Abstract:
1. A method for detecting target antigens in a biological sample comprising: bonding a first set of antibodies to a plurality of biosample tracks deposited on a magnetic tape media; exposing the biological sample to the biosample tracks to allow the target antigens to bind to the first set of antibodies; bonding a second set of antibodies to magnetic nanoparticles; placing a solution of the second set of antibodies bonded to the nanoparticles on the biosample track to allow the second set of antibodies to bind to the antigens; rinsing the biosample tracks with water or a rinsing agent to remove any of the second set of antibodies not bound to the antigens; and scanning the tape media with a head module of a tape drive having a write-head and a magneto-resistive read sensor, wherein the write-head magnetizes the nanoparticles and the read sensor detects the magnetized nanoparticle in order to detect the antigens.
