Abstract

Scaffolds are physical substrates for cell attachments, proliferation, and differentiation, ultimately leading to tissue regeneration. Current literature validates tissue engineering as an emerging tool for bone regeneration. Three-dimensionally printed natural and synthetic biomaterials have been traditionally used for tissue engineering. In recent times, graphene and its derivatives are potentially employed for constructing bone tissue engineering scaffolds because of their osteogenic and regenerative properties. Graphene is a synthetic atomic layer of graphite with SP2 bonded carbon atoms that are arranged in a honeycomb lattice structure. Graphene can be combined with natural and synthetic biomaterials to enhance the osteogenic potential and mechanical strength of tissue engineering scaffolds. The objective of this review is to focus on the most recent studies that attempted to explore the salient features of graphene and its derivatives. Perhaps, a thorough understanding of the material science can potentiate researchers to use this novel substitute to enhance the osteogenic and biological properties of scaffold materials that are routinely used for bone tissue engineering.

摘要

支架是细胞附着、增殖和分化的物理基质,最终导致组织再生。当前文献证实组织工程是一种新兴的骨再生工具。三维打印的天然和合成生物材料传统上一直用于组织工程。近年来,石墨烯及其衍生物因其成骨和再生特性而被潜在地用于构建骨组织工程支架。石墨烯是一种由SP2键合碳原子组成的石墨合成原子层,这些碳原子排列成蜂窝晶格结构。石墨烯可以与天然和合成生物材料结合,以增强组织工程支架的成骨潜力和机械强度。本综述的目的是关注最近试图探索石墨烯及其衍生物显著特征的研究。也许,对材料科学的深入理解可以促使研究人员使用这种新型替代品来增强常规用于骨组织工程的支架材料的成骨和生物学特性。
