Optical fiber coatings

Fig. 18.2. Biosensor scheme describing the various steps involved in the immunoassay using ITO-poly(pyrrole-biotin)-coated optical fibers for the detection of anti-cholera toxin B subunit using the biotin-avidin immobilization technique.

Fig. 18.5. Calibration curve obtained by the immunoassay procedure for the detection of anti-CTB using the ITO-PPB-coated optical fibers. The curve was fitted according to the equation y = A+B ln(.r), where x is the anti-CTB dilution value and y is the chemiluminescence response. The obtained correlation coefficient is R2 = 0.95.

Such a procedure was successfully applied to poly(THF) leading to novel fluorinated telechelic diols precursor of a, co-diacrylates useful for coating optical fibers [13] ...

Fig. 2 - The specificity of binding of the fluorescent probe to the Ab-coated optic fibers of the biosensor, (left) The fluorescent signal transmitted by quartz fibers coated with mAbs raised against BE, compared to that of untreated fibers and fibers coated with human IgG or casein. The flow buffer contained 10 nM FL-BE. The lines are offset from each other by 10 mV. Reproduced with permission from reference 4 Copyright 1995 American Chemical Society, (right) The fluorescence transmitted by TCPB-FL, bound to the fiber coated with rabbit anti-PCB IgGs, control rabbit IgG, human IgG or casein compared to a bare fiber. It is clear that the non-specific TCPB-FL binding to the quartz fibers, non-target IgG can be significant and must be corrected for.

Wang and Cheng reported preparation of ultraviolet light-curable resin for coating optical fibers. It consists of polydimethylsiloxane epoxy acrylate and polyethylene glycol urethane acrylate. To this were added in different proportions trimethylolpropane triacrylate to modify the properties of blends. After addition of a photoinitiator the choice formulation photo cured in 5 seconds. 

Characterization and evaluation of performance by means of the torsional pendulum technique has been discussed by Hussain Wierenga et al. have used ultramicro indentation measurements for the determination of the viscoelastic properties of coated optical fibers... 

Low viscosity materials with good dielectric properties and very low Ionic contamination which can be cured by a variety of mechanisms form the basis for a broad family of electronic coatings, encapsulants, sealants and adhesives. Systems of this type which can be cured very rapidly (<1 second) [26] are Important for coating optical fibers.
