(A) Magnetic bead-quantum dot (MB-QD) conjugate. (B) Magnetic bead-quantum dot (MB-QD) assay for capture and detection of Plasmodium falciparum histidine-rich protein 2 (HRP2). The MB-Ab conjugates are incubated with HRP2 antigens for capture and after washing are then incubated with QD-Ab conjugates for detection. (C) MB-QD assay for detection of HRP2. Fluorescence intensity for detection of 1–60 ng (33–2,000 ng/mL) HRP2 in 30 μL of normal human serum. Similar results were obtained using 1 mL of human urine. The insert shows the photoluminescence spectra for one experiment. All measurements were performed in triplicate. Error bars represent standard deviation.
