One of the most serious problems relevant to the use of optical fiber sensors in real-world environments is surface fouling, that is, the cumulative build-up of undesirable material on the working surface of a sensor. This paper present the results of anti-biofouling tests on coated fiber optic probes for reflectance spectroscopy in blood- simulating foul media, namely Bovine Serum Albumin (BSA) and Fibrinogen. The anti-biofouling coating, a proprietary invention of Biocompatibles Ltd., was a cross-linkable Phosphorylcholine (PC) polymer with Silane functionality, to improve adhesion to silica-containing substrates. All tests in BSA and Fibrinogen showed that PC-1036 coating was efficient in avoiding the build-up of biological material. In fact, optical signal variations of un-coated probes showed fluctuations in the 6-20% range, while coated probes exhibited a nearly-stable optical signal. These results were also confirmed by a microscopic check, which showed adhesions of biological material to un-coated probes.
