To meet the highly demanding challenge for detecting protein biomarkers at pg/mL level in highprotein sera sample, the coupling of paramagnetic nanoparticle technology with aptamer-PQC biosensor was attempted for developing aptamer-PQC biosensor for selective detection of SCV helicase protein produced from SARS CoV replication. The coupling of aptamer coated paramagnetic nanoparticles for sample pretreatment to aptamer-PQC biosensor has shown to detect helicase protein in one-minute assay with a detection limit of 3.5 ng/mL. The aptamer-coated crystal exhibits a frequency shift linearly proportional to the concentration of SARS helicase from 0.05 to 1 μg/mL with...
