Fiber-optic biosensors – an overview
Analytical and Bioanalytical Chemistry, 2002This article reviews progress and developments during the past five years in the field of optical fiber biosensors. Because of the expense and time constraints associated with modern laboratory analysis, there is a growing need for real-time, low-cost technology that can be used industrially, environmentally, and clinically, and to monitor food ...

Receptor heterogeneity in optical biosensors
Journal of Mathematical Biology, 2017Scientists measure rate constants associated with biochemical reactions in an optical biosensor-an instrument in which ligand molecules are convected through a flow cell over a surface to which receptors are immobilized. We quantify transport effects on such reactions by modeling the associated convection-diffusion equation with a reaction boundary ...

Optical biosensors for cell adhesion
Journal of Receptors and Signal Transduction, 2009Planar optical waveguides offer an ideal substratum for cells on which to reside. The materials from which the waveguides are made--high refractive index transparent dielectrics--correspond to the coatings of medical implants (e.g., the oxides of niobium, tantalum, and titanium) or the high molecular weight polymers used for culture flasks (e.g ...

A Fiber-Optic Cocaine Biosensor
Analytical Biochemistry, 1995A fiber-optic biosensor was developed for detection of cocaine, its metabolites, and other coca alkaloids, using a monoclonal antibody (mAb) against a derivatized benzoylecgonine (BE). The mAb was immobilized noncovalently on quartz fibers and a flow fluorometer was used to detect changes in evanescent wave fluorescence. A fluorescein (FL) conjugate of

Optical fiber-based biosensors
Analytical and Bioanalytical Chemistry, 2004This review outlines optical fiber-based biosensor research from January 2001 through September 2003 and was written to complement the previous review in this journal by Marazuela and Moreno-Bondi. Optical fiber-based biosensors combine the use of a biological recognition element with an optical fiber or optical fiber bundle. They are classified by the

A Transparent Nanostructured Optical Biosensor
Journal of Biomedical Nanotechnology, 2014Herein we report a new transparent nanostructured Fabry-Perot interferometer (FPI) device. The unique features of the nanostructured optical device can be summarized as the following: (i) optically transparent nanostructured optical device; (ii) simple and inexpensive for fabrication; (iii) easy to be fabricated and scaled up as an arrayed format ...

Optical grating coupler biosensors
Biomaterials, 2002By incorporating a grating in a planar optical waveguide one creates a device with which the spectrum of guided lightmodes can he measured. When the surface of the waveguide is exposed to different solutions, the peaks in the spectrum shift due to molecular interactions with the surface.

Optical biosensors in drug discovery
Nature Reviews Drug Discovery, 2002Optical biosensors that exploit surface plasmon resonance, waveguides and resonant mirrors have been used widely over the past decade to analyse biomolecular interactions. These sensors allow the determination of the affinity and kinetics of a wide variety of molecular interactions in real time, without the need for a molecular tag or label.

Optical biosensors for detection of exosomes
Clinica Chimica ActaExosomes, nanoscale extracellular vesicles secreted by various cell types, have emerged as critical mediators of intercellular communication and valuable indicators of physiological and pathological states. Their stable presence in biofluids and ability to carry disease-specific molecular cargo make them ideal candidates for non-invasive diagnostics ...
