  • Direct detection of unamplified hepatitis C virus RNA using unmodified gold nanoparticles
    Patent number: 9303292
    Abstract: A gold nanoparticle-based colorimetric assay kit for hepatitis C virus RNA that detects unamplified HCV RNA in clinical specimens using unmodified AuNPs and oligotargeter polynucleotides that bind to HCV RNA. A method for detecting hepatitis C virus comprising contacting a sample suspected of containing hepatitis C virus with a polynucleotide that binds to hepatitis C virus RNA and with gold nanoparticles, detecting the aggregation of nanoparticles, and detecting hepatitis C virus in the sample when the nanoparticles aggregate (solution color becomes blue) in comparison with a control or a negative sample not containing the virus when nanoparticles do not aggregate (solution color remains red).
