Rapid Biosensor-Based Detection of Environmental Contamination by Petroleum Hydrocarbons, PAHs and Heavy Metals
Nigel J Silman*, Jeremy G Thomas & Peter Riggs

In this study, we evaluated different freeze-drying excipients to stabilise the biosensor and remove the requirement to store bacteria at -20??C.

Prospecting For Iron and Titanium Using Termitaria
Kinachu James. G, Kiptoo Jackson. K, Onditi Anam.O.

This study demonstrated elevated levels of the two metals (that is iron and titanium) in termitaria soil compared to the surrounding soils. Termitaria are very important bioturbators and can therefore be used as preliminary step in mineral prospecting since they provide an indication of the potential of the positive anomaly, and enables a judgment on the scale of the metal accumulation

A Microfluidic Device for Detection of Water Contamination from Hydraulic Fracturing
Leslie J. Loh, Gayan C. Bandara, Christopher A. Heist and Vincent T. Remcho

A paper-based microfluidic device was designed and optimized for the colorimetric detection of bromide in water. This work was developed in response to the waste management challenges and pollution risks of hydraulic fracturing wastewater. This device is suitable for distribution as a field test as it is portable, easy to use, inexpensive and can be packaged to extend shelf life.

An Alternative to Direct Probe: Pyroprobe Coupled to High Resolution Time-of-Flight Mass Spectrometry
Jonathan D. Byer, Joe Binkley, Karen Sam, Jeff Patrick

Direct Pyroprobe is not a substitute for direct probe, but there is some overlap, as well as additional functionality. Direct probes coupled to LECO Pegasus instruments provide unique features:
– Time-of-flight mass spectra which shows little-to-no spectral skewing
– Automatic peak finding and spectral deconvolution for better identification
– Pegasus HT has a very low maintenance source which is beneficial for direct analysis techniques

Aptamer-Based Electrochemical Biosensing Platform for Detection of Hormonal Pollutants in Water
Contreras Jimenez, G.; Eissa, S.; Ng, A.; Zourob, M.; Siaj, M.

A novel detection mechanism based on aptamers has been developed to detect small molecules as hormones, antibiotics, toxins, drugs, etc. For first time, an aptasensor to detect progesterone has been developed.

Field Performance of a New Technology with the Potential to Identify Allergy and Asthma Triggers
Julian Gordon, PhD, Prasanthi Gandhi, MBA, MPH1, Jack A.Gilbert, Jarrad T. Hampton-Marcell

This work introduces a very simple plug-and-play device that can sample air at a high volume flow rate with no moving parts. Aerosol particles are captured on electrodes and eluted for testing. We show that performance of the device is substantially equivalent to capture by pumping through a filter for immunological and molecular analysis.
