Biophotonics – Sensing
Photonic biosensing is an emerging multidisciplinary research area that is driven by the need for simple, fast and cost-effective diagnostic tools in the food and health sectors, in order to replace the complex, time consuming and expensive methods used today. Usually, photonic biosensors are nanophotonic devices fabricated in a variety of platforms (silica, silicon, silicon nitride, polymer) using high-volume production technology, which makes them very cheap and compact. As a result they are most suited for applications like lab-on-chip (LoC), e.g. for food safety and disease detection, especially in the developing world where laboratory infrastructure is difficult to access or unavailable, and optical coherence tomography (OCT), e.g. miniature OCT systems for low-cost medical imaging or non-destructive testing in industry.
