Abstract
A method is provided for manufacturing a fiber optic sensor for detecting or measuring the concentration of carbon dioxide in a sample fluid. The method involves incorporation of a fluorescent indicator composition in a silicone capsule slidably arranged over the tip of a fiber optic, sealed with a suitable adhesive. To amplify the detectable signal obtained, the capsule is preferably fabricated so as to contain reflective particles, and tapers to a narrow tip. Novel optical sensors, manufactured using the aforementioned method, are provided as well.
