Abstract

Abstract An article comprising a solid substrate, in particular an optical fiber, to the surface of which are attached a plurality of polymer molecules, the polymer molecules embodying a multiplicity of chemically, biochemically or biologically active species. A method of preparing an optical fiber which is useful for sensing a chemical or physiological parameter of a body fluid or tissue (a) comprises providing an optical fiber having a distal end, and (b) treating the distal end of the fiber to attach to it a polymer embodying a multiplicity of molecular species which are capable of sensing the desired parameter.
