A sensor made of porous matrix or sol-gel glass and non-enzymatic macromolecular polymer immobilized in the sol-gel glass. The macromolecule is physically entangled or otherwise trapped, and does not leach regardless of exposure to elevated temperature and pressure. Surface effects are minimized since the there is no chemical bond between macromolecules and sol-gel glass. Indicator molecules may be attached to the macromolecular polymer either before or after the macromolecule is incorporated into the porous matrix. |
