Abstract
Photonic detection systems and methods are shown. A flow through photonic membrane is provided with pores which are distributed along multiple regions. The pores of one region have walls to which a first type of target specific anchor can be attached, while pores of another region have walls to which a second type of target specific anchor can be attached. An additional region of pores without anchors can be provided, so that optical detection occurs differentially. A stack of photonic membranes is also provided. The diameter of the pores of one photonic membrane is larger than the diameter of the pores of another photonic membrane, thus allowing also determination of the size of a target organism flown through the stack of membranes.
