Abstract

This study focuses on the influence of optical/imaging fiber surface characteristics and chemistry on bacterial attachment. Attachment profiles of medically significant and environmentally important bacteria on optical fibres, both as-received and eroded as a result of chemical etching, were evaluated. Bacterial cell characteristics such as surface charge and wettability were analyzed, together with optical fiber characteristics, such as surface chemistry, wettability, charge, surface tension and surface nano-roughness. A series of scanning electron microscopy (SEM), atomic force microscopy (AFM) and confocal laser scanning microscopy (CLSM) experiments were carried out to provide an insight into bacterial attachment behaviour on the optical surfaces. The results show that the as-received fiber surface was consistently more suitable for bacterial attachment than the modified surface. Therefore this study suggests that the surface treatment of optical fibers can be an important factor in the development of optical fiber sensors.
