their excellent mechanical properties. In spite of their higher Young’s modulus, the

energy required to expand, bend, and shear them is very low due to their thickness of

one or fewer atoms [29]. Consequently, 2D materials possess higher strength as well as

good flexibility at the same time. Such materials are highly compatible with the de­

velopment of bioelectronics that could connect and follow movements of body tissues.

3.3 Synthesis of 2D Materials for Bioelectronics

The performance of 2D material for bioelectronics significantly depends on its synthesis

protocol. Numerous synthesis protocols have been proposed to prepare a variety of 2D

materials. In contrast, 2D materials are prepared by two most common synthesis proto­

cols, i.e., top-down and bottom-up approaches. Herein, recent advances and drawbacks

of synthesis approaches are addressed.
