Chitosan/poly(vinyl alcohol)/gelatin (CS/PVA/GA) ternary blend films were prepared by solution blending method in this study. The thermal properties of the CS/PVA/GA ternary blend films were examined by differential scanning calorimetry (DSC), and thermogravimetric analysis (TGA). The melting point of the CS/PVA/GA ternary blend film was increased when the(More)
A multiplexed immunosensor has been developed for the detection of specific biomarkers Galectin-1 (Gal-1) and Lactate Dehydrogenase B (LDH-B) present in different grades of bladder cancer cell lysates. In order to immobilize nanoprobes with different antibodies on a single chip we employed three-step programmable dielectrophoretic manipulations for(More)
A novel modification of low-cost Al₂O₃ nanoparticles (Al₂O₃ NPs) for antibody-protein immunosensing is proposed. The modified NPs are utilized to enhance the intensity of fluorescence in a dielectrophoretic (DEP) chip with a microelectrode array. The surface of the Al₂O₃ NPs is modified by ionic polyaniline (PANDB) rather than the conventional silane(More)
Quantitative analysis of user behavior calls for automated collection of large amount of log data over time. In this paper, we present a service platform for logging and analyzing mobile user behaviors. We have implemented a log collection service which records all user operations on the mobile unit. The collected data are transmitted to a remote server(More)
An ultrasensitive and real-time impedance based immunosensor has been fabricated for the quantitative detection of Galectin-1 (Gal-1) protein, a biomarker for the onset of multiple oncological conditions, especially bladder cancer. The chip consists of a gold annular interdigitated microelectrode array (3×3 format with a sensing area of 200µm) patterned(More)
The rheological properties and critical behavior of konjac glucomannan (KGM)/xanthan (XG) mixed gels were investigated and analyzed using a two-component cascade model. The fitting results show that the optimal functionality value for KGM (fKGM) is 3, whereas the possible functionality value for XG (fXG) is 100-1000 obtained from the modulus data, or 25(More)

The gelation of konjac glucomannan (KGM) often involves an induction period featured by an initial drop in modulus. The gelation kinetics recorded as a time-dependent modulus change is composed of an initial drop followed by a steady increase in modulus until an equilibrium stage is reached. In this work, the time-dependent modulus curve is described by a(More)
Point-of-care testing (POCT), or bedside testing is defined as medical testing at or near the site of patient care. In order to approach POCT, a miniaturization system consists of microfluidics chip, bio-recognition probes and electrically sensing element for providing enough information on clinical diagnosis. As the result, multidisciplinary researches and(More)
