its oxides obtained electrochemically lead the way 34 – 37 . Therefore, in this work we would like to place special emphasis on the characterization of ECD on the carbon nanotubes coated stainless steel using copper(II) sulphate solutions.…”

The nanocomposite coatings composed of carbon nanotubes and various forms of copper were prepared in the two-step process. Firstly, carbon nanotubes were coated on stainless steel substrate using electrophoretic deposition at constant current. Then, the process of electrochemical deposition using copper(II) sulphate solutions was performed under high overpotential conditions. The modification of the copper(II) cations concentration in the solution and the deposition time provided the formation of various forms of crystals. The samples and their cross-sections were observed and examined using scanning electron microscope equipped with electron dispersive spectroscopy system. The analysis of chemical composition revealed that in addition to the pure copper crystals, the crystals characterized by the presence of copper and oxygen were formed. Therefore, Raman spectroscopy was applied to determine the unknown stoichiometry of this copper oxide. The point and in-depth analysis identified copper(I) oxide in the form of different size crystals depending on the concentration of the copper(II) sulphate solution. To confirm these findings, grazing incidence X-ray diffraction measurements were also performed. the combination of the applied methods has provided the detailed description of the preparation of the nanocomposite coatings with the proposed mechanism of copper(I) oxide formation.
