Photonic crystal carbohydrate sensors: low ionic strength sugar sensing.
We developed a carbohydrate sensing material, which consists of a crystalline colloidal array (CCA) incorporated into a polyacrylamide hydrogel (PCCA) with pendent boronic acid groups. The embedded CCA diffracts visible light, and the PCCA diffraction wavelength reports on the hydrogel volume. This boronic acid PCCA responds to species containing vicinal cis diols such as carbohydrates. This PC...
متن کاملLabel-free silicon photonic biosensor system with integrated detector array.
An integrated, inexpensive, label-free photonic waveguide biosensor system with multi-analyte capability has been implemented on a silicon photonics integrated circuit from a commercial CMOS line and tested with nanofilms. The local evanescent array coupled (LEAC) biosensor is based on a new physical phenomenon that is fundamentally different from the mechanisms of other evanescent field sensor...
متن کاملMeasurement of bound states in the continuum by a detector embedded in a photonic crystal
We directly measure optical bound states in the continuum (BICs) by embedding a photodetector into a photonic crystal slab. The BICs observed in our experiment are the result of accidental phase matching between incident, reflected and in-plane waves at seemingly random wave vectors in the photonic band structure. Our measurements were confirmed through a rigorously coupled-wave analysis simula...
متن کاملW-band photonic-wireless link with a Schottky diode envelope detector and bend insensitive fiber.
The performance and potential of a W-band radio-over-fiber link is analyzed, including a characterization of the wireless channel. The presented setup focuses on minimizing complexity in the radio frequency domain, using a passive radio frequency transmitter and a Schottky diode based envelope detector. Performance is experimentally validated with carriers at 75-87GHz over wireless distances of...
متن کاملSugar and sugar products.
Emphasis over the past year has been on editorial effort to bring Chapter 44, Sugar and Sugar Products of the Official Methods of Analysis of AOAC INTERNATIONAL (OMA) to the high standards set for the 17th Edition of the compendium. In addition, 2 method studies were reported and subjected to peer review, respectively, dealing with detection of adulteration of maple syrup by beet or cane sugar ...
