Claim Text:
1. An electromagnetic effect field detection system for measuring labels in a fluid comprising: a planar substrate; at least one electromagnetic effect field sensor formed on a first surface of said planar substrate; a backing structure substantially supporting a second surface of said planar substrate where said second surface is on the opposite side of said planar substrate from said electromagnetic effect field sensor; a flow permeable membrane supported substantially on said first surface of said planar substrate and covering said at least one electromagnetic effect field sensor; wherein a thinnest dimension of said flow permeable membrane is perpendicular to said first surface of said planar substrate; wherein a length and width of said flow permeable membrane are parallel to said first surface of said planar substrate; one or more sensing lanes, each lane comprising; a continuous flow path and intended flow direction through interconnected pores of said flow permeable membrane, said continuous flow path being substantially parallel to the length of said flow permeable membrane, one or more label detection zones, where said label detection zones are disposed within said flow permeable membrane and positioned directly above said electromagnetic effect field sensor; where the surface area of said flow permeable membrane is greater than that of said planar substrate; wherein said continuous flow path further comprises features that divert flow by plugging some of said pores in said flow permeable membrane; a first set of one or more electrical interconnects.
