Fig. 2From: Development of a new method based on unmodified gold nanoparticles and peptide nucleic acids for detecting bovine viral diarrhea virus-RNATEM images of AuNPs in the presence of positive and negative samples. RNA of positive sample inhibits PNA induced aggregation of AuNPs (a) while AuNPs are aggregated in presence of PNA and negative sample RNA (b)Back to article page
