Ultrasensitive Detection of Porcine Epidemic Diarrhea Virus Infections Using Multivalent DNA Nanostructure‐Enabled Lateral Flow Assay

Advanced Healthcare Materials, EarlyView.
A multivalent DNA nanostructure‐enabled lateral flow assay was developed for rapid, ultrasensitive detection of porcine epidemic diarrhea virus (PEDV) nucleocapsid protein. Designer net‐shaped DNA nanostructures (DNA‐Net) presenting PEDV‐specific aptamers achieved ~1000‐fold enhanced binding, enabling detection of viral copies with Ct ≤ 37.42 within 10

Limit of detection (LOD).

, 2020
Replicate testing of serial dilutions of HIV-2 NIH-Z isolate in BaseMatrix performed over three (3) assay runs (9 replicates total) were used to calculate the LOD at 95% (79 copies/ml) and 50% (16 copies/ml) confidence limits.
