    Analysis of DDZ-AuNP sensitivity. A) DDZ-M-AuNP colorimetric assays were performed on DENV-2 NGC titers of 1 × 10 1 , 1 × 10 2 , 1 × 10 4 , and 1 × 10 6 to determine the limits of detection. Samples were assembled as described in Methods, incubated at 37°C for 30 minutes and photographed. Results show that the DDZ-M-AuNP colorimetric assay is capable of detecting DENV-2 at a titer as low as 1 × 10 1 . DDZ-M = anti-dengue virus DNAzyme, DDZin-M = inactive anti-dengue virus DNAzyme. B) Analysis of DDZ-AuNP sensitivity by UV/Vis spectrophotometry. Ten microliters (10 uL) of cell culture fluid from Mock, DENV-2 NGC (titers of 1 × 10 1 , 1 × 10 2 1 × 10 6 /mL), or CHIKV vaccine strain 181/25 (1 × 10 6/ mL) infected C6/36 cells, or DENV serially diluted from 1 × 10 1 (Dil1 through Dil5) or were added to separate mixtures as described in A) . UV/Vis spectrophotometric analysis was performed using the ND-1000 spectrophotometer at an absorbance of 520 nm. Absorbance measurements were graphed in log scale to illustrate sensitivity and accuracy of the colorimetric DENV detection method.

    Assessment of DDZ-AuNP specificity. A) DENV-2 and CHIKV (1 × 106/mL each) were placed in a buffered solution containing 10 mM MgCl2, 1 × 105 DDZ-AuNP particles/mL, 1.5 M NaCl, and 0.5% (w/v) SDS. Eppendorf tubes containing these mixes were incubated at 37°C for 30 minutes and photographed. CHIKV = chikungunya virus. DENV-2 = dengue virus serotype 2, DDZ-M = anti-dengue virus DNAzyme, DDZin-M = inactive anti-dengue virus DNAzyme. B) Analysis of DENV detection by UV/Vis Spectrophotometry. Samples were assembled as was performed for in A, mixed, incubated at 37°C for 5 minutes, and spectrophotometric analysis was performed using the ND-1000 spectrophotometer. C) Detection of DENV by DDZ-M-AuNP in comparison to several other flaviviruses. The specificity of our DDZ-M-AuNP device to detect DENV and not other fellow flavivirus members YFV, JEV or ZV was determined as described earlier (see Figure 4 ). D) An alignment was performed on consensus sequences of each of the four DENV serotypes to determine the most optimal regions for the design of serotype specific DDZ-AuNP devices by determining the region of least conservation one serotype has with the other DENV serotypes. E) Colorimetric serotype-specific detection of DENV. Cell culture supernatants from C6/36 cells mock infected (Mock), or from cells infected with either DENV serotypes 1 through 4 or CHIKV (1 × 106/mL each) were placed in buffered solutions containing the necessary cofactors and AuNPs tethered with our all purpose DENV serotype specific DNAzyme, DDZ-M, or one of the serotype-specific DDZs (designated DDZ-1 through-4) designed to specifically target the corresponding DENV serotype (Table 1 ). Eppendorf tubes containing these mixes were incubated at 37°C for 5 minutes and photographed.
