Tissue engineering, by combining different fields such as physics, nanotechnology, molecular biology and evolution, on the one hand, tries to provide a more complete and better understanding of cellular processes, and on the other hand, to improve engineering methods and tissue production. Alternatives for medical use. Nanotechnology, meanwhile, has led to significant advances in the development of new materials for use in the biomedical field. Nanomaterials with the aim of facilitating the creation of tissue engineering structures have the ability to be designed to create the least inflammatory response in the host body. Therefore, knowledge of the impact of these properties on cell behavior is essential, both in early cell research and in application-related areas, such as tissue engineering and cell-based technologies. Biomaterials with a high surface-to-volume ratio contribute significantly to the adsorption capacity and chemical activity, which ultimately leads to increased cellular function. Also, biological nanomaterials, compared to conventional conventional biomaterials, have a high potential for loading drugs and nucleic acids or other biological factors to accelerate tissue repair and regeneration. This paper reviews the applications of biomaterials in tissue engineering and regenerative medicine and discusses the role of these materials as additives in tissue engineering scaffolds as well as induction factors in the culture medium.

Due to advanced and stable physical, chemical, and optical properties, low-toxicity and high-biocompatibility, carbon quantum dots have attracted significant attention
for employment in bioimaging, biomedicine and therapeutics. Although several studies have focused on improving the major properties of these semiconducting quantum dots, there are still a lot more investigations required to make them reliable agents for biological applications. In this paper, characteristics, applications and synthesis methods of graphene quantum dots have been introduced.
