External cavity laser label-free biosensor
… cavity laser, we demonstrate a new type of label-free optical biosensor that achieves a high quality factor through the process of stimulated emission, while at the same time providing high sensitivity, large dynamic range and simple detection instrumentation. The photonic crystal is …

Label-free biosensor based upon a vertically emitting distributed feedback laser
… state organic distributed feedback laser (DFB) biosensors. The combined techniques enable the organic DFB laser to be uniformly fabricated over large surface areas upon a flexible plastic substrate, with an approach that is compatible with roll-based manufacturing. Secondly, laser pump threshold …

Label-Free Biosensor Based Upon Replica-Molded Vertically Emitting Distributed Feedback Laser
The DFB laser sensor represents a departure from conventional passive resonant sensors insofar as the device actively generates its own narrowband high-intensity output without stringent requirements on the coupling alignments resulting in a simple, robust illumination and detection configuration. …

Using photonic crystal biosensors for pharmaceutical screening
The application of photonic crystal surfaces for label-free bioimaging and sensing is presented. A label-free biosensor assay is used to monitor the density of cell attachment to the sensor surface, and to quantify changes in attached cell density induced by the introduction of plant extracts. This …

Development of label-free colorimetric plasmonic sensor for biomedical applications
Biosensor technology is making strides due to its association with detection and quantification of a wide array of physiological profile makers, biomarkers, for the early detection of diseases. The newest technologies encompasses both qualitative as well as quantitative measurement of such markers. …

Application of silicon photonic microring resonators to the study of surface bioconjugation and protein capture agent binding kinetics
… binding and detection in an array-based, label-free biosensor format. First, aniline-catalyzed hydrazone ligation between surface immobilized hydrazines and aldehyde-modified antibodies is shown to be an efficient method to functionalize model oxide-coated sensor substrates with protein …

A systematic study of ion-induced nanopatterning on photonic crystal-based label-free optical biosensor
Photonic crystal (PC)-based biosensors are promising candidates for label-based fluorescence and label-free optical biosensors. This is due to the presence of PC, a periodically-structured dielectric material with diffraction gratings engineered on the surface that can control light propagation …
