Studies from Institute of Metal Research Yield New Information about Fullerenes

June 18, 2014

By a News Reporter-Staff News Editor at Biotech Week -- Investigators discuss new findings in Fullerenes. According to news reporting out of Shenyang, People's Republic of China, by NewsRx editors, research stated, "We developed a simple and scalable selective synthesis method of high-quality, highly concentrated semiconducting single-wall carbon nanotubes (s-SWCNTs) by in situ hydrogen etching. Samples containing ~93% s-SWCNTs were obtained in bulk."

Our news journalists obtained a quote from the research from the Institute of Metal Research, "These s-SWCNTs with good structural integrity showed a high oxidation resistance temperature of ~800 C. Thin-film transistors based on the s-SWCNTs demonstrated a high carrier mobility of 21.1 cm(2) V(-1) s(-1) at an on/off ratio of 1.1 x 10(4) and a high on/off ratio of 4.0 x 10(5) with a carrier mobility of 7.0 cm(2) V(-1) s(-1)."

According to the news editors, the research concluded: "A biosensor fabricated using the s-SWCNTs had a very low dopamine detection limit of 10(-18) mol/L at room temperature."
