Abstract:

This presentation introduces an architecture for a portable system based on a magnetoresistive biochip microarray for DNA recognition or microorganism/cell identification. In this biochip, biological targets are labeled with magnetic nanoparticles which are used to guide target over surface immobilized probes. Furthermore, the magnetic stray field created by those labels is detected by on-chip magnetic resistive sensors providing target and probe molecular recognition.

The architecture is proposed for developing a biochip platform that incorporates electronics for addressing, reading out, sensing and controlling temperature and in addition a handheld analyzer capable of multiparameter identification. The biochip platform can be plugged in a peripheric standard bus of the analyzer device or communicate through a wireless channel.
