Abstract
A sensor apparatus includes a waveguide, a sensing layer, a light source for emitting light onto the waveguide, and a detector for detecting a wavelength transmitted from the waveguide. The sensing layer may include a polymer layer which may come into intimate contact with a sample matrix of the environment.

2 more elements
A sensor apparatus, comprising:
- a casing having a tubular body with a lengthwise opening;
- a waveguide having an incidence point and a transmission point;
- a sensing layer coupled to the waveguide, the sensing layer including a metal layer and a polymer layer, the metal layer being between the waveguide and the polymer lay;
- a light source positioned to emit light into the waveguide via the incidence point;
- a detector positioned to detect light from the waveguide via the transmission point;
- an objective between the light source and the incidence point, for focusing light from the light source onto the incidence point;
- and
- a second objective between the transmission point and the detector for focusing light from the transmission point onto the detector.
