Figure 6From: A signal amplification assay for HSV type 1 viral DNA detection using nanoparticles and direct acoustic profilingConcentration vs frequency change plot for VP16 target hybridization to VP16 surface probe. White: Heterogeneous assay with signal enhancement using NA. Light grey: Semi-homogeneous assay with signal enhancement with NA. Dark grey: Homogeneous assay and with 15 nm NA modified Au nanoparticles. Error bars represent standard deviations for n = 4.Back to article page
