DEVELOPMENT OF AN INTEGRATED INDUCTIVE SENSOR FOR MAGNETIC IMMUNOASSAY IN LAB ON CHIP DEVICE
In this paper an inductive integrated sensor to be adopted in sensing application on microfluidic systems for biomedical applications is presented. It is based on the use of magnetic particles that suitably coated act as markers of the bio-molecule to be detected. The device consists of a primary coil and two secondary coils in a differential configuration. The sensing principle of the device is related to the output voltage variation on the secondary coils. This sensor will be embedded into a more general lab on a chip device in which suitable microfluidics will be implemented both to bind markers with analyte and to drive the fluid into the sensing chamber.
