Abstract: In one example in accordance with the present disclosure, a fluorescence detection system is described. The fluorescence detection system includes a microfluidic chamber to receive a sample containing a compound to be detected. The system also includes a light guide, a portion of which is adjacent the microfluidic chamber. The light guide refracts excitation light into the microfluidic chamber to excite fluorophores in the microfluidic chamber. The light guide has total internal reflection in those portions that are not adjacent the microfluidic chamber. The fluorescence detection system also includes a heating element to trigger a reaction in the microfluidic chamber, an illumination source to provide the excitation, and a detection system to detect fluorescence generated by the excitation of the fluorophores in the microfluidic chamber.

Abstract: A pyrogenicity test method and assay of endotoxins allows for rapid and ultrahigh sensitivity testing of parenteral pharmaceuticals or medical devices that contact blood or cerebrospinal fluid by employing a Limulus Amoebocyte Lysate (LAL) assay monitored with a photonic-crystal biosensor. The photonic-crystal biosensor is capable of determining the presence of endotoxins in a test sample by detecting shifts in the resonant condition of an open microcavity affected by the changes in the refractive index of the analyte solutions used.
