Journal Highlight: Manipulating particles in microfluidics by floating electrodes
An international team of scientists has used single or double floating electrodes to finely control the movement of charged particles, including concentrating them into specific sections of a microchannel.
Biting down on germ detection: Combining electrophoresis and dielectrophoresis
Using insulating structures shaped like sharp teeth, US scientists have managed to combine electrophoresis and dielectrophoresis on a single microfluidic device, which can separate particles that differ widely in size.
Journal Highlight: Summer distribution and diversity of aerobic anoxygenic phototrophic bacteria in the Mediterranean Sea in relation to environmental variables
French and US scientists have used temporal temperature gel gradient electrophoresis to investigate the distribution and genetic diversity of aerobic anoxygenic phototrophic bacteria collected from the Mediterranean Sea.
Solvent Microextraction: Theory and Practice
This book offers both a practical as well a theoretical approach to Solvent Microextraction (SME) and will help analytical chemists to evaluate SME for a given sample preparation. Introductory chapters overview a comparison of SME with other sample preparation methods, a summary of the technical aspects, and a detailed theoretical treatment of SME. The book then describes the practical aspects of the technique, with detailed "how to" chapters devoted to the preparation and analysis of atmospheric, solid and liquid environmental, clinical and industrial samples. This text will serve as both a handy laboratory desk-reference and an indispensible instructional tool.
