Lateral flow aptamer assay integrated smartphone-based portable device for simultaneous detection of multiple targets using upconversion nanoparticles

Simultaneous detection of multiple targets with different analyte-recognition reactions in the same sample in a rapid, low-cost and reliable way has immense potential with widespread applications in food safety, medical diagnostics and environmental monitoring. Herein, we developed a lateral flow aptamer assay (LFAA) integrated smartphone-based portable device for highly sensitive and precise detection of multiple targets, using aptamers...
