Phosphate-based glass fiber vs. bulk glass: Change in fiber optical response to probe in vitro glass reactivity
Abstract
This paper investigates the effect of fiber drawing on the thermal andstructural properties as well as on the glass reactivity of a phosphateglass in tris(hydroxymethyl)aminomethane-buffered (TRIS) solution andsimulated body fluid (SBF). The changes induced in the thermalproperties suggest that the fiber drawing process leads to a weakeningand probable re-orientation of the POPbonds. Whereas the fiber drawing did not significantly impact therelease of P and Ca, an increase in the release of Na into the solutionwas noticed. This was probably due to small structural reorientationsoccurring during the fiber drawing process and to a slight diffusion ofNa to the fiber surface. Both the powders from the bulk and the glassfibers formed a Ca–P surface layer when immersed in SBF and TRIS. Thelayer thickness was higher in the calcium and phosphate supersaturatedSBF than in TRIS. This paper for the first time presents the in vitroreactivity and optical response of a phosphate-based bioactive glass(PBG) fiber when immersed in SBF. The light intensity remained constantfor the first 48 h after which a decrease with three distinct slopes wasobserved: the first decrease between 48 and 200 h of immersion could becorrelated to the formation of the Ca–P layer at the fiber surface.After this a faster decrease in light transmission was observed from 200to ~ 425 h in SBF. SEM analysis suggested that after 200 h, the surfaceof the fiber was fully covered by a thin Ca–P layer which is likely toscatter light. For immersion times longer than ~ 425 h, the thickness ofthe Ca–P layer increased and thus acted as a barrier to the dissolutionprocess limiting further reduction in light transmission. The trackingof light transmission through the PBG fiber allowed monitoring of thefiber dissolution in vitro. These results are essential in developingnew bioactive fiber sensors that can be used to monitor bioresponse insitu.
