ABSTRACT:
A process for indicator coating of SERS fiber-optic probes comprising selecting a potentially roughened probe which is enhanced with a deposited silver film and then treated by chemisorption on said probe to form a molecular-specific coating, such as by employing Eriochrome Black T for metal ions, octadecyl mercaptan for organics, or Cresol Red for pH.
