摘要
A gold nanoparticle-based colorimetric assay kit for nucleic acids from viral, bacterial and other microorganisms that detects unamplified or amplified polynucleotides in clinical specimens using unmodified AuNPs and oligotargeter polynucleotides that bind to a pathogen's nucleic acids. A method for detecting a pathogen comprising contacting a sample suspected of containing microbes with a polynucleotide that binds to pathogen nucleic acid and with gold nanoparticles, detecting the aggregation of nanoparticles, and detecting pathogen polynucleotides 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).
