Micro Ring Resonators (MRRs) have become the workhorse in photonics, both for data/telecomas well as bio-chemical sensing applications. In this contribution the use of MRRs as sensors for food-safety applications will be discussed.

Human exposure to polybrominated diphenyl ethers (PBDEs) can occur via ingestion of indoor dust, inhalation of PBDE-contaminated air and dust-bound PBDEs. However, few studies have examined the pulmonary toxicity of particle-bound PBDEs, mainly due to the lack of an appropriate particle-cell exposure …
