  • Patent number: 11268967
    Abstract: The present invention discloses a diagnostic device or kit for visual detection of bilirubin. Said diagnostic device or kit comprises chitosan stabilized gold nanoclusters based luminescence source, Cu2+ ions source for quenching luminescence intensity of said gold nanoclusters and recovery of quenched luminescence intensity in the presence of bilirubin. The said device enables non-invasive detection of hyper-bilirubinemia by thumb impression visually or from blood serum.
    Type: Grant
    Filed: June 2, 2016
    Date of Patent: March 8, 2022
    Assignee: INDIAN INSTITUTE OF TECHNOLOGY, GUWAHATI

  • Patent number: 6833162
    Abstract: A process for generating colored nanolithography patterns of parallel lines or cross pattern lines on a glass or plastic substrate, said process consisting the steps of pressing a polycarbonate or aluminium mold obtained from a compact disk on a glass or plastic surface inked with a permanent marker ink for one or more times to create lithographic patterns of parallel colored lines or cross pattern lines. Also, the present invention provides a method for generating colored nanolithography patterns of parallel lines or cross pattern lines on a glass or plastic substrate having dried ink, said process consisting keeping the plastic or glass substrate having the dried ink in a chamber containg ethanol or toluene for about 10 seconds followed by pressing the polycarbonate or aluminium mold obtained from a compact disk on the glass or plastic surface to generate the pattern.
