Abstract
Optical techniques are considered as powerful tools for the development of chemical and biological sensors, covering a wide range of applications. Sensing techniques based upon the use of optical fibre devices to probe the optical characteristics of nanomaterials that exhibit changes in their optical properties upon exposure to targeted chemical species are particularly attractive, due to their potential high sensitivity, selectivity, the ready ability to multiplex arrays of sensors, and the prospect for remote sensing. The variety of different designs and measurement schemes that may be employed using optical fibres provides the potential to create very sensitive and selective measurement techniques that can be deployed in real environments. The use of optical fibre sensors is finding increasing acceptance across a range of industrial sectors, with interest being driven by features of the technology that offer advantages over conventional measurement approaches in niche applications. The presentation will discuss the development of fibre optic chemical sensors modified with the sensitive materials and introduce methods used for the deposition of the sensitive layers based on layer-by-layer adsorption and molecular imprinting techniques. Examples of the practical applications of the developed fibre-optic chemical sensors in bio-medical field will be provided.
