Abstract
The invention is a sensor which includes a porous microsphere and an optical fiber which having a proximal end and a distal end. The distal end of the optical fiber is coupled to the porous microsphere by an adhesive material. The porous microsphere is doped with a dopant. The dopant may be either an organic dye or an inorganic ion. A sensing apparatus includes the sensor, a spectrophotometer and a source of light. The spectrophotometer is coupled to the proximal end of the optical fiber. The source of light causes either the organic dye or the inorganic ion to fluoresce.
