In this issue of Analyst we have two lovely covers for you to admire. On the outside we have an image from Sangmin Jeon and colleagues from Pohang University of Science and Technology, Korea. In their paper they report a new way of detecting Salmonella bacteria, a common cause of food poisoning. This simple, rapid, and cost-effective method used magnetic (superparamagnetic) nanoparticles and TiO2 nanocrystals.

From Zhong-Ping Yao at The Hong Kong Polytechnic University, China, comes the inside front cover. Together with a team from around China, they have been analyzing biological tissue at the molecular level. They have been able to directly ionize and analyze both plant and animal tissue by mass spectrometry under ambient conditions.
