The Use of Crystalline Carbon-Based Nanomaterials (CBNs) in Various Biomedical Applications

Abstract

This review study aims to present, in a condensed manner, the significance of the use of crystalline carbon-based nanomaterials in biomedical applications. Crystalline carbon-based nanomaterials, encompassing graphene, graphene oxide, reduced graphene oxide, carbon nanotubes, and graphene quantum dots, have emerged as promising materials for the development of medical devices in various biomedical applications. These materials possess inorganic semiconducting attributes combined with organic π-π stacking features, allowing them to efficiently interact with biomolecules and present enhanced light responses. By harnessing these unique properties, carbon-based nanomaterials offer promising opportunities for future advancements in biomedicine. Recent studies have focused on the development of these nanomaterials for targeted drug delivery, cancer treatment, and biosensors. The conjugation and modification of carbon-based nanomaterials have led to significant advancements in a plethora of therapies and have addressed limitations in preclinical biomedical applications. Furthermore, the wide-ranging therapeutic advantages of carbon nanotubes have been thoroughly examined in the context of biomedical applications.

SiO2/SiC Nanowire Surfaces as a Candidate Biomaterial for Bone Regeneration

“…This observation can pave the way for the use of such core/shell nanowirebased biomaterials for applications such as the creation of scaffolds or membranes for bone regeneration due to their peculiar hydrophilicity, which is a fundamental aspect to be considered for cellular interactions. Moreover, it is important to underline that such results may have potential implications in a large number of biomedical implementations other than tissue engineering, such as for diagnostics, biosensor development, or drug delivery systems (for both prolonged release of drugs or targeted cancer therapy) [57]. The great advancements in the use of silicon-carbide-based biomaterials in biomedicine are fundamental as their hydrophilicity, besides all the other characteristics already discussed, is optimum for their use in contact with biological fluids and blood, leading to the overcome of many limitations of the actual surfaces.…”

Advances in Hole Transport Materials for Layered Casting Solar Cells

“…Graphene quantum dots (GQDs) or carbon dots are well known in optical applications, owing to their fluorescence and electrical properties, which are widely used as biomarkers and light emission materials [117][118][119]. GQDs are easily fabricated via hydrothermal, microwave-assisted, or solvothermal methods [119][120][121]. used a one-step acid treatment method to synthesize GQDs from carbon fibers, which were then employed as HTLs in OSCs [122].…”
