Abstract:
Graphdiyne (GD), a new kind of two-dimensional carbon allotrope consisting of a hexagonal ring and a diacetylenic linkage unit, is observed to exhibit a high fluorescence quenching ability and can be used as a new platform for fluorescence sensing, where GD oxide, the oxidized form of GD, is found to exhibit higher quenching ability than GD. As a proof-of-concept demonstration, GD oxide is used to establish a new platform for effective fluorescence sensing of DNA and thrombin with a high sensitivity and selectivity.
