Label-Free Plasmonic Immunosensing for Plasmodium in a Whole Blood Lysate

In this paper, we report an experimental demonstration of malaria pathogen detection in a whole blood lysate using plasmonic nanostructures. The plasmon sensor utilizes extraordinary optical transmission through a nanostructure to directly probe antibody-antigen interactions. The measured refractive index sensitivity of the nanostructured sensor is 378 nm… CONTINUE READING
