APTEC: aptamer-tethered enzyme capture as a novel rapid diagnostic test for malaria†
Abstract
We report the rapid diagnosis of malaria by aptamer-tethered enzyme capture (APTEC) whereby an aptamer captures biomarker Plasmodium falciparum lactate dehydrogenase (PfLDH) then activity is measured colorimetrically. The robust test was sensitive (limit of detection = 4.9 ng mL−1) and could reliably diagnose malaria in clinical blood samples.
