3D Micro-solenoid for High Sensitivity Antibody Detection for Infection Testing

This paper is on developing three-dimensional micro-solenoids with channels through which magnetically tagged antibodies can flow through for the purposes of antibody detection for viral infections. A COMSOL simulation study has been conducted and a 3D-printed micro-coil winding apparatus has been designed and fabricated for automating the coil-winding process. An ultra low-noise amplifier circuit is simulated, prototyped and tested for the purpose of amplifying the induced voltages from the micro-solenoid when a magnetically tagged antibody passes through.
