A method is provided for manufacturing a fiber optic sensor for detecting or measuring a parameter of interest in a sample fluid, including pH, concentration of dissolved gases such as O.sub.2 or CO.sub.2, and the like. The sensing chemistry is affixed to the distal end of an elongated optical fiber by way of an adhesive layer typically comprised of an acrylic adhesive composition. Novel optical sensors, fabricated using the aforementioned method, are provided as well.
