Abstract excerpt

A rapid label-free visual assay for the detection of viral RNA using peptide nucleic acid (PNA) probes and gold nanoparticles (AuNPs) is presented in this study. Diagnosis is a crucial step for the molecular surveillance of diseases, and a rapid visual test with high specificity could play a vital role in the management of viral diseases. In this assay, the specific agglomerative behavior of PNA with gold...
