Surface Plasmon Resonance (SPR) biosensors have emerged as a promising technique for bioanalysis as well as microbial detection and identification. Real time, sensitive, cost effective, and label free detection of biomolecules from complex samples is required for early and accurate diagnosis of infectious diseases. Like many other types of optical techniques, SPR biosensors may also be successfully...
A novel approach to the surface functionalization for membraneless enzymatic glucose/oxygen biofuel cell applications is described. The biofuel cell employs the gold plate electrodes modified by specific graphene-enzyme conjugations, which are immobilized by electrochemical deposition of the conducting polypyrrole polymer. The electrochemical activity of these electrodes is superior to the electrodes...
Molecular cancer biomarkers will be instrumental in the screening and detection of cancer. Development of a hand held, non destructive microsensor for distinguishing breast cancer cells in real time is essential for breast cancer therapeutic options. Vascular Endothelial Growth Factor (VEGF) is a potent cytokine, which is normally over-expressed in malignant breast tumor cells. In our work, we are...
Electrorotation has become a very powerful diagnostic technique for measurement of dielectric properties of cells. However, only few papers investigated in the electric-induced rotation of particles in a stationary alternating (AC) electric field instead of a rotating electric field. In this study, a microchip comprised top grounded electrode, flow chamber and bottom chess-type electrode arrays to...
