The latest issue of Analyst is now online, and we’re all about urgency as two exciting Communications feature on the covers.
On the front cover is work from Marcos Eberlin of the University of Campinas, São Paulo, Brazil and his colleagues. They describe a simplified, fully portable version of Venturi easy ambient sonic-spray ionization (V-EASI) that now eliminates the need of laboratory gas cylinders and regulators. This source, they say, seems to be one of the easiest to assemble and use, most economical yet effective and versatile platforms for ambient desorption/ionization mass spectrometry analysis of both solid and liquid samples. Did you know that Marcos is an Associate Editor for our sister journal RSC Advances? Find out more here.
Communication: Easy dual-mode ambient mass spectrometry with Venturi self-pumping, canned air, disposable parts and voltage-free sonic-spray ionization

Some of you may think that our inside front cover looks familiar, and you’d be right…
The inside front cover highlights work that we have previously featured as a HOT article, and which was featured in Chemistry World. Aydogan Ozcan and his group at the University of California, Los Angeles, USA have developed a device that, when attached to a mobile phone, can detect small amounts of Escherichia coli in liquid samples. The team tested the device using water samples and milk and were able to selectively detect low concentrations of E. coli, even in the presence of other bacterial species.
Communication: Quantum dot enabled detection of Escherichia coli using a cell-phone
Hongying Zhu, Uzair Sikora and Aydogan Ozcan
