Abstract:
1. A photonic detection system comprising: a photonic membrane with through pores, the through pores having inner walls to which chemical or biological target specific anchors are adapted to be attached; an optical input to the photonic membrane; and an optical output detecting arrangement connected with the photonic membrane, wherein the through pores are distributed on the photonic membrane along multiple regions of through pores, through pores pertaining to a first region having inner walls to which a first type of chemical or biological target specific anchor is attached, through pores pertaining to a second region having inner walls to which a second type of chemical or biological target specific anchor is attached, and so on, wherein the photonic membrane comprises an additional region of through pores to which no chemical or biological target specific anchors are attached, and wherein measurement of a detection output of the photonic detection system occurs differentially, by subtraction of a detection output of the additional region of through pores from a detection output of each region of through pores.
