This month we have a HOT article from the Chair of our Editorial Board, Paul Bohn. Together with his colleague Sean Branagan from the University of Notre Dame, US, they have been looking at thin Au films, patterned by focused ion beam (FIB) milling to contain an array of subwavelength nanopores, and how they exhibit enhanced optical transmission (EOT) via front–back resonance coupling.

Agnieszka Banas and Mark Breese from the National University of Singapore, and colleagues from Singapore and the UK have discovered there is more to be revealed in fingerprints. The non-destructive technique of synchrotron radiation-based Fourier transform infra-red (SR-FTIR) micro-imaging has been used to explore the molecular chemistry within the microstructures of microscopic particles found within latent fingerprints. Fingerprints can be contaminated with all sorts of things that a person has come in contact with, like powders, creams, medications and high explosive materials.

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.

Permeation profiles of potential urine-borne biomarkers of human presence over brick and concrete
