Alcohol conent measuring system based in interstitial fluid extraction and SAW sensors

Gnadinger A., Gnadinger P., Gnadinger A., Gnadinger P., COGNA Scientific LLC, US

There is a need for a an easy to use, reliable, accurate and inexpensive blood alcohol content measurement system. Currently, alcohol content is measured by taking and analyzing a blood sample. This method is not [...]

Label-free, rapid Listeria monocytogenes biosensor based on a stimulus response nanobrush and nanometal hybrid electrode

Althawab S., Oliveira D.A., Smith C., McLamore E.S., Gomes C., Texas A&M University, US

Recent foodborne outbreaks have heightened public concern about food safety and created a greater impetus to improve methods for foodborne pathogen detection. The most prevalent foodborne pathogens that persistently cause infections include Salmonella Typhimurium, Listeria [...]

Sensing Solution for Airborne Carbon Nanotube Exposure in Workplaces Based on Surface-Enhanced Raman Spectroscopy

Bieri R., Borek-Donten J., Celikkol Zijlstra B., Cattaneo S., Bürgi T., Stat Peel, CH

Today’s advances in man-made nanomaterials pose new and unprecedented health risks, arising especially from airborne, inhalable fiber-shaped nanomaterials, like carbon nanotubes (CNTs). In vivo studies indicate that inhalation of CNTs can cause adverse pulmonary effects [...]

Organic Nanobiomimetic Memristor/Memcapacitor Devices Ultrasensitive Direct Detect Matrix Matelloproteinase-2 in Human Serum

Chen E.T., Thornton J., Duh S-H, Advanced Biomimetic Sensors, US

Matrix Matelloproteinase-2 (MMP-2) plays a key role in many diseases. A new type of dual-functioning device was developed for fast, direct ultrasensitive detection of MMP-2 using NIST SRM965A reference human serum specimens under label-free, probe-free [...]

Discharge Region Sensing Technology of High Voltage Equipment Based on The Testing of The Corona Radiation Field

Chuang W., Xi C., Geng-chen S., Kai T., Beijing Institute of Technology, CN

High voltage discharge sensing using corona discharge electromagnetic radiation field is an important means to evaluate the reliability and safety of high voltage equipment during operation. But the traditional corona discharge electromagnetic radiation field testing [...]

Williams M., Lewis M., Gibson T., Lane J., Ihlefeld C., National Aeronautics and Space Adminstration, US

Martha K, Williams, Ph.D., Mark E. Lewis, Tracy L. Gibson, Ph.D., John E. Lane, Ph.D. and Curtis M. Ihlefeld The damage detection sensory system is an intelligent damage detection “skin” that can be embedded into [...]

Rapid Detection of Drugs-of-abuse in Urine and Oral Fluid by Mass Spectrometry

Ng T-T, Hu B., So P-K, Yao Z., The Hong Kong Polytechnic University, HK

Drug analysis is crucial for control of drugs abuse. Conventional drug analysis typically involves preliminary screening, followed by confirmatory analysis. However, the preliminary screening has the problem of producing false positive or false negative results, [...]

Distributed Monitoring of Soil and Groundwater during In-Situ Thermal Remediation Using Fiber Optic Sensors

Alemohammad H., Azhari A., Liang R., AOMS Technologies Inc., CA

This paper is focused on the development and field deployment of a multi-parameter and distributed fiber optic sensor for monitoring of soil and groundwater during in-situ thermal remediation of contaminated brownfields. In-situ thermal remediation (ISTR) [...]

A model for an Optical Ring Microresonator towards Nanoparticle Detection

Ahmeti F., Teker K., Istanbul Sehir University, TR

Optical resonators have shown great potential as fundamental building blocks, in a wide range of photonic devices and applications including filters, optical multiplexers, logic gates, switches and sensors. A microresonator is defined by a micron-scale [...]
