Abstract
The modern internet-of-things era has witnessed an increasing growth in the demand for advanced sensors to collect precise information. To meet this demand, extensive efforts have been devoted to exploring competent materials and designing rational architectures for the fabrication of sensing devices. Graphdiyne represents a promising material due to the attractive electronic, optical and electrochemical properties deriving from its unique molecular structure. In this review, we firstly provide the points of view on the architectures and work principles of the graphdiyne-based sensing devices with respect to resistive, electrochemical, photoelectrochemical and fluorescent categories. Secondly, we present the promising applications on biochemical sensing, such as the detection of DNA, micro-RNA, and glucose. Finally, the challenges and prospects of graphdiyne-based biochemical sensing platforms are also discussed, in order to provide a cornerstone for understanding this rapidly developing area.
