Abstract
Embodiments of the present invention provide a lateral flow assay method and strip wherein a sample is injected into a sample pad, a preconcentration kit is coupled to the sample pad to preconcentrate analytes, and a conjugate pad or a test pad is connected to the sample pad to transfer the analytes to the conjugate pad or the test pad, whereby a biomarker present at a low concentration can be detected.
Claims14
A lateral flow assay strip for detecting analytes in a sample, the lateral flow assay strip comprising:
- a support;
- a sample pad supported by the support and receiving the sample;
- a preconcentration kit supported by the support, the preconcentration kit comprising at least one selective ion permeable membrane, and electrodes connected to the at least one selective ion permeable membrane;
- and
- a test pad supported by the support and comprising a at least one captor for capturing the analytes.
