Researchers at Rensselaer Polytechnic Institute have developed thin, flexible energy storage devices consisting of more than 90 percent cellulose. The paper is infused with aligned carbon nanotubes (electrodes), and an electrolyte (e.g. an ionic liquid). The technology allows to fabricate batteries, supercapacitors, or devices which combine both functions. According to the press release, the devices can [...] QTL Biosystems announced that it is has been awarded a utility patent US 6,743,640 for a fluorescent polymer-QTL [Quencher-Tether-Ligand] approach to sensing target biological agents. [...] The platform utilizes changes in polymer fluorescence (polymer “superquenchingâ€) in the presence or absence of a target biological agent. The patented QTL bioconjugate enables quantitative detection of a diverse range [...] |
