Design of a Wireless Passive Microsensor for Injection into the Human Brain

Spratley J.P.F., Hall P.S., Ward M.C.L., University of Birmingham, UK

The design of a sensor for injection into the human brain to aid sufferers of spinal injuries and neurological dissorders is outlined. It is powered and communicates by induction from an external coil, and incorporates [...]

Remote Manipulation of a Robotic Arm by Using Infrared Sensors

Chávez Rodríguez N.E., Esquivel Villar J., UNAM, MX

This project consists in adapting a remote operation system for a robotic arm by using infrared sensors to control its movements. A personal com-puter was used to send instructions to the robotic arm, instead of [...]

Stem Cell Differentiation Base on Acoustic Wave Sensor

Shih C-J, Tsai B-C, Ou K-L, Industrial Technology Research Institute, TW

This project was based on immobilizing bio-material. We used a new application for protein array and studied a new acoustic wave sensor which is based on silicon. We used the MEMS fabrication and the property [...]

Ligand-dependent changes in the SPR of magnetic nanoparticles

Radu L., Caruntu D., White M., Wiley J., Hanson P., University of New Orleans, US

Currently, there is an increasing interest in using magnetite nanoparticles in biological and medical applications. The interest is driven by a combination of their biocompatibility, chemical stability and magnetic properties. Magnetite nanoparticles with diameter 10 [...]

Fast and Easy Detection System of Protein Glycosylation by Using Resonant Energy Transfer between Nanoparticles

Oh E., Lee D., Kim H-S, Korea Advanced Institute of Science and Technology, KR

We construct the new glycosylation detection system using Resonance Energy Transfer (RET) between gold nanoparticles (AuNPs) and semiconductor quantum dots (QDs). RET can be induced by biomolecular interactions between concanavalin A (conA)-conjugated AuNP (conA-AuNP) as [...]

Applications of Dielectrophoretic / electrohydrodynamic electrodes for concentration of biological nanoparticles

Fatoyino H.O., Huebner Y., Hoettges K.F., Hughes M.P., Labeed F.H., University of Surrey, UK

Dielectrophoresis (DEP) is a phemomenon of induced particle motion in non-uniform electric fields. The effect is frequency dependent; by monitoring the motion of particles in AC fields and ananlysing the change in motion with frequency, [...]

Nanoengineered Encapsulation of Organic Microcrystal as Novel Biolabels

Mak W.C., Cheung K.Y., Renneberg R., Trau D., National University of Singapore, SG

Here we report on our latest developments for nanoengineered encapsulation and surface design of micro and submicron crystals for biochemcial assay. Improvement has been made by decreasing the size of the organic crystals to submicrometer [...]

Biomolecular diagnostics by a magnetic lab-on-a-chip

Brückl H., Eggeling M., Heer R., Nöhammer C., Schotter J., ARC Seibersdorf Research GmbH, AT

Compared to the established fluorescent labeling method, the use of magnetic markers in biochip sensors has important advantages with respect to the detection of biomolecules at low concentrations. Additionally, the direct availability of an electronic [...]

A Sensitive Peptide-Nanotube Based Pathogen Assay

MacCuspie R.I., Banerjee I.A., Gummalla S., Mostowski H., Krause P., Matsui H., Hunter College, US

A novel peptide nanotube-based multiplexed pathogen assay has been developed that has high sensitivity, detecting as few as 100 pathogens per mL in as little as 0.5mL. Multifunctional nanotubes detect viruses by selectively binding antibody [...]

Direct-Write CMOS-Based Laboratory-On-Chip

Ghafar-Zadeh E., Sawan M., Therriault D., École Polytechnique de Montréal, CA

Over the recent years, the identification of genes which influence many diseases has been highly demanded and now, molecular diagnosis is most promising technology to offer fast and early detection of diseases to a maximum [...]
