DIALYSIS-ASSISTED OPTICAL FIBRE SPECTROSCOPY PROBE

摘要

Dialysis assisted optical fibre probes (2), comprising a dialysis membrane (7) defining a sample volume (8); and at least one optical fibre (3, 4), for transmitting illumination to the sample volume (8) and receiving a spectroscopic signature of one or more analytes (16) within the sample volume. The dialysis assisted optical fibre probe (2) can be use to obtain the spectroscopic signature, e.g. fluorescence, absorption or Raman spectra, from a biological or chemical sample.
