Abstract
Nanotube based lateral flow test device described herein is a lateral flow based diagnostic device, which uses arrays of fragments of single wall carbon nanotubes as sensor to detect the biomarkers at ultralow concentration (below picogram per milliliter). The device is consisted of the following components: (1). an lateral flow strip which typically is consisted of a backing film laminated with conjugate/sample pads, nitrocellulose membrane, wicking pad, (2). the arrays of single wall carbon nanotube conjugate with antibody which is immobilized on the membrane of the lateral flow device as the test line, (3). pairs of micro-electrode are installed on top part of the cassette, (4). a cassette which holds the lateral flow strip. The device can be used in clinical environments for biomarker detection.
