  • Water soluble polymer surfactant for synthesis of functionalized polystyrene nanobeads towards detection of bilirubin in human serum
    Patent number: 11719709
    Abstract: The present invention provides a water soluble polymer surfactant (PS-DGlu) of formula I which is utilized for synthesis of functionalized polystyrene nanobead covalently incorporating (oligo) p-phenylenevinylene (OPV) nanosensor (PSG-OPV-n) which in turn is useful for the detection of bilirubin in human serum. The present invention further provides a process for the preparation of the water soluble polymer surfactant (PS-DGlu) of formula (I) and a mini emulsion polymerization process for the synthesis of PSG-OPV-n. wherein, n is 30-50. The PSG-OPV-n nanosensor beads show selectivity towards detection of bilirubin in presence of interferences such as glucose, sucrose, metal ions, cholesterol, and biliverdin with limit of detection of 20 nM. Ultimately, the invention also provides a kit for visual detection of bilirubin in human serum.
