Evaluation of the NBC system for ZIKV detection. Sensitivity testing of the NBC system for ZIKV detection: (a) the change in bead motion magnitude in the presence of different concentrations of ZIKV (from 100 particles/μL to 106 particles/μL); (b) trajectory images of the motion of beads in the control sample and samples with different concentrations of ZIKV. Specificity testing of the NBC system for ZIKV detection: (c) the change in bead motion magnitude due to ZIKV and non-target viruses, including herpes simplex virus type 1 (HSV-1), human cytomegalovirus (HCMV), and dengue virus (DENV) types 1 and 2 were measured. The tested virus concentration for samples in the specificity evaluation was 106 particles/μL; (d) trajectory images of the motion of beads in the presence of ZIKV and other non-target viruses. Error bars are standard deviations from a total of three independent measurements.
