New Type of High Sensitive Detection of Particles Based on DeFET

Ibrahim M.F., Elsayed F., Ghallab Y.H., Badawy W., University of Calgary, CA

This research work presents a new implementation of the CMOS electric-field sensor, titled as Differential Electric Field Sensitive Field Effect Transistor (DeFET). The DeFET is successfully used in detection of small partials and it is [...]

Fabry-Perot Diaphragm Fiber Optic Sensor (DFOS) for Acoustic Detection

Sun Y., Feng G., Georgiou G., Padron I., Niver E., Noe K., Chin K.K., New Jersey Institute of Technology, US

The diaphragm fiber optic sensor (DFOS) solely based on Fabry-Perot has been designed and fabricated with Micro-electric mechanical system(MEMS) technology. The DFOS utilizes a diaphragm as the sensing element to detect static and dynamic pressure [...]

Manufacturable, Highly Responsive Nanowire Mercury Sensors

Keebaugh S., Nam W.J., Fonash S.J., The Pennsylvania State University, US

We have developed a manufacturable and highly responsive gold nanowire sensor capable of detecting ppb concentrations of mercury in air and water. The nanowire sensor exhibits a superior response compared to thin film sensors and [...]

Devices for Nanoparticle-based Cancer Detection

Kim G.Y., Daniel K.D., Vassiliou C.C., Elman N., Josephson L., Cima M.J., MIT, US

This implantable biomarker sensor combines nanoscale magnetic relaxation switches (MRSW) and the versatility of microfabricated structures tp be read by MRI. MRSW are magnetic iron oxide nanoparticles that can be functionalized to detect a variety [...]

Interaction of DNA with Single-Walled Carbon Nanotubes: Implication to the Bio-Sensors

Kong K-J, Chang H., Lee J-O, Korea Research Institute of Chemical Technology, KR

Here, we have briefly introduced the recent progresses in experiments of DNA sensing with CNT-FET sensors and theoretical investigations to explore the sensing mechanism.

Sensor application of ZnO nanowires on microheater

Park J., Kim G.-T., Maeng S., Udrea F., Milne W., ETRI, KR

We fabricated the ZnO nanowire network device using sol-gel synthesis method on the pre-patterned electrode and tested the electrical property for chemical sensing. The electrodes were prepared in various ways, for example, photolithographically defined interdigitated [...]
