“…The high-resolution O 1s peaks of the TNT group were resolved into two peaks at 529.9 and 531.1 eV ( Figure 1 D), which are attributed to Ti-O and Ti-OH species, respectively [ 33 ]. The high-resolution O 1s peaks of the TNT-GO group were resolved into four peaks at approximately 529.9, 531.1, 532.1, and 533 eV, which are attributed to Ti-O, Ti-OH/C=O, C-O, and C-OH, respectively [ 32 , 34 ], further proving the loading of GO. The surface roughness (Ra) of each group of specimens was detected using atomic force microscopy (AFM).…”

Surface topography, protein adsorption, and the loading of coating materials can affect soft tissue sealing. Graphene oxide (GO) is a promising candidate for improving material surface functionalization to facilitate soft tissue integration between cells and biomaterials. In this study, TiO2 nanotubes (TNTs) were prepared by the anodization of Ti, and TNT-graphene oxide composites (TNT-GO) were prepared by subsequent electroplating. The aim of this study was to investigate the effect of TNTs and TNT-GO surface modifications on the behavior of human gingival fibroblasts (HGFs). Commercially pure Ti and TNTs were used as the control group, and the TNT-GO surface was used as the experimental group. Scanning electron microscopy, X-ray photoelectron spectroscopy, and X-ray diffraction were used to perform sample characterization. Cell adhesion, cell proliferation, cell immunofluorescence staining, a wound-healing assay, real-time reverse-transcriptase polymerase chain reaction (RT-PCR), and Western blotting showed that the proliferation, adhesion, migration, and adhesion-related relative gene expression of HGFs on TNT-GO were significantly enhanced compared to the control groups, which may be mediated by the activation of integrin β1 and the MAPK-Erk1/2 pathway. Our findings suggest that the biological reactivity of HGFs can be enhanced by the TNT-GO surface, thereby improving the soft tissue sealing ability.

“…Our sensor integrates three electrodes out of the same material and in the form of screen‐printed electrodes widely used in flexible architectures for electrochemical sensing. [ 47 ] The CV curve obtained during the sensing measurements demonstrates a typical behavior for potassium ferricyanide detection, indicating two clear redox peaks. [ 48 ] The high sensitivity is justified by the current value exceeding 1 mA.…”

Polyethylene terephthalate (PET) is the most widely used polymer in the world. For the first time, the laser‐driven integration of aluminum nanoparticles (Al NPs) into PET to realize a laser‐induced graphene/Al NPs/polymer composite, which demonstrates excellent toughness and high electrical conductivity with the formation of aluminum carbide into the polymer is shown. The conductive structures show an impressive mechanical resistance against >10000 bending cycles, projectile impact, hammering, abrasion, and structural and chemical stability when in contact with different solvents (ethanol, water, and aqueous electrolytes). Devices including thermal heaters, carbon electrodes for energy storage, electrochemical and bending sensors show this technology's practical application for ultra‐robust polymer electronics. This laser‐based technology can be extended to integrating other nanomaterials and create hybrid graphene‐based structures with excellent properties in a wide range of flexible electronics’ applications.

“…In both cases, the broadened 2D peak was suggestive of multi-layer graphene, with a shi and an additional peak at about 653 cm À1 which was because of the incorporation of AgNPs on the EG surface. 29 The FESEM images (Fig. 4) show exfoliated sheets for EG which were morphologically different from that of pristine graphite akes (Fig.…”
