Abstract

Catheter-sized absorbance sensors have been constructed and tested using the medically significant dye indocyanine green as an analyte. Sensors were found to be equally usable with conventional wavelength scanning instrumentation or with a very compact solid state instrument. Statistical evaluation of the data acquired with these small sensors showed that accurate working curves provide high sensitivity and wide dynamic range of use. Potential uses of these sensors are suggested.
