Aptamer-Based Lateral Flow Biosensor for Rapid Detection of Salivary Cortisol [PDF]
ACS Omega, 2020 We have developed a disposable point-of-care (POC) aptamer-based biosensor for the detection of salivary cortisol. Nonstressful and noninvasive sampling of saliva compared to that of blood makes saliva an attractive biological matrix in developing POC devices for biomarker monitoring. Aptamers are attractive as recognition elements for multiple reasons,

Fluorescent carbon nanoparticle-based lateral flow biosensor for ultrasensitive detection of DNA. [PDF]
Biosens Bioelectron, 2017 We report a fluorescent carbon nanoparticle (FCN)-based lateral flow biosensor for ultrasensitive detection of DNA. Fluorescent carbon nanoparticle with a diameter of around 15nm was used as a tag to label a detection DNA probe, which was complementary with the part of target DNA. A capture DNA probe was immobilized on the test zone of the lateral flow
