pH-Sensitive Hydrogel for Micro-Fluidic Valve
The deformation behavior of a pH-sensitive hydrogel micro-fluidic valve system is investigated using inhomogeneous gel deformation theory, in which the fluid-structure interaction (FSI) of the gel solid and fluid flow in the pipe is considered. We use a finite element method with a well adopted hydrogel constitutive equation, which is coded in commercial software, ABAQUS, to simulate the hydrog...
متن کاملOptical pH Sensor Based on Quinizarin for Alkaline pH Regions
The development of an optical pH sensor based on immobilization of quinizarin (1,4-dihydroxyanthraquinone) on a triacetylcellulose membrane was described. The resulting membrane exhibited fast color change from yellow to violet, while changing the pH in alkaline region. The immobilized quinizarin showed a broader dynamic range from (pH 9.4-11.4) with respect to free form (pH 8.8-10.4). The sens...
متن کاملMeasurement of pH and dissolved oxygen within cell culture media using a hydrogel microarray sensor
The sensing of analytes in cell culture media without the introduction of exogenous reagents proves difficult in today’s cell culturing systems. In his paper, a completely embeddable microarray sensor that has been developed along with a compact fluorescent imaging system to sense oxygen nd pH non-invasively is described. The compact detection system consists of an ultra-bright blue diode sourc...
متن کاملpH-Controllable drug release using hydrogel encapsulated mesoporous silica.
Amine-functionalized mesoporous SBA-15 silica loaded with bovine serum albumin (BSA) has been successfully encapsulated with a thin layer coating of poly(acrylic acid) PAA, with the entrapped BSA being released from the PAA-encapsulated SBA-15 at the higher pH value of 7.4 rather than at the lower pH value of 1.2. This novel drug delivery system has a potential application in the release of pro...
متن کاملComparison of pH Data Measured with a pH Sensor Array Using Different Data Fusion Methods
This paper introduces different data fusion methods which are used for an electrochemical measurement using a sensor array. In this study, we used ruthenium dioxide sensing membrane pH electrodes to form a sensor array. The sensor array was used for detecting the pH values of grape wine, generic cola drink and bottled base water. The measured pH data were used for data fusion methods to increas...
