1. A sensor for detecting one or more analytes, comprising:
a porous planar substrate having a plurality of regions, and a second region including a second photoluminescent structure different from a first photoluminescent nanostructure; and
at least one photoluminescent nanostructure on or embedded within the sensor porous planar substrate in a first region, and a second photoluminescent structure different from the first photoluminescent nanostructure in a second region.
