Noninvasive photonic-crystal material for sensing glucose in tears.
Most noninvasive (NI) methods for the determination of glucose either detect a small specific glucose signal or measure the effect of glucose on a tissue optical property (1, 2). A recent review identified the three main issues in NI glucose measurements as specificity, compartmentalization of glucose values, and calibration (1 ). This editorial discusses a photonic crystal method (3 ), with re...
متن کاملPhotonic crystal glucose-sensing material for noninvasive monitoring of glucose in tear fluid.
BACKGROUND We recently developed a photonic crystal glucose-sensing material, which consists of a crystalline colloidal array embedded within a polymer network of a polyacrylamide-poly(ethylene glycol) hydrogel with pendent phenylboronic acid groups. The aim of the present work was to improve this approach for application to noninvasive or minimally invasive monitoring of glucose. METHODS We ...
متن کاملConstruction of near-infrared photonic crystal glucose-sensing materials for ratiometric sensing of glucose in tears.
Noninvasive monitoring of glucose in tears is highly desirable in tight glucose control. The polymerized crystalline colloidal array (PCCA) that can be incorporated into contact lens represents one of the most promising materials for noninvasive monitoring of glucose in tears. However, low sensitivity and slow time response of the PCCA reported in previous arts has limited its clinical utility....
متن کاملHigh ionic strength glucose-sensing photonic crystal.
We demonstrate a colorimetric glucose recognition material consisting of a crystalline colloidal array embedded within a polyacrylamide-poly(ethylene glycol) (PEG) hydrogel, or a polyacrylamide-15-crown-5 hydrogel, with pendent phenylboronic acid groups. We utilize a new molecular recognition motif, in which boronic acid and PEG (or crown ether) functional groups are prepositioned in a photonic...
متن کاملHybrid photonic crystal fiber in chemical sensing
BACKGROUND In this article, a hybrid photonic crystal fiber has been proposed for chemical sensing. A FEM has been applied for numerical investigation of some propagation characteristics of the PCF at a wider wavelength from 0.7 to 1.7 µm. The geometrical parameters altered to determine the optimized values. The proposed PCF contains three rings of circular holes in the cladding where the core ...
