The effect of concentration of NaOH treatment on the performance of lateral flow assay (LFA) integrated with hydrolyzed electrospun PCL nanofibers for the detection of zika viral DNA. Qualitatively, the background or noise signals were stronger at test strips with electrospun PCL membrane treated with NaOH concentration beyond 1 M (A); The quantitative results for signal-to-noise ratio (SNR) showed the highest LOD at 0.5 nM for LFA with hydrolyzed electrospun PCL nanofibrous membrane treated with 1 M NaOH (B). n = 3. * represents p < 0.05.
