Graphene materials-based energy acceptor systems and sensors

Publication date: March 2014 Source:Journal of Photochemistry and Photobiology C: Photochemistry Reviews, Volume 18 Author(s): Zhen Li , Mengyuan He , Dangdang Xu , Zhihong Liu Graphene materials have recently attracted considerable attention because of its extraordinary mechanical, electronic, thermal and optical properties, leading to the wide application of graphene such as in biology and energy areas. In recent years, energy-transfer based optical biosensors using graphene materials as the energy acceptors have become the focus of researches, which take the advantages of the high surface area and ultrahigh luminescence quenching efficiency of graphene materials. These sensors have extensively covered the detection of DNA, protein, enzyme activity, metal ions and other small molecules. In this review article, we aim to provide a comprehensive discussion on the development of the graphene materials-based energy acceptor systems and sensors, sorting the sensors according to the probes with which the energy acceptors are assembled to or conjugated with the luminescent energy donors. At the end we also present an overview of future perspective and possible challenges in this rapidly developing area. Graphical abstract
