Abstract
Atomically-thin two-dimensional (2D) nanostructure, an emerging class of nanomaterials, has achieved tremendous progress in the past decade and will remain a significant research topic in the near future. Apart from the discoveries of various 2D nanomaterials, remarkable attentions have been paid to the rational design and alteration of architectures based on pristine 2D materials to meet demands of next-generation functional applications in the near term. Herein, this review intends to provide an instant survey over the recent key advances on the structural engineering strategies of 2D nanomaterial-based architectures for new sensing capabilities and opportunities. Through intrinsic or extrinsic alterations, the pristine 2D nanostructures of some unique intrinsic properties could be modified and functionalized to overcome existing drawbacks and obtain synergistic abilities, demonstrating a great potential in promoting sensing performances. In parallel with the latest development of structural engineering strategies and related functionalized devices including sensors towards detecting Covid-19 antigens, the underlying mechanisms are reviewed to offer insights in understandings of architecture design and property tailoring for boosting sensing capabilities and performances.
