Patent attributes
The subject invention provides materials and methods for detecting Zika virus. Specific embodiments provide an electrochemical immunosensing device and the methods of making and using the same for detecting Zika virus with exceptionally low detection limit. In some embodiments, the immunosensing device is capable of detecting picomolar (pM) level of Zika virus present in a sample by employing immunosensors functionalized with Zika virus binding ligands such as monoclonal Zika virus antibodies and Zika non-structural proteins. In an exemplary embodiment, the immunosensing device can be integrated with microelectronics to be adopted as point-of-care sensing systems. Advantageously, technologies provided herein offer rapid, on-site biosensing methods for the accurate detection of diseases caused by Zika virus.
