Potyrailo et al., Analyst, 2012, 137, 2777-2781
Take a look at the latest issue of Analyst.
Featured on the front cover is work from Radislav Potyrailo of GE Global Research, Niskayuna, New York, USA, and co-workers. They demonstrate roll-to-roll (R2R) fabrication of highly selective, battery-free radio frequency identification (RFID) sensors on a flexible polyethylene terephthalate (PET) polymeric substrate. Their RFID sensing concept features 16-bit resolution provided by the sensor reader, granting a highly desired independence from costly proprietary RFID memory chips with a low-resolution analog input. Future steps are being planned for field-testing of these sensors in numerous conditions.
Multivariable passive RFID vapor sensors: roll-to-roll fabrication on a flexible substrate

On the inside front cover, Hans-Peter Loock and colleagues from Queen’s University, Kingston, Canada, look at online monitoring of the contamination of fuel with lubricants. They demonstrate that fiber-based Cavity-Ring-Down (CRD) absorption spectroscopy, and fluorescence Excitation–Emission Matrix (EEM) spectroscopy can provide the information that is needed to detect and quantify contamination and degradation products in machinery fluids.
