An improved modeling system and associated techniques are described herein. The probes contain scissile linkages that are cleaved by enzymes when hybridized to a target, yielding detectable probe fragments free of the target. At the same time the polymer-based material may be cured or otherwise solidified to affix the conductive path formed by the magnetic material particles. The supporting portion is configured to support the antenna to be slidable between the first position where the antenna is inside the housing and the second position where the antenna is out of the housing, and also to be pivotable at the second position.
