A Noninvasive Fluorescent Biosensor for Transdermal Glucose
Our group has been developing a painless, noninvasive method of collecting glucose spontaneously/passively diffusing through the skin. The transdermal glucose collected in this manner has a concentration in the μM range, thus we developed a [...]
Linear-Logarithmic Two-Transistor Active Pixel Sensor with Wide Dynamic Range
Image sensor technology has progressed from advanced semiconductor technology. The complementary metal–oxide–semiconductor (CMOS) process offers the capability of integrating smart functions on imagers in a single chip. As CMOS technology scales down, the pixel size [...]
Optical Fiber-Top Microcavity Sensor for CO2 Detection
Wu J., Yin M-J, Taeuber K., Dani A., Guterman R., Yuan J., Zhang A.P., Tam H-Y, The Hong Kong Polytechnic University, HK
In the paper, we present a miniature fiber-optic CO2 sensor by in-situ printing of a special polymer Fabry-Pérot (FP) microcavity on the end facet of standard single-mode optical fiber. A photo-crosslinkable poly(ionic liquid)s (PILs) with [...]
Fiber-optic sensor for bacteria detection based on intensity-modulated SPR by monochromatic excitation
da Silva Arcas A., da Silva Dutra F., da Silva Arcas A., da Silva Dutra F., Barros Allil R.C.S., Werneck M.M., Federal University of Rio de Janeiro, BR
The Escherichia coli (E. coli) O157:H7 is a human pathogen of animal origin that can cause serious illness if ingested. The most common routes of E. coli contamination are drinking water, vegetables, undercooked meat, unpasteurized [...]
Comparative study of chemo-bio synthesized MgO nano particles for LPG sensing
Present work is a comparative study for LPG sensor which is developed by two materials by chemical and green method. LPG sensing dynamic characteristics were examined.
Visible Light Absorbing Photoremovable Protecting Groups
Photoremovable protecting groups (or “photocages” or “phototriggers”) are light-sensitive chemical moieties that provide control over the release of any number of reagents in a variety of environments. While photocages have important applications in areas such [...]
Evaluation of In2O3 prepared by the delayed ignition combustion process as a gas sensor
Lionti K., Fasoli A., Sundberg L., Ceccarelli F., Miller R.D., Bozano L., IBM Research - Almaden, US
Metal oxide semiconductor (MOS) gas sensors based on thin film technology offer the potential of higher sensitivity and faster response and recovery than their thick film counterparts. Solution-based approaches are facile and inexpensive routes to [...]
Cyber-Physical Magnetic Field Sensors
Solid state magnetic field sensors are examined. The use of III-V semiconductors in Hall effect sensors results in high bandwidth, fast response time, adequate spatiotemporal resolution, accuracy and sufficient measurement range. Despite significant advantages, there [...]
Zinc Oxide optical and chemical sensors fabricated by Ink Jet printing and drop casting
Ewing D.J., Casper M., Stramel A., Morick B., Cook B., Wu J., The Department of Energy's Kansas City National Security Campus, US
Zinc oxide (ZnO) nanostructures show great promise for a variety of applications, such as UV detectors, chemical, and gas sensors. Zinc oxide has a direct bandgap (3.4 eV), a high electron mobility, and environmental stability. [...]
