Abstract
A method for the functionalization of surfaces within soft glass microstructured
optical fibers has been developed, using self assembled monolayers (SAMs)
of silane coupling agents. We demonstrate the use of measurements of the fiber
capillary fill rate, as a positive test for a functionalized internal surface.
A simple theoretical model is used for comparison with measured fill rates.
During this work, adsorption kinetics for SAMs of octadecyltrichlororsilane
onto lead silicate glass has been investigated. This work is a critically
important first step for a plethora of applications in biophotonics, chemical
fiber sensing as well offering promise for protecting fiber glass from degradation.
