Symposium on Surface Functionalization of Optical Fiber and Waveguide Based Bio- and Chemical-Sensors

Symposium Chair: Prof. Jacques Albert, Carleton University, Canada

The aim of this Symposium is to bring together chemists, biochemists, and photonic device designers to explore together how best to functionalize optical fiber devices to detect biochemical substances and chemicals with high sensitivity, selectivity, and robustness, while lowering the limit of detection to levels that will allow real applications to be developed.

The emphasis on the Keynote, Invited and Contributed talks will be placed on understanding and utilising the interface between the photons and the substances to be detected: specifically, understanding and optimising the transducing mechanism by which the presence of a molecular or biological agent results in a measurable change in the properties of the optical device (fibre, fibre grating and other waveguide technologies) and its reliability, reproducibility and robustness for both short and long term performance.  Of particular importance are issues regarding the refractive index, absorption and transmission, scattering and porosity, and thickness of the functional layers and how these parameters can be optimized to enhance the device response. Functionalization for bare glass and plastic surfaces, as well as for fibers with metal, special oxide or graphene coatings for Surface Plasmon Resonance (SPR) based sensors or metal-nanoparticle assisted devices, including quantised effects associated with quantum dots and excitons, will be discussed.
The Symposium itself will not on the other hand be a forum to present new sensor concepts or improvements of the optical underlying platform, or new sensing results with existing technological platforms - these are covered in the existing format of both BGPP and OS conferences.  We hope to have a lively exchange between those who practice the art of surface functionalization and those who are attempting to develop new devices and systems, potentially cross-fertilising and stimulating ideas between communities in what is becoming an increasingly important area of science and engineering.
