Abstract
Tubing such as clear plastic disposable tubing or glass tubing includes a photonic sensor formed in or placed within the tubing. The photonic sensors can take the form of photonic crystal sensors, distributed feedback laser sensors, and surface enhanced Raman spectroscopy (SERS) sensors, including photonic crystal enhanced SERS sensors. Detection arrangements for the sensors are described. The invention has many applications including tubing used in hospital care (e.g., urinary catheters, intravenous fluid delivery tubing, tubing used in dialysis, e.g. heparin lines or blood tubing sets), food manufacturing, pharmaceutical manufacturing, water quality monitoring, and environmental monitoring.
