An improved optical sensor and methods for measuring the presence of various materials or constituents in a fluid sample uses reactive material(s) in a fluid environment. The reactive materials have optical properties that change in the presence of a target material that may be present in the environment. An optical emitter generates light that is directed to the reactive materials, and one or more optical detectors receive reflected light from one or more interfaces in the optical path between the emitter and the detector(s), one or more of the interfaces having a reactive material. The reactive material(s), emitter(s), and detector(s) are selected based on the desired target material to be sensed.

Optical sensor with chemically reactive surface

An improved optical sensor and methods for measuring the presence of various materials or constituents in a fluid sample uses one or more reactive materials in a fluid environment. The reactive materials have optical properties that change in the presence of one or more target materials that may be present in the environment. One or more optical emitters generate light that is directed to the reactive material(s), and one or more optical detectors receive light from the reactive material(s), and the presence or absence of the target material is determined based on the light received at the optical detector(s). The reactive material(s), emitter(s), and detector(s) are selected based on the desired target material to be sensed.
