HOT Article: Detecting people in collapsed buildings
22 Jun 2012
Mochalski & Amman et al., Analyst, 2012, 137, 3278
In the last few years there have been a number of large natural disasters, including the earthquakes in Haiti and Indonesia, and the earthquake and subsequent tsunami in Japan. These disasters result in devastation and the collapse of buildings and infrastructure in cities, town and villages. Search and rescue teams looking for survivors in the rubble currently use techniques like geophones, telescopic cameras, infrared (IR) cameras, or search dogs to locate survivors. Paweł Mochalski, Anton Amann and a collaborative team from Poland, Austria and Greece have used headspace solid phase micro-extraction gas chromatography-mass spectrometry to study the biomarkers in urine, and looked at how the profile of 22 volatile species in urine changed when in contact with concrete and brick, in an attempt to signify human presence. Read about their interesting study below.

On the front cover we have an image from Tai Hyun Park, Seunghun Hong and colleagues from Seoul National University, Seoul, Korea. They have developed a biosensor that works on the same principles as the canine nose and have used it in the detection of hexanal, which is an indicator of the oxidation of food and food quality.

Tarkeshwar Gupta from the University of Delhi and co-workers from India and Germany have given us our inside front cover this issue. In their communication they have made an efficient sensor for ascorbic acid using a copper complex-based monolayer on glass. They hope this is a step forward in research in monolayer-based remote-sensing devices and wireless sensor fabrication.

HOT article: Monitoring chicken meat freshness by colorimetric sensor
13 Jun 2012
Scientists in Spain used an array of 16 chromogenic indicators with different chemical recognition properties to follow the ageing of chicken stored in modified atmosphere packaging (MAP).
Many currently available methods to check meat spoilage are destructive, time-consuming, expensive and require qualified personnel. This means that they are fine for food safety inspections, but not suitable for use in shops or on every piece of packaged meat. Chromogenic sensors are cheap, versatile, can be printed on packaging and easily measured by cameras or the naked eye. The team observed characteristic colour fingerprints for each day of the study (which was carried out over 12 days) and gave clear differentiation at two-day intervals.
Once the 16-dye array had been successfully used, the team developed a simpler version based on just two dyes with three categories allowing differentiation between ‘fresh’, ‘beginning of decay’ and ‘non-fresh’. This shortened version could be printed on packaging and observed by the naked eye.

HOT article: Saliva sample collector for non-invasive health test
13 Jun 2012
Monitoring volatile organic compound (VOC) levels in workers exposed to these compounds is important for their health. This is normally done by taking blood samples. However, scientists are looking towards using saliva samples instead, as a non-invasive technique.
Collecting saliva samples is done by either passive drool (in which the subject has to sit tight while their saliva drips off their lips into a collection vessel) or by chewing on a piece of cotton wool (which is then centrifuged to collect the saliva). But, neither technique can be used to detect VOCs in saliva.
Now, UK scientists at Loughborough University and Unilever R&D in the Wirral have come up with a new approach to overcome this problem. They carried out sampling of VOCs directly in the mouth using a polydimethylsiloxane sampler.
Although it takes 10 minutes to collect a sample, the team says that they are working towards reducing the time to one minute. The method could be combined with other VOC sampling methods – breath and skin analysis – they say.
