▎ 摘　　要

Graphene-based FRET aptasensors can be realized only by unique combinations of aptamer that can be freely functionalized by chemical modification, and graphene/graphene oxide that works as an excellent fluorescence acceptor at the same time as aptamer adsorbates. This review describes the principles of the sensor, several applications to microchannel devices, improvement of the sensing performance by molecular design of the aptamer and remarks on future prospects based on an introduction of recent works and achievements, including the author's paper. The sensor employs DNA modified with graphene/graphene oxide at the terminal as the molecular probe. This system is supported by the excellent property of DNA that does not lose the molecular recognition ability even due to a chemical modification at the terminal. I hope that this review will be useful for developing research on higher performance of graphene aptasensors in the future.
