Application of nanoparticles for the diagnostic of spring viraemia of carp virus. a Unmodified gold nanoparticles (AuNPs) for the colorimetric detection of spring viraemia of carp virus (SVCV)-RNA (from Saleh et al. [52], figure subject to copyright and reproduced with permission from Springer Nature). Tube 1: Positive SVCV-RNA sample (blue color). Tube 2: No template control (red color). Each tube contained 5 μl of sample, 1.8 μM of primer and 0.1 M NaCl. b Serial dilution of SVC-RNA (Tubes 1 to 10 contain 105, 104, 103, 102, 10, 10–1, 10–2, 10–3 10–4 and 10–5 TCID50 ml − 1 SVC-RNA respectively) showing the sensitivity limit of the assay. The SVC-AuNPs assay could detect SVCV-RNA as far as the 10–3 TCID50 ml − 1 dilution (Tube 8; blue color)
