A system for measuring the concentration of an assay substance comprising a sensor having an optical fiber (10) on one end of which is coated a body (22). A fluorophor is dispersed within the body (22), the fluorescent activity of which is altered in relationship to the concentration of the assay substance. Light from a source such as an LED (40) is carried by the fiber (10) to the body (22). Light emitted by the fluorophor is carried to a detector unit (54) along the fiber (10). Concentration of the assay substance is determined by measurement of the characteristics of the growth in emitted light following activation of the LED (40). |
