Claim 0:
1. A device comprising:
an elongated body defining a lumen, the elongated body comprising:
a proximal portion and a distal portion; and
an opening in fluid communication with the lumen, wherein the opening is configured to receive a plurality of microbeads coated with a fluorescent material; and

one or more sensors configured to:
stimulate a fluorescence response from the plurality of microbeads released into a fluid and flowing with the fluid through the lumen; and
detect the fluorescence response, wherein the fluorescence response is indicative of a composition of the fluid,

wherein the one or more sensors comprise:
a light source configured to emit light into the fluid flowing in the lumen to expose the plurality of microbeads to the emitted light; and
a light detector configured to detect the fluorescence response of the plurality of microbeads.
