Visible-light-responsive reduced graphene oxide/g-C₃N₄/TiO₂ composite nanocoating for photoelectric stimulation of neuronal and osteoblastic differentiation

Abstract

rGO/g-C3N4/TiO2 nanocoating was fabricated on Ti-based implant for photoelectric stimulation of bone and nerve repair. The ternary nanocoating exerted greater photoelectric effects on enhancing osteoblastic differentiation and neurite outgrowth.

Control of Neuronal Survival and Development Using Conductive Diamond

“…The effects of light stimulation have been published on cells adhered to various photoelectric materials. − ,− Most previous studies used a single material, only examined cellular responses to one level of stimulation, and only reported the favorable effects of light exposure on cells. ,,,− By applying different surface treatments to N-UNCD, we were able to examine the cellular response to varying magnitudes of the photocurrent and their mechanisms. We generally observed that the 15-h OA N-UNCD sample produced the most beneficial effect on cells.…”

“…Some of the photoelectric materials that have been proposed and employed for controlling neuronal development and neurite outgrowth include silicon, conductive polymers such as poly­(3-hexylthiophene-2,5-diyl) (P3HT), − and carbon-based materials such as graphene oxide − and graphitic carbon nitride. − The favorable neural stimulation effects of these materials under illumination have been demonstrated using various cultured cell models, including pheochromocytoma (PC12) cells, ,,, primary cortical neurons, , and neural stem cells. ,− Most of these photosensitive materials generate Faradaic currents upon illumination via photoinduced electrons and holes. , Previous research indicates that the direct transfer of electrons (Faradaic charge injection) may have a negative impact on the survival of neurons due to the production of a high level of reactive oxygen species (ROS) . Therefore, additional chemicals, such as ascorbic acid, are required to scavenge the photoexcited holes in the cultures, , which limits their in vivo and clinical applications.…”

Real-time Monitoring Method of Insulation Status of Photoelectric Composite Submarine Cable based on Thermoelectric Coupling

“…The optical composite submarine cable will generate and transfer heat in the working state, and in the insulated state, the heat will also appear transient, so combined with the law of conservation of energy, this paper describes the heat transfer process of the optical composite submarine cable as follows [16].…”

Recent biomedical advancements in graphene oxide- and reduced graphene oxide-based nanocomposite nanocarriers

“…While GO and rGO nanoparticles can be incorporated into scaffolds for general tissue engineering, such as skin [ 188 – 190 ], cartilage [ 191 , 192 ], bone [ 189 , 193 – 195 ], and muscle tissue [ 196 , 197 ] rGO is commonly incorporated into nanofibers to enhance their electroconductivity, which is a significant factor in cardiac and nerve tissue regeneration [ 39 – 41 ]. Tissue engineering applications can also implement GO/rGO for morphological [ 198 ] and photoelectric [ 199 ] stimulations to encourage cell proliferation/differentiation.…”
