Reports from Tsinghua University Describe Recent Advances in Fullerenes

May 27, 2014



By a News Reporter-Staff News Editor at Life Science Weekly -- Data detailed on Fullerenes have been presented. According to news reporting originating from Beijing, People's Republic of China, by NewsRx correspondents, research stated, "The one-dimensional pi-conjugated structure endows carbon nanotube (CNT) with large specific surface area and excellent photophysical properties, thus providing a unique platform for the development of chemo- and biosensors based on optical signal output. Although CNT acts as an optical signal transducer, it does not own any intrinsic ability for the selective binding and recognition of analytes."

Our news editors obtained a quote from the research from Tsinghua University, "Thus, hybridization of CNTs with functional components that specifically recognize various chemical and biomolecular analytes is often necessary in the preparation of CNT-based sensors. In this review, we summarize preparation and photophysical properties of CNT-based composites, and then highlight on fluorescence sensors based on CNT-composites. These composite sensors integrate the signal transduction property of CNT and the recognition properties of the hybridized functional components. The functional components selectively bind with the target analytes, whereas, CNTs transform the binding events into output signals detectable using spectrofluorometer."

According to the news editors, the research concluded: "Particularly, we highlight on recent progress in the chemical and bimolecular sensors based on near-infrared fluorescence of semiconducting single-walled CNT (SWCNT) and the excellent fluorescence quenching ability of CNTs over conventional organic quenchers."
