“…By regulating nanotube concentration in the solution one can regulate the thickness of the film to be formed on the surface. As we have shown previously [13], the nanotube orientation and density on the surface can be controlled while using different deposition techniques: dipping, pulling, centrifugation, sputtering.…”

In this study we have developed a biocompatible current-conductive coating based on carbon nanotubes and bovine serum albumin and have shown its efficiency in culturing cells in vitro. We investigate the proliferation of human embryonic fibroblast (HEF) cells, which were subjected to electrical stimulation when cultured on carbon nanotube surface. A weak increase in proliferation is demonstrated at stimulating field pulses up to 100 mV. It is assumed that the transport mechanism accompanied by higher synthesis of proteins and their polymerization may increase proliferative activity at low voltages. At higher voltages the motility and spatial organization of HEF cell is observed. As a result, a novel technique of supplying the cells with electric field through a system of micro- and nanosized electrodes and a biocompatible composite have been developed

“…In a similar way, CNT thin films with complex structures can be fabricated using wafers containing interdigitated electrode elements [ 94 ]. Each of these electrode pairs directs part of the suspended nanotube solution into a geometric shape, which becomes part of the pattern of the thin film [ 94 ]. This method has been used to create electrically conductive channels that could be used for nanosensors [ 94 ].…”

“…Although this fabrication method can create larger films than the previous method, the maximum film area is still restricted by the size of the wafer. In addition, the capillary induced forces may cause misalignment of nanowires [ 94 ]. CNT thin films can also be applied as coatings to electrodes by AC electrophoresis.…”

Various nanowire or nanotube-based devices have been demonstrated to fulfill the anticipated future demands on sensors. To fabricate such devices, electric field-based methods have demonstrated a great potential to integrate one-dimensional nanostructures into various forms. This review paper discusses theoretical and experimental aspects of the working principles, the assembled structures, and the unique functions associated with electric field-based assembly. The challenges and opportunities of the assembly methods are addressed in conjunction with future directions toward high performance sensors.

“…Ideally, it is desired that CNTs of determined electrical types were precisely wired between the electrodes with stable contacts for device fabrication. [70][71][72][73][74] However, such precise control is extremely challenging due to the ultratiny size of the CNTs, high-resolution nanoscale positioning, and subtle structure diversity. Tremendous efforts have been made to solve the challenges.…”

An overview of laser-assisted techniques developed in our group for fabricating carbon nanostructures, including two-dimensional graphene, one-dimensional carbon nanotubes, and zero-dimensional carbon nanoonions, is presented. Unique laser-material interactions provide versatile possibilities in fabricating carbon nanostructures, including localized heating, direct laser writing, tip-enhanced optical near-field effect, polarization, ablation, resonant excitation, precise energy delivery, and mask-free direct patterning. Rapid single-step fabrication of graphene patterns was achieved using laser directing writing. Parallel integration of single-walled carbon nanotubes was realized by making use of tip-enhanced optical near-field effect. High-quality carbon nanoonions were obtained through laser resonant excitation of precursor molecules.
